DESCRIPTION
mplayer is a movie player for Linux (runs on many other platforms and
CPU architectures, see the documentation). It plays most MPEG/VOB,
AVI, ASF/WMA/WMV, RM, QT/MOV/MP4, Ogg/OGM, MKV, VIVO, FLI, NuppelVideo,
yuv4mpeg, FILM and RoQ files, supported by many native and binary
codecs. You can watch VCD, SVCD, DVD, Blu-ray, 3ivx, DivX 3/4/5, WMV
and even H.264 movies, too.
MPlayer supports a wide range of video and audio output drivers. It
works with X11, Xv, DGA, OpenGL, SVGAlib, fbdev, AAlib, libcaca,
DirectFB, Quartz, Mac OS X CoreVideo, but you can also use GGI, SDL
(and all their drivers), VESA (on every VESA-compatible card, even
without X11), some low-level card-specific drivers (for Matrox, 3dfx
and ATI) and some hardware MPEG decoder boards, such as the Siemens
DVB, Hauppauge PVR (IVTV) and DXR3/Hollywood+. Most of them support
software or hardware scaling, so you can enjoy movies in fullscreen
mode.
MPlayer has an onscreen display (OSD) for status information, nice big
antialiased shaded subtitles and visual feedback for keyboard controls.
European/ISO8859-1,2 (Hungarian, English, Czech, etc), Cyrillic and
Korean fonts are supported along with 12 subtitle formats (MicroDVD,
SubRip, OGM, SubViewer, Sami, VPlayer, RT, SSA, AQTitle, JACOsub, PJS
and our own: MPsub) and DVD subtitles (SPU streams, VOBsub and Closed
Captions).
Usage examples to get you started quickly can be found at the end of
this man page.
Also see the HTML documentation!
INTERACTIVE CONTROL
MPlayer has a fully configurable, command-driven control layer which
allows you to control MPlayer using keyboard, mouse, joystick or remote
control (with LIRC). See the -input option for ways to customize it.

USAGE
Every 'flag' option has a 'noflag' counterpart, e.g. the opposite of
the -fs option is -nofs.
If an option is marked as (XXX only), it will only work in combination
with the XXX option or if XXX is compiled in.
NOTE: The suboption parser (used for example for -ao pcm suboptions)
supports a special kind of string-escaping intended for use with
external GUIs.
It has the following format:
%n%string_of_length_n
EXAMPLES:
mplayer -ao pcm:file=%10%C:test.wav test.avi
Or in a script:
mplayer -ao pcm:file=%`expr length "$NAME"`%"$NAME" test.avi
CONFIGURATION FILES
You can put all of the options in configuration files which will be
read every time MPlayer is run. The system-wide configuration file
'mplayer.conf' is in your configuration directory (e.g. /etc/mplayer or
/usr/local/etc/mplayer), the user specific one is '~/.mplayer/config'.
User specific options override system-wide options and options given on
the command line override either. The syntax of the configuration
files is 'option=<value>', everything after a '#' is considered a
comment. Options that work without values can be enabled by setting
them to 'yes' or '1' or 'true' and disabled by setting them to 'no' or
'0' or 'false'. Even suboptions can be specified in this way.
You can also write file-specific configuration files. If you wish to
have a configuration file for a file called 'movie.avi', create a file
named 'movie.avi.conf' with the file-specific options in it and put it
in ~/.mplayer/. You can also put the configuration file in the same
directory as the file to be played, as long as you give the
-use-filedir-conf option (either on the command line or in your global
config file). If a file-specific configuration file is found in the
same directory, no file-specific configuration is loaded from
~/.mplayer. In addition, the -use-filedir-conf option enables
directory-specific configuration files. For this, MPlayer first tries
to load a mplayer.conf from the same directory as the file played and
then tries to load any file-specific configuration.
EXAMPLE MPLAYER CONFIGURATION FILE:
# Use Matrox driver by default.
vo=xmga
# I love practicing handstands while watching videos.
flip=yes
# Decode multiple files from PNG,
# start with mf://filemask
mf=type=png:fps=25
# Eerie negative images are cool.
vf=eq2=1.0:-0.8
PROFILES
To ease working with different configurations profiles can be defined
in the configuration files. A profile starts with its name between
square brackets, e.g. '[my-profile]'. All following options will be
part of the profile. A description (shown by -profile help) can be
defined with the profile-desc option. To end the profile, start
another one or use the profile name 'default' to continue with normal
options.
EXAMPLE MPLAYER PROFILE:
[protocol.dvd]
profile-desc="profile for dvd:// streams"
vf=pp=hb/vb/dr/al/fd
alang=en
[protocol.dvdnav]
profile-desc="profile for dvdnav:// streams"
profile=protocol.dvd
mouse-movements=yes
nocache=yes
[extension.flv]
profile-desc="profile for .flv files"
flip=yes
[vo.pnm]
outdir=/tmp
[ao.alsa]
device=spdif
GENERAL OPTIONS
-codecpath <dir>
Specify a directory for binary codecs.
-codecs-file <filename> (also see -afm, -ac, -vfm, -vc)
Override the standard search path and use the specified file
instead of the builtin codecs.conf.
-include <configuration file>
Specify configuration file to be parsed after the default ones.
-list-options
Prints all available options.
-msgcharset <charset>
Convert console messages to the specified character set
(default: autodetect). Text will be in the encoding specified
with the --charset configure option. Set this to "noconv" to
disable conversion (for e.g. iconv problems).
NOTE: The option takes effect after command line parsing has
finished. The MPLAYER_CHARSET environment variable can help you
get rid of the first lines of garbled output.
-msgcolor
Enable colorful console output on terminals that support ANSI
color.
-msglevel <all=<level>:<module>=<level>:...>
Control verbosity directly for each module. The 'all' module
changes the verbosity of all the modules not explicitly
specified on the command line. See '-msglevel help' for a list
of all modules.
NOTE: Some messages are printed before the command line is
parsed and are therefore not affected by -msglevel. To control
these messages you have to use the MPLAYER_VERBOSE environment
variable, see its description below for details.
Available levels:
-1 complete silence
0 fatal messages only
1 error messages
2 warning messages
3 short hints
4 informational messages
5 status messages (default)
6 verbose messages
7 debug level 2
8 debug level 3
9 debug level 4
-msgmodule
Prepend module name in front of each console message.
-noconfig <options>
Do not parse selected configuration files.
NOTE: If -include or -use-filedir-conf options are specified at
the command line, they will be honoured.
Available options are:
all
all configuration files
system
system configuration file
user
user configuration file
-quiet
Make console output less verbose; in particular, prevents the
status line (i.e. A: 0.7 V: 0.6 A-V: 0.068 ...) from being
displayed. Particularly useful on slow terminals or broken ones
which do not properly handle carriage return (i.e. \r).
-priority <prio> (Windows and OS/2 only)
Set process priority for MPlayer according to the predefined
priorities available under Windows and OS/2. Possible values of
<prio>:
idle|belownormal|normal|abovenormal|high|realtime
WARNING: Using realtime priority can cause system lockup.
-profile <profile1,profile2,...>
Use the given profile(s), -profile help displays a list of the
defined profiles.
-really-quiet (also see -quiet)
Display even less output and status messages than with -quiet.
-show-profile <profile>
Show the description and content of a profile.
-use-filedir-conf
Look for a file-specific configuration file in the same
directory as the file that is being played.
WARNING: May be dangerous if playing from untrusted media.
-v
Increment verbosity level, one level for each -v found on the
command line.
PLAYER OPTIONS
-autoq <quality> (use with -vf [s]pp)
Dynamically changes the level of postprocessing depending on the
available spare CPU time. The number you specify will be the
maximum level used. Usually you can use some big number. You
have to use -vf [s]pp without parameters in order for this to
work.
-autosync <factor>
Gradually adjusts the A/V sync based on audio delay
measurements. Specifying -autosync 0, the default, will cause
frame timing to be based entirely on audio delay measurements.
Specifying -autosync 1 will do the same, but will subtly change
the A/V correction algorithm. An uneven video framerate in a
movie which plays fine with -nosound can often be helped by
setting this to an integer value greater than 1. The higher the
value, the closer the timing will be to -nosound. Try -autosync
30 to smooth out problems with sound drivers which do not
implement a perfect audio delay measurement. With this value,
if large A/V sync offsets occur, they will only take about 1 or
2 seconds to settle out. This delay in reaction time to sudden
A/V offsets should be the only side-effect of turning this
option on, for all sound drivers.
-benchmark
Prints some statistics on CPU usage and dropped frames at the
end of playback. Use in combination with -nosound and -vo null
for benchmarking only the video codec.
NOTE: With this option MPlayer will also ignore frame duration
when playing only video (you can think of that as infinite fps).
-chapter-merge-threshold <number>
Threshold for merging almost consecutive ordered chapter parts
in milliseconds (default: 100). Some Matroska files with
ordered chapters have inaccurate chapter end timestamps, causing
a small gap between the end of one chapter and the start of the
next one when they should match. If the end of one playback
part is less than the given threshold away from the start of the
next one then keep playing video normally over the chapter
change instead of doing a seek.
-colorkey <number>
Changes the colorkey to an RGB value of your choice. 0x000000
is black and 0xffffff is white. Only supported by the fbdev,
svga, vesa, xmga, xover, xv (see -vo xv:ck) and directx video
output drivers.
-nocolorkey
Disables colorkeying. Only supported by the fbdev, svga, vesa,
xmga, xover, xv (see -vo xv:ck) and directx video output
drivers.
-correct-pts, -nocorrect-pts
Switches MPlayer to a mode where timestamps for video frames are
calculated differently and video filters which add new frames or
modify timestamps of existing ones are supported. Now enabled
automatically for most common file formats. The more accurate
timestamps can be visible for example when playing subtitles
timed to scene changes with the -ass option. Without
-correct-pts the subtitle timing will typically be off by some
frames. This option does not work correctly with some demuxers
and codecs.
-crash-debug (DEBUG CODE)
Automatically attaches gdb upon crash or SIGTRAP. Support must
be compiled in by configuring with --enable-crash-debug.
-doubleclick-time
Time in milliseconds to recognize two consecutive button presses
as a double-click (default: 300). Set to 0 to let your
windowing system decide what a double-click is (-vo directx
only).
-edlout <filename>
Creates a new file and writes edit decision list (EDL) records
to it. During playback, the user hits 'i' to mark the start or
end of a skip block. This provides a starting point from which
the user can fine-tune EDL entries later. See
http://www.mplayerhq.hu/DOCS/HTML/en/edl.html for details.
-fixed-vo, -nofixed-vo
-fixed-vo enforces a fixed video system for multiple files (one
(un)initialization for all files). Therefore only one window
will be opened for all files. Now enabled by default, use
-nofixed-vo to disable and create a new window whenever the
video stream changes. Some of the older drivers may not be
fixed-vo compliant.
-framedrop (also see -hardframedrop, experimental without
-nocorrect-pts)
Skip displaying some frames to maintain A/V sync on slow
systems. Video filters are not applied to such frames. For B-
frames even decoding is skipped completely.
-h, -help, --help
Show short summary of options.
-hardframedrop (experimental without -nocorrect-pts)
More intense frame dropping (breaks decoding). Leads to image
distortion! Note that especially the libmpeg2 decoder may crash
with this, so consider using "-vc ffmpeg12,".
-heartbeat-cmd
Command that is executed every 30 seconds during playback via
system() - i.e. using the shell.
NOTE: MPlayer uses this command without any checking, it is your
responsibility to ensure it does not cause security problems
(e.g. make sure to use full paths if "." is in your path like on
Windows). It also only works when playing video (i.e. not with
-novideo but works with -vo null).
This can be "misused" to disable screensavers that do not
support the proper X API (also see -stop-xscreensaver). If you
think this is too complicated, ask the author of the screensaver
program to support the proper X APIs.
EXAMPLE for xscreensaver: mplayer -heartbeat-cmd
"xscreensaver-command -deactivate" file
EXAMPLE for GNOME screensaver: mplayer -heartbeat-cmd
"gnome-screensaver-command -p" file
-hr-seek off|absolute|always
Select when to use precise seeks that are not limited to
keyframes. Such seeks require decoding video from the previous
keyframe up to the target position and so can take some time
depending on decoding performance. For some video formats
precise seeks are disabled. This option selects the default
choice to use for seeks; it's possible to explicitly override
that default in the definition of key bindings and in slave mode
commands.
off Never use precise seeks.
absolute
Use precise seeks if the seek is to an absolute position
in the file, such as a chapter seek, but not for
relative seeks like the default behavior of arrow keys
(default).
always
Use precise seeks whenever possible.
-identify
Shorthand for -msglevel identify=4. Show file parameters in an
easily parseable format. Also prints more detailed information
about subtitle and audio track languages and IDs. In some cases
you can get more information by using -msglevel identify=6. For
example, for a DVD or Blu-ray it will list the chapters and time
length of each title, as well as a disk ID. Combine this with
-frames 0 to suppress all video output. The wrapper script
TOOLS/midentify.sh suppresses the other MPlayer output and
(hopefully) shellescapes the filenames.
-idle (also see -slave)
Makes MPlayer wait idly instead of quitting when there is no
file to play. Mostly useful in slave mode where MPlayer can be
controlled through input commands.
-input <commands>
This option can be used to configure certain parts of the input
system. Paths are relative to ~/.mplayer/.
NOTE: Autorepeat is currently only supported by joysticks.
Available commands are:
conf=<filename>
Specify input configuration file other than the default
~/.mplayer/input.conf. ~/.mplayer/<filename> is assumed
if no full path is given.
ar-dev=<device>
Device to be used for Apple IR Remote (default is
autodetected, Linux only).
ar-delay
Delay in milliseconds before we start to autorepeat a
key (0 to disable).
ar-rate
Number of key presses to generate per second on
autorepeat.
(no)default-bindings
Use the key bindings that MPlayer ships with by default.
keylist
Prints all keys that can be bound to commands.
cmdlist
Prints all commands that can be bound to keys.
js-dev
Specifies the joystick device to use (default: /dev/
input/js0).
file=<filename>
Read commands from the given file. Mostly useful with a
FIFO.
NOTE: When the given file is a FIFO MPlayer opens both
ends so you can do several 'echo "seek 10" > mp_pipe'
and the pipe will stay valid.
-key-fifo-size <2-65000>
Specify the size of the FIFO that buffers key events (default:
7). If it is too small some events may be lost. The main
disadvantage of setting it to a very large value is that if you
hold down a key triggering some particularly slow command then
the player may be unresponsive while it processes all the queued
commands.
-lircconf <filename> (LIRC only)
Specifies a configuration file for LIRC (default: ~/.lircrc).
-list-properties
Print a list of the available properties.
-loop <number>
Loops movie playback <number> times. 0 means forever.
-menu (OSD menu only)
Turn on OSD menu support.
-menu-cfg <filename> (OSD menu only)
Use an alternative menu.conf.
-menu-chroot <path> (OSD menu only)
Chroot the file selection menu to a specific location.
EXAMPLE:
-menu-chroot /home
Will restrict the file selection menu to /home and
downward (i.e. no access to / will be possible, but
/home/user_name will).
-menu-keepdir (OSD menu only)
File browser starts from the last known location instead of
current directory.
-menu-root <value> (OSD menu only)
Specify the main menu.
-menu-startup (OSD menu only)
Display the main menu at MPlayer startup.
-mouse-movements
Permit MPlayer to receive pointer events reported by the video
output driver. Necessary to select the buttons in DVD menus.
Supported for X11-based VOs (x11, xv, etc) and the gl, gl2,
direct3d and corevideo VOs.
-noar Turns off AppleIR remote support.
-noconsolecontrols
Prevent MPlayer from reading key events from standard input.
Useful when reading data from standard input. This is
automatically enabled when - is found on the command line.
There are situations where you have to set it manually, e.g. if
you open /dev/stdin (or the equivalent on your system), use
stdin in a playlist or intend to read from stdin later on via
the loadfile or loadlist slave commands.
-noinitial-audio-sync
When starting a video file or after events such as seeking
MPlayer will by default modify the audio stream to make it start
from the same timestamp as video, by either inserting silence at
the start or cutting away the first samples. This option
disables that functionality and makes the player behave like
older MPlayer versions did: video and audio are both started
immediately even if their start timestamps differ, and then
video timing is gradually adjusted if necessary to reach correct
synchronization later.
-nojoystick
Turns off joystick support.
-nolirc
Turns off LIRC support.
-nomouseinput
Disable mouse button press/release input (mozplayerxp's context
menu relies on this option).
-noordered-chapters
Disable support for Matroska ordered chapters. MPlayer will not
load or search for video segments from other files, and will
also ignore any chapter order specified for the main file.
-pts-association-mode auto|decode|sort
Select the method used to determine which container packet
timestamp corresponds to a particular output frame from the
video decoder. Normally you shouldn't need to change this
option.
auto Try to pick a working mode from the ones below
automatically (default)
decoder
Use decoder reordering functionality.
sort Maintain a buffer of unused pts values and use the
lowest value for the frame.
-rtc (RTC only)
Turns on usage of the Linux RTC (realtime clock - /dev/rtc) as
timing mechanism. This wakes up the process every 1/1024
seconds to check the current time. Useless with modern Linux
kernels configured for desktop use as they already wake up the
process with similar accuracy when using normal timed sleep.
-playing-msg <string>
Print out a string before starting playback. The following
expansions are supported:
${NAME}
Expand to the value of the property NAME.
?(NAME:TEXT)
Expand TEXT only if the property NAME is available.
?(!NAME:TEXT)
Expand TEXT only if the property NAME is not available.
-playlist <filename>
Play files according to a playlist file (ASX, Winamp, SMIL, or
one-file-per-line format).
WARNING: The way MPlayer parses and uses playlist files is not
safe against maliciously constructed files. Such files may
trigger harmful actions. This has been the case for all MPlayer
versions, but unfortunately this fact was not well documented
earlier, and some people have even misguidedly recommended use
of -playlist with untrusted sources. Do NOT use -playlist with
random internet sources or files you don't trust!
NOTE: This option is considered an entry so options found after
it will apply only to the elements of this playlist.
FIXME: This needs to be clarified and documented thoroughly.
-rtc-device <device>
Use the specified device for RTC timing.
-shuffle
Play files in random order.
-slave (also see -input)
Switches on slave mode, in which MPlayer works as a backend for
other programs. Instead of intercepting keyboard events,
MPlayer will read commands separated by a newline (\n) from
stdin.
NOTE: See -input cmdlist for a list of slave commands and
DOCS/tech/slave.txt for their description. Also, this is not
intended to disable other inputs, e.g. via the video window, use
some other method like -input nodefault-bindings:conf=/dev/null
for that.
-softsleep
Time frames by repeatedly checking the current time instead of
asking the kernel to wake up MPlayer at the correct time.
Useful if your kernel timing is imprecise and you cannot use the
RTC either. Comes at the price of higher CPU consumption.
-sstep <sec>
Skip <sec> seconds after every frame. The normal framerate of
the movie is kept, so playback is accelerated. Since MPlayer
can only seek to the next keyframe this may be inexact.
DEMUXER/STREAM OPTIONS
-a52drc <level>
Select the Dynamic Range Compression level for AC-3 audio
streams. <level> is a float value ranging from 0 to 1, where 0
means no compression and 1 (which is the default) means full
compression (make loud passages more silent and vice versa).
Values up to 2 are also accepted, but are purely experimental.
This option only shows an effect if the AC-3 stream contains the
required range compression information.
-aid <ID> (also see -alang)
Select audio channel (MPEG: 0-31, AVI/OGM: 1-99, ASF/RM: 0-127,
VOB(AC-3): 128-159, VOB(LPCM): 160-191, MPEG-TS 17-8190).
MPlayer prints the available audio IDs when run in verbose (-v)
mode. When playing an MPEG-TS stream, MPlayer will use the
first program (if present) with the chosen audio stream.
-ausid <ID> (also see -alang)
Select audio substream channel. Currently the valid range is
0x55..0x75 and applies only to MPEG-TS when handled by the
native demuxer (not by libavformat). The format type may not be
correctly identified because of how this information (or lack
thereof) is embedded in the stream, but it will demux correctly
the audio streams when multiple substreams are present. MPlayer
prints the available substream IDs when run with -identify.
-alang <language code[,language code,...]> (also see -aid)
Specify a priority list of audio languages to use. Different
container formats employ different language codes. DVDs use ISO
639-1 two letter language codes, Matroska, MPEG-TS and NUT use
ISO 639-2 three letter language codes while OGM uses a free-form
identifier. MPlayer prints the available languages when run in
verbose (-v) mode.
EXAMPLE:
mplayer dvd://1 -alang hu,en
Chooses the Hungarian language track on a DVD and falls
back on English if Hungarian is not available.
mplayer -alang jpn example.mkv
Plays a Matroska file in Japanese.
-audio-demuxer <[+]name> (-audiofile only)
Force audio demuxer type for -audiofile. Use a '+' before the
name to force it, this will skip some checks! Give the demuxer
name as printed by -audio-demuxer help. -audio-demuxer audio
forces MP3.
-audiofile <filename>
Play audio from an external file (WAV, MP3 or Ogg Vorbis) while
viewing a movie.
-audiofile-cache <kBytes>
Enables caching for the stream used by -audiofile, using the
specified amount of memory.
-reuse-socket (udp:// only)
Allows a socket to be reused by other processes as soon as it is
closed.
-bandwidth <Bytes> (network only)
Specify the maximum bandwidth for network streaming (for servers
that are able to send content in different bitrates). Useful if
you want to watch live streamed media behind a slow connection.
With Real RTSP streaming, it is also used to set the maximum
delivery bandwidth allowing faster cache filling and stream
dumping.
-bluray-angle <angle ID> (Blu-ray only)
Some Blu-ray discs contain scenes that can be viewed from
multiple angles. Here you can tell MPlayer which angles to use
(default: 1).
-bluray-chapter <chapter ID> (Blu-ray only)
Tells MPlayer which Blu-ray chapter to start the current title
from (default: 1).
-bluray-device <path to disc> (Blu-ray only)
Specify the Blu-ray disc location. Must be a directory with
Blu-ray structure.
-cache <kBytes>
This option specifies how much memory (in kBytes) to use when
precaching a file or URL. Especially useful on slow media.
-nocache
Turns off caching.
-cache-min <percentage>
Playback will start when the cache has been filled up to
<percentage> of the total.
-cache-seek-min <percentage>
If a seek is to be made to a position within <percentage> of the
cache size from the current position, MPlayer will wait for the
cache to be filled to this position rather than performing a
stream seek (default: 50).
-capture
Allows capturing the primary stream (not additional audio tracks
or other kind of streams) into the file specified by -dumpfile
or by default. If this option is given, capturing can be
started and stopped by pressing the key bound to this function
(see section INTERACTIVE CONTROL). Same as for -dumpstream,
this will likely not produce usable results for anything else
than MPEG streams. Note that, due to cache latencies, captured
data may begin and end somewhat delayed compared to what you see
displayed.
-cdda <option1:option2> (CDDA only)
This option can be used to tune the CD Audio reading feature of
MPlayer.
Available options are:
speed=<value>
Set CD spin speed.
paranoia=<0-2>
Set paranoia level. Values other than 0 seem to break
playback of anything but the first track.
0: disable checking (default)
1: overlap checking only
2: full data correction and verification
generic-dev=<value>
Use specified generic SCSI device.
sector-size=<value>
Set atomic read size.
overlap=<value>
Force minimum overlap search during verification to
<value> sectors.
toc-bias
Assume that the beginning offset of track 1 as reported
in the TOC will be addressed as LBA 0. Some Toshiba
drives need this for getting track boundaries correct.
toc-offset=<value>
Add <value> sectors to the values reported when
addressing tracks. May be negative.
(no)skip
(Never) accept imperfect data reconstruction.
-cdrom-device <path to device>
Specify the CD-ROM device (default: /dev/cdrom).
-channels <number> (also see -af channels)
Request the number of playback channels (default: 2). MPlayer
asks the decoder to decode the audio into as many channels as
specified. Then it is up to the decoder to fulfill the
requirement. This is usually only important when playing videos
with AC-3 audio (like DVDs). In that case liba52 does the
decoding by default and correctly downmixes the audio into the
requested number of channels. To directly control the number of
output channels independently of how many channels are decoded,
use the channels filter.
NOTE: This option is honored by codecs (AC-3 only), filters
(surround) and audio output drivers (OSS at least).
Available options are:
2 stereo
4 surround
6 full 5.1
8 full 7.1
-chapter <chapter ID>[-<endchapter ID>] (dvd:// and dvdnav:// only)
Specify which chapter to start playing at. Optionally specify
which chapter to end playing at (default: 1).
-edition <edition ID> (Matroska only)
Specify the edition (set of chapters) to use, where 0 is the
first. If set to -1 (the default), MPlayer will choose the first
edition declared as a default, or if there is no default, the
first edition defined.
-cookies (network only)
Send cookies when making HTTP requests.
-cookies-file <filename> (network only)
Read HTTP cookies from <filename> (default: ~/.mozilla/ and
~/.netscape/) and skip reading from default locations. The file
is assumed to be in Netscape format.
-delay <sec>
audio delay in seconds (positive or negative float value)
Negative values delay the audio, and positive values delay the
video.
-ignore-start
Ignore the specified starting time for streams in AVI files.
This nullifies stream delays.
-demuxer <[+]name>
Force demuxer type. Use a '+' before the name to force it, this
will skip some checks! Give the demuxer name as printed by
-demuxer help.
-dumpaudio
Dumps raw compressed audio stream to ./stream.dump (useful with
MPEG/AC-3, in most other cases the resulting file will not be
playable). If you give more than one of -dumpaudio, -dumpvideo,
-dumpstream on the command line only the last one will work.
-dumpfile <filename>
Specify which file MPlayer should dump to. Should be used
together with -dumpaudio / -dumpvideo / -dumpstream / -capture.
-dumpstream
Dumps the raw stream to ./stream.dump. Useful when ripping from
DVD or network. If you give more than one of -dumpaudio,
-dumpvideo, -dumpstream on the command line only the last one
will work.
-dumpvideo
Dump raw compressed video stream to ./stream.dump (not very
usable). If you give more than one of -dumpaudio, -dumpvideo,
-dumpstream on the command line only the last one will work.
-dvbin <options> (DVB only)
Pass the following parameters to the DVB input module, in order
to override the default ones:
card=<1-4>
Specifies using card number 1-4 (default: 1).
file=<filename>
Instructs MPlayer to read the channels list from
<filename>. Default is ~/.mplayer/
channels.conf.{sat,ter,cbl,atsc} (based on your card
type) or ~/.mplayer/channels.conf as a last resort.
timeout=<1-30>
Maximum number of seconds to wait when trying to tune a
frequency before giving up (default: 30).
-dvd-device <path to device> (DVD only)
Specify the DVD device or .iso filename (default: /dev/dvd).
You can also specify a directory that contains files previously
copied directly from a DVD (with e.g. vobcopy).
-dvd-speed <factor or speed in KB/s> (DVD only)
Try to limit DVD speed (default: 0, no change). DVD base speed
is about 1350KB/s, so a 8x drive can read at speeds up to
10800KB/s. Slower speeds make the drive more quiet, for
watching DVDs 2700KB/s should be quiet and fast enough. MPlayer
resets the speed to the drive default value on close. Values
less than 100 mean multiples of 1350KB/s, i.e. -dvd-speed 8
selects 10800KB/s.
NOTE: You need write access to the DVD device to change the
speed.
-dvdangle <angle ID> (DVD only)
Some DVD discs contain scenes that can be viewed from multiple
angles. Here you can tell MPlayer which angles to use (default:
1).
-edl <filename>
Enables edit decision list (EDL) actions during playback. Video
will be skipped over and audio will be muted and unmuted
according to the entries in the given file. See
http://www.mplayerhq.hu/DOCS/HTML/en/edl.html for details on how
to use this.
-endpos <[[hh:]mm:]ss[.ms]> (also see -ss and -sb)
Stop at given time.
NOTE: When used in conjunction with -ss option, -endpos time
will shift forward by seconds specified with -ss.
EXAMPLE:
-endpos 56
Stop at 56 seconds.
-endpos 01:10:00
Stop at 1 hour 10 minutes.
-ss 10 -endpos 56
Stop at 1 minute 6 seconds.
-forceidx
Force index rebuilding. Useful for files with broken index (A/V
desync, etc). This will enable seeking in files where seeking
was not possible.
NOTE: This option only works if the underlying media supports
seeking (i.e. not with stdin, pipe, etc).
-fps <float value>
Override video framerate. Useful if the original value is wrong
or missing.
-frames <number>
Play/convert only first <number> frames, then quit.
-hr-mp3-seek (MP3 only)
Hi-res MP3 seeking. Enabled when playing from an external MP3
file, as we need to seek to the very exact position to keep A/V
sync. Can be slow especially when seeking backwards since it
has to rewind to the beginning to find an exact frame position.
-http-header-fields <field1,field2>
Set custom HTTP fields when accessing HTTP stream.
EXAMPLE:
mplayer -http-header-fields 'Field1: value1','Field2:
value2' http://localhost:1234
Will generate HTTP request:
GET / HTTP/1.0
Host: localhost:1234
User-Agent: MPlayer
Icy-MetaData: 1
Field1: value1
Field2: value2
Connection: close
-idx (also see -forceidx)
Rebuilds index of files if no index was found, allowing seeking.
Useful with broken/incomplete downloads, or badly created files.
NOTE: This option only works if the underlying media supports
seeking (i.e. not with stdin, pipe, etc).
-noidx Skip rebuilding index file.
-ipv4-only-proxy (network only)
Skip the proxy for IPv6 addresses. It will still be used for
IPv4 connections.
-lavfdopts <option1:option2:...>
Specify parameters for libavformat demuxers (-demuxer lavf).
Separate multiple options with a colon.
Available suboptions are:
analyzeduration=<value>
Maximum length in seconds to analyze the stream
properties.
format=<value>
Force a specific libavformat demuxer.
o=<key>=<value>[,<key>=<value>[,...]]
Pass AVOptions to libavformat demuxer. Note, a patch to
make the o= unneeded and pass all unknown options
through the AVOption system is welcome. A full list of
AVOptions can be found in the FFmpeg manual. Note that
some options may conflict with MPlayer options.
EXAMPLE:
o=fflags=+ignidx
probesize=<value>
Maximum amount of data to probe during the detection
phase. In the case of MPEG-TS this value identifies the
maximum number of TS packets to scan.
cryptokey=<hexstring>
Encryption key the demuxer should use. This is the raw
binary data of the key converted to a hexadecimal
string.
-loadidx <index file>
The file from which to read the video index data saved by
-saveidx. This index will be used for seeking, overriding any
index data contained in the AVI itself. MPlayer will not
prevent you from loading an index file generated from a
different AVI, but this is sure to cause unfavorable results.
NOTE: This option is obsolete now that MPlayer has OpenDML
support.
-mc <seconds/frame>
maximum A-V sync correction per frame (in seconds)
-mf <option1:option2:...>
Used when decoding from multiple PNG or JPEG files.
Available options are:
w=<value>
input file width (default: autodetect)
h=<value>
input file height (default: autodetect)
fps=<value>
output fps (default: 25)
type=<value>
input file type (available: jpeg, png, tga, sgi)
-ni (AVI only)
Force usage of non-interleaved AVI parser (fixes playback of
some bad AVI files).
-nobps (AVI only)
Do not use average byte/second value for A-V sync. Helps with
some AVI files with broken header.
-noextbased
Disables extension-based demuxer selection. By default, when
the file type (demuxer) cannot be detected reliably (the file
has no header or it is not reliable enough), the filename
extension is used to select the demuxer. Always falls back on
content-based demuxer selection.
-passwd <password> (also see -user) (network only)
Specify password for HTTP authentication.
-prefer-ipv4 (network only)
Use IPv4 on network connections. Falls back on IPv6
automatically.
-prefer-ipv6 (IPv6 network only)
Use IPv6 on network connections. Falls back on IPv4
automatically.
-psprobe <byte position>
When playing an MPEG-PS or MPEG-PES streams, this option lets
you specify how many bytes in the stream you want MPlayer to
scan in order to identify the video codec used. This option is
needed to play EVO or VDR files containing H.264 streams.
-pvr <option1:option2:...> (PVR only)
This option tunes various encoding properties of the PVR capture
module. It has to be used with any hardware MPEG encoder based
card supported by the V4L2 driver. The Hauppauge WinTV
PVR-150/250/350/500 and all IVTV based cards are known as PVR
capture cards. Be aware that only Linux 2.6.18 kernel and above
is able to handle MPEG stream through V4L2 layer. For hardware
capture of an MPEG stream and watching it with MPlayer, use
'pvr://' as a movie URL.
Available options are:
aspect=<0-3>
Specify input aspect ratio:
0: 1:1
1: 4:3 (default)
2: 16:9
3: 2.21:1
arate=<32000-48000>
Specify encoding audio rate (default: 48000 Hz,
available: 32000, 44100 and 48000 Hz).
alayer=<1-3>
Specify MPEG audio layer encoding (default: 2).
abitrate=<32-448>
Specify audio encoding bitrate in kbps (default: 384).
amode=<value>
Specify audio encoding mode. Available preset values
are 'stereo', 'joint_stereo', 'dual' and 'mono'
(default: stereo).
vbitrate=<value>
Specify average video bitrate encoding in Mbps (default:
6).
vmode=<value>
Specify video encoding mode:
vbr: Variable BitRate (default)
cbr: Constant BitRate
vpeak=<value>
Specify peak video bitrate encoding in Mbps (only useful
for VBR encoding, default: 9.6).
fmt=<value>
Choose an MPEG format for encoding:
ps: MPEG-2 Program Stream (default)
ts: MPEG-2 Transport Stream
mpeg1: MPEG-1 System Stream
vcd: Video CD compatible stream
svcd: Super Video CD compatible stream
dvd: DVD compatible stream
-radio <option1:option2:...> (radio only)
These options set various parameters of the radio capture
module. For listening to radio with MPlayer use
'radio://<frequency>' (if channels option is not given) or
'radio://<channel_number>' (if channels option is given) as a
movie URL. You can see allowed frequency range by running
MPlayer with '-v'. To start the grabbing subsystem, use
'radio://<frequency or channel>/capture'. If the capture
keyword is not given you can listen to radio using the line-in
cable only. Using capture to listen is not recommended due to
synchronization problems, which makes this process
uncomfortable.
Available options are:
device=<value>
Radio device to use (default: /dev/radio0 for Linux and
/dev/tuner0 for *BSD).
driver=<value>
Radio driver to use (default: v4l2 if available,
otherwise v4l). Currently, v4l and v4l2 drivers are
supported.
volume=<0..100>
sound volume for radio device (default 100)
freq_min=<value> (*BSD BT848 only)
minimum allowed frequency (default: 87.50)
freq_max=<value> (*BSD BT848 only)
maximum allowed frequency (default: 108.00)
channels=<frequency>-<name>,<frequency>-<name>,...
Set channel list. Use _ for spaces in names (or play
with quoting ;-). The channel names will then be
written using OSD and the slave commands
radio_step_channel and radio_set_channel will be usable
for a remote control (see LIRC). If given, number in
movie URL will be treated as channel position in channel
list.
EXAMPLE: radio://1, radio://104.4, radio_set_channel 1
adevice=<value> (radio capture only)
Name of device to capture sound from. Without such a
name capture will be disabled, even if the capture
keyword appears in the URL. For ALSA devices use it in
the form hw=<card>.<device>. If the device name
contains a '=', the module will use ALSA to capture,
otherwise OSS.
arate=<value> (radio capture only)
Rate in samples per second (default: 44100).
NOTE: When using audio capture set also -rawaudio
rate=<value> option with the same value as arate. If
you have problems with sound speed (runs too quickly),
try to play with different rate values (e.g.
48000,44100,32000,...).
achannels=<value> (radio capture only)
Number of audio channels to capture.
-rawaudio <option1:option2:...>
This option lets you play raw audio files. You have to use
-demuxer rawaudio as well. It may also be used to play audio
CDs which are not 44kHz 16-bit stereo. For playing raw AC-3
streams use -rawaudio format=0x2000 -demuxer rawaudio.
Available options are:
channels=<value>
number of channels
rate=<value>
rate in samples per second
samplesize=<value>
sample size in bytes
bitrate=<value>
bitrate for rawaudio files
format=<value>
fourcc in hex
-rawvideo <option1:option2:...>
This option lets you play raw video files. You have to use
-demuxer rawvideo as well.
Available options are:
fps=<value>
rate in frames per second (default: 25.0)
sqcif|qcif|cif|4cif|pal|ntsc
set standard image size
w=<value>
image width in pixels
h=<value>
image height in pixels
i420|yv12|yuy2|y8
set colorspace
format=<value>
colorspace (fourcc) in hex or string constant. Use
-rawvideo format=help for a list of possible strings.
size=<value>
frame size in Bytes
EXAMPLE:
mplayer foreman.qcif -demuxer rawvideo -rawvideo qcif
Play the famous "foreman" sample video.
mplayer sample-720x576.yuv -demuxer rawvideo -rawvideo
w=720:h=576
Play a raw YUV sample.
-referrer <string> (network only)
Specify a referrer path or URL for HTTP requests.
-rtsp-port
Used with 'rtsp://' URLs to force the client's port number.
This option may be useful if you are behind a router and want to
forward the RTSP stream from the server to a specific client.
-rtsp-destination
Used with 'rtsp://' URLs to force the destination IP address to
be bound. This option may be useful with some RTSP server which
do not send RTP packets to the right interface. If the
connection to the RTSP server fails, use -v to see which IP
address MPlayer tries to bind to and try to force it to one
assigned to your computer instead.
-rtsp-stream-over-tcp (LIVE555 and NEMESI only)
Used with 'rtsp://' URLs to specify that the resulting incoming
RTP and RTCP packets be streamed over TCP (using the same TCP
connection as RTSP). This option may be useful if you have a
broken internet connection that does not pass incoming UDP
packets (see http://www.live555.com/mplayer/).
-rtsp-stream-over-http (LIVE555 only)
Used with 'http://' URLs to specify that the resulting incoming
RTP and RTCP packets be streamed over HTTP.
-saveidx <filename>
Force index rebuilding and dump the index to <filename>.
Currently this only works with AVI files.
NOTE: This option is obsolete now that MPlayer has OpenDML
support.
-sb <byte position> (also see -ss)
Seek to byte position. Useful for playback from CD-ROM images
or VOB files with junk at the beginning.
-speed <0.01-100>
Slow down or speed up playback by the factor given as parameter.
-srate <Hz>
Select the output sample rate to be used (of course sound cards
have limits on this). If the sample frequency selected is
different from that of the current media, the resample or
lavcresample audio filter will be inserted into the audio filter
layer to compensate for the difference. The type of resampling
can be controlled by the -af-adv option. The default is fast
resampling that may cause distortion.
-ss <time> (also see -sb)
Seek to given time position.
EXAMPLE:
-ss 56
Seeks to 56 seconds.
-ss 01:10:00
Seeks to 1 hour 10 min.
-tskeepbroken
Tells MPlayer not to discard TS packets reported as broken in
the stream. Sometimes needed to play corrupted MPEG-TS files.
-tsprobe <byte position>
When playing an MPEG-TS stream, this option lets you specify how
many bytes in the stream you want MPlayer to search for the
desired audio and video IDs.
-tsprog <1-65534>
When playing an MPEG-TS stream, you can specify with this option
which program (if present) you want to play. Can be used with
-vid and -aid.
-tv <option1:option2:...> (TV/PVR only)
This option tunes various properties of the TV capture module.
For watching TV with MPlayer, use 'tv://' or
'tv://<channel_number>' or even 'tv://<channel_name> (see option
channels for channel_name below) as a movie URL. You can also
use 'tv:///<input_id>' to start watching a movie from a
composite or S-Video input (see option input for details).
Available options are:
noaudio
no sound
automute=<0-255> (v4l and v4l2 only)
If signal strength reported by device is less than this
value, audio and video will be muted. In most cases
automute=100 will be enough. Default is 0 (automute
disabled).
driver=<value>
See -tv driver=help for a list of compiled-in TV input
drivers. available: dummy, v4l, v4l2, bsdbt848
(default: autodetect)
device=<value>
Specify TV device (default: /dev/video0). NOTE: For the
bsdbt848 driver you can provide both bktr and tuner
device names separating them with a comma, tuner after
bktr (e.g. -tv device=/dev/bktr1,/dev/tuner1).
input=<value>
Specify input (default: 0 (TV), see console output for
available inputs).
freq=<value>
Specify the frequency to set the tuner to (e.g.
511.250). Not compatible with the channels parameter.
outfmt=<value>
Specify the output format of the tuner with a preset
value supported by the V4L driver (yv12, rgb32, rgb24,
rgb16, rgb15, uyvy, yuy2, i420) or an arbitrary format
given as hex value. Try outfmt=help for a list of all
available formats.
width=<value>
output window width
height=<value>
output window height
fps=<value>
framerate at which to capture video (frames per second)
buffersize=<value>
maximum size of the capture buffer in megabytes
(default: dynamical)
norm=<value>
For bsdbt848 and v4l, PAL, SECAM, NTSC are available.
For v4l2, see the console output for a list of all
available norms, also see the normid option below.
normid=<value> (v4l2 only)
Sets the TV norm to the given numeric ID. The TV norm
depends on the capture card. See the console output for
a list of available TV norms.
channel=<value>
Set tuner to <value> channel.
chanlist=<value>
available: argentina, australia, china-bcast, europe-
east, europe-west, france, ireland, italy, japan-bcast,
japan-cable, newzealand, russia, southafrica, us-bcast,
us-cable, us-cable-hrc
channels=<chan>-<name>[=<norm>],<chan>-<name>[=<norm>],...
Set names for channels. NOTE: If <chan> is an integer
greater than 1000, it will be treated as frequency (in
kHz) rather than channel name from frequency table.
Use _ for spaces in names (or play with quoting ;-).
The channel names will then be written using OSD, and
the slave commands tv_step_channel, tv_set_channel and
tv_last_channel will be usable for a remote control (see
LIRC). Not compatible with the frequency parameter.
NOTE: The channel number will then be the position in
the 'channels' list, beginning with 1.
EXAMPLE: tv://1, tv://TV1, tv_set_channel 1,
tv_set_channel TV1
[brightness|contrast|hue|saturation]=<-100-100>
Set the image equalizer on the card.
audiorate=<value>
Set input audio sample rate.
forceaudio
Capture audio even if there are no audio sources
reported by v4l.
alsa
Capture from ALSA.
amode=<0-3>
Choose an audio mode:
0: mono
1: stereo
2: language 1
3: language 2
forcechan=<1-2>
By default, the count of recorded audio channels is
determined automatically by querying the audio mode from
the TV card. This option allows forcing stereo/mono
recording regardless of the amode option and the values
returned by v4l. This can be used for troubleshooting
when the TV card is unable to report the current audio
mode.
adevice=<value>
Set an audio device. <value> should be /dev/xxx for OSS
and a hardware ID for ALSA. You must replace any ':' by
a '.' in the hardware ID for ALSA.
audioid=<value>
Choose an audio output of the capture card, if it has
more than one.
[volume|bass|treble|balance]=<0-65535> (v4l1)
[volume|bass|treble|balance]=<0-100> (v4l2)
These options set parameters of the mixer on the video
capture card. They will have no effect, if your card
does not have one. For v4l2 50 maps to the default
value of the control, as reported by the driver.
gain=<0-100> (v4l2)
Set gain control for video devices (usually webcams) to
the desired value and switch off automatic control. A
value of 0 enables automatic control. If this option is
omitted, gain control will not be modified.
immediatemode=<bool>
A value of 0 means capture and buffer audio and video
together. A value of 1 (default) means to do video
capture only and let the audio go through a loopback
cable from the TV card to the sound card.
mjpeg
Use hardware MJPEG compression (if the card supports
it). When using this option, you do not need to specify
the width and height of the output window, because
MPlayer will determine it automatically from the
decimation value (see below).
decimation=<1|2|4>
choose the size of the picture that will be compressed
by hardware MJPEG compression:
1: full size
704x576 PAL
704x480 NTSC
2: medium size
352x288 PAL
352x240 NTSC
4: small size
176x144 PAL
176x120 NTSC
quality=<0-100>
Choose the quality of the JPEG compression (< 60
recommended for full size).
tdevice=<value>
Specify TV teletext device (example: /dev/vbi0)
(default: none).
tformat=<format>
Specify TV teletext display format (default: 0):
0: opaque
1: transparent
2: opaque with inverted colors
3: transparent with inverted colors
tpage=<100-899>
Specify initial TV teletext page number (default: 100).
tlang=<-1-127>
Specify default teletext language code (default: 0),
which will be used as primary language until a type 28
packet is received. Useful when the teletext system
uses a non-latin character set, but language codes are
not transmitted via teletext type 28 packets for some
reason. To see a list of supported language codes set
this option to -1.
hidden_video_renderer (dshow only)
Terminate stream with video renderer instead of Null
renderer (default: off). Will help if video freezes but
audio does not. NOTE: May not work with -vo directx and
-vf crop combination.
hidden_vp_renderer (dshow only)
Terminate VideoPort pin stream with video renderer
instead of removing it from the graph (default: off).
Useful if your card has a VideoPort pin and video is
choppy. NOTE: May not work with -vo directx and -vf
crop combination.
system_clock (dshow only)
Use the system clock as sync source instead of the
default graph clock (usually the clock from one of the
live sources in graph).
normalize_audio_chunks (dshow only)
Create audio chunks with a time length equal to video
frame time length (default: off). Some audio cards
create audio chunks about 0.5s in size, resulting in
choppy video when using immediatemode=0.
-tvscan <option1:option2:...> (TV only)
Tune the TV channel scanner. MPlayer will also print value for
"-tv channels=" option, including existing and just found
channels.
Available suboptions are:
autostart
Begin channel scanning immediately after startup
(default: disabled).
period=<0.1-2.0>
Specify delay in seconds before switching to next
channel (default: 0.5). Lower values will cause faster
scanning, but can detect inactive TV channels as active.
threshold=<1-100>
Threshold value for the signal strength (in percent), as
reported by the device (default: 50). A signal strength
higher than this value will indicate that the currently
scanning channel is active.
-user <username> (also see -passwd) (network only)
Specify username for HTTP authentication.
-user-agent <string>
Use <string> as user agent for HTTP streaming.
-vid <ID>
Select video channel (MPG: 0-15, ASF: 0-255, MPEG-TS: 17-8190).
When playing an MPEG-TS stream, MPlayer will use the first
program (if present) with the chosen video stream.
-vivo <suboption> (DEBUG CODE)
Force audio parameters for the VIVO demuxer (for debugging
purposes). FIXME: Document this.
OSD/SUBTITLE OPTIONS
NOTE: Also see -vf expand.
-ass, -noass (FreeType only)
Use libass to render all text subtitles. This enables support
for the native styling of SSA/ASS subtitles, and also support
for some styling features in other subtitle formats by
conversion to ASS markup. Enabled by default if the player was
compiled with libass support.
NOTE: Some of the other subtitle options were written for the
old non-libass subtitle rendering system and may not work the
same way or at all with libass rendering enabled.
-ass-border-color <value>
Sets the border (outline) color for text subtitles. The color
format is RRGGBBAA.
-ass-bottom-margin <value>
Adds a black band at the bottom of the frame. The SSA/ASS
renderer can place subtitles there (with -ass-use-margins).
-ass-color <value>
Sets the color for text subtitles. The color format is
RRGGBBAA.
-ass-font-scale <value>
Set the scale coefficient to be used for fonts in the SSA/ASS
renderer.
-ass-force-style <[Style.]Param=Value[,...]>
Override some style or script info parameters.
EXAMPLE:
-ass-force-style FontName=Arial,Default.Bold=1
-ass-force-style PlayResY=768
-ass-hinting <type>
Set hinting type. <type> can be:
0 no hinting
1 FreeType autohinter, light mode
2 FreeType autohinter, normal mode
3 font native hinter
0-3 + 4
The same, but hinting will only be performed if the OSD
is rendered at screen resolution and will therefore not
be scaled.
The default value is 5 (use light hinter for unscaled OSD and
no hinting otherwise).
-ass-line-spacing <value>
Set line spacing value for SSA/ASS renderer.
-ass-styles <filename>
Load all SSA/ASS styles found in the specified file and use them
for rendering text subtitles. The syntax of the file is exactly
like the [V4 Styles] / [V4+ Styles] section of SSA/ASS.
-ass-top-margin <value>
Adds a black band at the top of the frame. The SSA/ASS renderer
can place toptitles there (with -ass-use-margins).
-ass-use-margins
Enables placing toptitles and subtitles in black borders when
they are available.
-ass-vsfilter-aspect-compat
Stretch SSA/ASS subtitles when playing anamorphic videos for
compatibility with traditional VSFilter behavior. This switch
has no effect when the video is stored with square pixels.
The renderer historically most commonly used for the SSA/ASS
subtitle formats, VSFilter, had questionable behavior that
resulted in subtitles being stretched too if the video was
stored in anamorphic format that required scaling for display.
This behavior is usually undesirable and newer VSFilter versions
may behave differently. However, many existing scripts
compensate for the stretching by modifying things in the
opposite direction. Thus if such scripts are displayed
"correctly" they will not appear as intended. This switch
enables emulation of the old VSFilter behavior (undesirable but
expected by many existing scripts). Enabled by default.
-dumpjacosub
Convert the given subtitle (specified with the -sub option) to
the time-based JACOsub subtitle format. Creates a dumpsub.js
file in the current directory.
-dumpmicrodvdsub
Convert the given subtitle (specified with the -sub option) to
the MicroDVD subtitle format. Creates a dumpsub.sub file in the
current directory.
-dumpmpsub
Convert the given subtitle (specified with the -sub option) to
MPlayer's subtitle format, MPsub. Creates a dump.mpsub file in
the current directory.
-dumpsami
Convert the given subtitle (specified with the -sub option) to
the time-based SAMI subtitle format. Creates a dumpsub.smi file
in the current directory.
-dumpsrtsub
Convert the given subtitle (specified with the -sub option) to
the time-based SubViewer (SRT) subtitle format. Creates a
dumpsub.srt file in the current directory.
NOTE: Some broken hardware players choke on SRT subtitle files
with Unix line endings. If you are unlucky enough to have such
a box, pass your subtitle files through unix2dos or a similar
program to replace Unix line endings with DOS/Windows line
endings.
-dumpsub (BETA CODE)
Dumps the subtitle substream from VOB streams. Also see the
-dump*sub options.
-noembeddedfonts
Disables use of fonts embedded in Matroska containers and ASS
scripts (default: enabled). These fonts can be used for SSA/ASS
subtitle rendering (-ass option).
-ffactor <number>
Resample the font alphamap. Can be:
0 plain white fonts
0.75 very narrow black outline (default)
1 narrow black outline
10 bold black outline
-flip-hebrew (FriBiDi only)
Turns on flipping subtitles using FriBiDi.
-noflip-hebrew-commas
Change FriBiDi's assumptions about the placements of commas in
subtitles. Use this if commas in subtitles are shown at the
start of a sentence instead of at the end.
-font <path to font.desc file, path to font (FreeType), font pattern
(Fontconfig)>
Search for the OSD/SUB fonts in an alternative directory
(default for normal fonts: ~/.mplayer/font/font.desc, default
for FreeType fonts: ~/.mplayer/subfont.ttf).
NOTE: With FreeType, this option determines the path to the text
font file. With Fontconfig, this option determines the
Fontconfig font pattern.
EXAMPLE:
-font ~/.mplayer/arial-14/font.desc
-font ~/.mplayer/arialuni.ttf
-font 'Bitstream Vera Sans'
-font 'Bitstream Vera Sans:style=Bold'
-fontconfig, -nofontconfig (fontconfig only)
Enables the use of fontconfig managed fonts. Enabled by default.
-forcedsubsonly
Display only forced subtitles for the DVD subtitle stream
selected by e.g. -slang.
-fribidi-charset <charset name> (FriBiDi only)
Specifies the character set that will be passed to FriBiDi when
decoding non-UTF-8 subtitles (default: ISO8859-8).
-ifo <VOBsub IFO file>
Indicate the file that will be used to load palette and frame
size for VOBsub subtitles.
-noautosub
Turns off automatic subtitle file loading.
-osd-duration <time>
Set the duration of the OSD messages in ms (default: 1000).
-osd-fractions <0-2>
Set how fractions of seconds of the current timestamp are
printed on the OSD:
0 Do not display fractions (default).
1 Show the first two decimals.
2 Show approximate frame count within current second.
This frame count is not accurate but only an
approximation. For variable fps, the approximation is
known to be far off the correct frame count.
-osdlevel <0-3>
Specifies which mode the OSD should start in.
0 subtitles only
1 volume + seek (default)
2 volume + seek + timer + percentage
3 volume + seek + timer + percentage + total time
-overlapsub
Allows the next subtitle to be displayed while the current one
is still visible (default is to enable the support only for
specific formats).
-sid <ID> (also see -slang, -vobsubid)
Display the subtitle stream specified by <ID> (0-31). MPlayer
prints the available subtitle IDs when run in verbose (-v) mode.
If you cannot select one of the subtitles on a DVD, also try
-vobsubid.
-nosub Disables any otherwise auto-selected internal subtitles (as e.g.
the Matroska/mkv demuxer supports). Use -noautosub to disable
the loading of external subtitle files.
-slang <language code[,language code,...]> (also see -sid)
Specify a priority list of subtitle languages to use. Different
container formats employ different language codes. DVDs use ISO
639-1 two letter language codes, Matroska uses ISO 639-2 three
letter language codes while OGM uses a free-form identifier.
MPlayer prints the available languages when run in verbose (-v)
mode.
EXAMPLE:
mplayer dvd://1 -slang hu,en
Chooses the Hungarian subtitle track on a DVD and falls
back on English if Hungarian is not available.
mplayer -slang jpn example.mkv
Plays a Matroska file with Japanese subtitles.
-spuaa <mode>
Antialiasing/scaling mode for DVD/VOBsub. A value of 16 may be
added to <mode> in order to force scaling even when original and
scaled frame size already match. This can be employed to e.g.
smooth subtitles with gaussian blur. Available modes are:
0 none (fastest, very ugly)
1 approximate (broken?)
2 full (slow)
3 bilinear (default, fast and not too bad)
4 uses swscaler gaussian blur (looks very good)
-spualign <-1-2>
Specify how SPU (DVD/VOBsub) subtitles should be aligned.
-1 original position
0 Align at top (original behavior, default).
1 Align at center.
2 Align at bottom.
-spugauss <0.0-3.0>
Variance parameter of gaussian used by -spuaa 4. Higher means
more blur (default: 1.0).
-sub <subtitlefile1,subtitlefile2,...>
Use/display these subtitle files. Only one file can be
displayed at the same time.
-sub-bg-alpha <0-255>
Specify the alpha channel value for subtitles and OSD
backgrounds. Big values mean more transparency. 0 means
completely transparent.
-sub-bg-color <0-255>
Specify the color value for subtitles and OSD backgrounds.
Currently subtitles are grayscale so this value is equivalent to
the intensity of the color. 255 means white and 0 black.
-sub-demuxer <[+]name> (-subfile only) (BETA CODE)
Force subtitle demuxer type for -subfile. Use a '+' before the
name to force it, this will skip some checks! Give the demuxer
name as printed by -sub-demuxer help.
-sub-fuzziness <mode>
Adjust matching fuzziness when searching for subtitles:
0 exact match
1 Load all subs containing movie name.
2 Load all subs in the current and -sub-paths directories.
-sub-no-text-pp
Disables any kind of text post processing done after loading the
subtitles. Used for debug purposes.
-subalign <0-2>
Specify which edge of the subtitles should be aligned at the
height given by -subpos.
0 Align subtitle top edge (original behavior).
1 Align subtitle center.
2 Align subtitle bottom edge (default).
-subcc <1-4>
Display DVD Closed Caption (CC) subtitles from the specified
channel. These are not the VOB subtitles, these are special
ASCII subtitles for the hearing impaired encoded in the VOB
userdata stream on most region 1 DVDs. CC subtitles have not
been spotted on DVDs from other regions so far.
-subcp <codepage> (iconv only)
If your system supports iconv(3), you can use this option to
specify the subtitle codepage.
EXAMPLE:
-subcp latin2
-subcp cp1250
-subcp enca:<language>:<fallback codepage> (ENCA only)
You can specify your language using a two letter language code
to make ENCA detect the codepage automatically. If unsure,
enter anything and watch mplayer -v output for available
languages. Fallback codepage specifies the codepage to use,
when autodetection fails.
EXAMPLE:
-subcp enca:cs:latin2
Guess the encoding, assuming the subtitles are Czech,
fall back on latin 2, if the detection fails.
-subcp enca:pl:cp1250
Guess the encoding for Polish, fall back on cp1250.
-sub-paths <path1:path2:...>
Specify extra directories where to search for subtitles matching
the video. Multiple directories can be separated by ":" (";" on
Windows). Paths can be relative or absolute. Relative paths
are interpreted relative to video file directory.
EXAMPLE: Assuming that /path/to/movie/movie.avi is played and
-sub-paths sub:subtitles:/tmp/subs is specified, MPlayer
searches for subtitle files in these directories:
/path/to/movie/
/path/to/movie/sub/
/path/to/movie/subtitles/
/tmp/subs/
~/.mplayer/sub/
-subdelay <sec>
Delays subtitles by <sec> seconds. Can be negative.
-subfile <filename> (BETA CODE)
Currently useless. Same as -audiofile, but for subtitle streams
(OggDS?).
-subfont <path to font (FreeType), font pattern (Fontconfig)> (FreeType
only)
Sets the subtitle font (see -font). If no -subfont is given,
-font is used.
-subfont-autoscale <0-3> (FreeType only)
Sets the autoscale mode.
NOTE: 0 means that text scale and OSD scale are font heights in
points.
The mode can be:
0 no autoscale
1 proportional to movie height
2 proportional to movie width
3 proportional to movie diagonal (default)
-subfont-blur <0-8> (FreeType only)
Sets the font blur radius (default: 2).
-subfont-encoding <value> (FreeType only)
Sets the font encoding. When set to 'unicode', all the glyphs
from the font file will be rendered and unicode will be used
(default: unicode).
-subfont-osd-scale <0-100> (FreeType only)
Sets the autoscale coefficient of the OSD elements (default: 6).
-subfont-outline <0-8> (FreeType only)
Sets the font outline thickness (default: 2).
-subfont-text-scale <0-100> (FreeType only)
Sets the subtitle text autoscale coefficient as percentage of
the screen size (default: 5).
-subfps <rate>
Specify the framerate of the subtitle file (default: movie fps).
NOTE: <rate> > movie fps speeds the subtitles up for frame-based
subtitle files and slows them down for time-based ones.
-subpos <0-100> (useful with -vf expand)
Specify the position of subtitles on the screen. The value is
the vertical position of the subtitle in % of the screen height.
-subwidth <10-100>
Specify the maximum width of subtitles on the screen. Useful
for TV-out. The value is the width of the subtitle in % of the
screen width.
-noterm-osd
Disable the display of OSD messages on the console when no video
output is available.
-term-osd-esc <escape sequence>
Specify the escape sequence to use before writing an OSD message
on the console. The escape sequence should move the pointer to
the beginning of the line used for the OSD and clear it
(default: ^[[A\r^[[K).
-unicode
Tells MPlayer to handle the subtitle file as unicode.
-unrarexec <path to unrar executable> (not supported on MingW)
Specify the path to the unrar executable so MPlayer can use it
to access rar-compressed VOBsub files (default: not set, so the
feature is off). The path must include the executable's
filename, i.e. /usr/local/bin/unrar.
-utf8
Tells MPlayer to handle the subtitle file as UTF-8.
-vobsub <VOBsub file without extension>
Specify a VOBsub file to use for subtitles. Has to be the full
pathname without extension, i.e. without the '.idx', '.ifo' or
'.sub'.
-vobsubid <0-31>
Specify the VOBsub subtitle ID.
AUDIO OUTPUT OPTIONS
-abs <value> (-ao oss only) (OBSOLETE)
Override audio driver/card buffer size detection.
-format <format> (also see the format audio filter)
Select the sample format used for output from the audio filter
layer to the sound card. The values that <format> can adopt are
listed below in the description of the format audio filter.
-gapless-audio
Try to play consecutive audio files with no silence or
disruption at the point of file change. This feature is
implemented in a simple manner and relies on audio output device
buffering to continue playback while moving from one file to
another. If playback of the new file starts slowly, for example
because it's played from a remote network location or because
you have specified cache settings that require time for the
initial cache fill, then the buffered audio may run out before
playback of the new file can start.
-mixer <device>
Use a mixer device different from the default /dev/mixer. For
ALSA this is the mixer name.
-mixer-channel <mixer line>[,mixer index] (-ao oss and -ao alsa only)
This option will tell MPlayer to use a different channel for
controlling volume than the default PCM. Options for OSS
include vol, pcm, line. For a complete list of options look for
SOUND_DEVICE_NAMES in /usr/include/linux/soundcard.h. For ALSA
you can use the names e.g. alsamixer displays, like Master,
Line, PCM.
NOTE: ALSA mixer channel names followed by a number must be
specified in the <name,number> format, i.e. a channel labeled
'PCM 1' in alsamixer must be converted to PCM,1.
-softvol
Force the use of the software mixer, instead of using the sound
card mixer.
-softvol-max <10.0-10000.0>
Set the maximum amplification level in percent (default: 110).
A value of 200 will allow you to adjust the volume up to a
maximum of double the current level. With values below 100 the
initial volume (which is 100%) will be above the maximum, which
e.g. the OSD cannot display correctly.
-volstep <0-100>
Set the step size of mixer volume changes in percent of the
whole range (default: 3).
-volume <-1-100> (also see -af volume)
Set the startup volume in the mixer, either hardware or software
(if used with -softvol). A value of -1 (the default) will not
change the volume.
AUDIO OUTPUT DRIVERS
Audio output drivers are interfaces to different audio output
facilities. The syntax is:
-ao <driver1[:suboption1[=value]:...],driver2,...[,]>
Specify a priority list of audio output drivers to be used.
If the list has a trailing ',' MPlayer will fall back on drivers not
contained in the list. Suboptions are optional and can mostly be
omitted.
NOTE: See -ao help for a list of compiled-in audio output drivers.
EXAMPLE:
-ao alsa,oss,
Try the ALSA driver, then the OSS driver, then others.
-ao alsa:noblock:device=hw=0.3

a list of available cards when you run this option with -v.
Currently only works with the directx video output driver.
-bpp <depth>
Override the autodetected color depth. Only supported by the
fbdev, dga, svga, vesa video output drivers.
-border
Play movie with window border and decorations. Since this is on
by default, use -noborder to disable the standard window
decorations.
-brightness <-100-100>
Adjust the brightness of the video signal (default: 0). Not
supported by all video output drivers.
-contrast <-100-100>
Adjust the contrast of the video signal (default: 0). Not
supported by all video output drivers.
-display <name> (X11 only)
Specify the hostname and display number of the X server you want
to display on.
EXAMPLE:

location whenever there is a change in video parameters, video
stream or file. This used to be the default behavior.
Currently only affects X11 VOs.
-fs (also see -zoom)
Fullscreen playback (centers movie, and paints black bands
around it). Not supported by all video output drivers.
-fsmode-dontuse <0-31> (OBSOLETE, use the -fs option)
Try this option if you still experience fullscreen problems.
-fstype <type1,type2,...> (X11 only)
Specify a priority list of fullscreen modes to be used. You can
negate the modes by prefixing them with '-'. If you experience
problems like the fullscreen window being covered by other
windows try using a different order.
NOTE: See -fstype help for a full list of available modes.
The available types are:
above
Use the _NETWM_STATE_ABOVE hint if available.
below
Use the _NETWM_STATE_BELOW hint if available.
fullscreen
Use the _NETWM_STATE_FULLSCREEN hint if available.
layer
Use the _WIN_LAYER hint with the default layer.
layer=<0...15>
Use the _WIN_LAYER hint with the given layer number.
netwm
Force NETWM style.
none
Clear the list of modes; you can add modes to enable
afterward.
stays_on_top
Use _NETWM_STATE_STAYS_ON_TOP hint if available.
EXAMPLE:

Default order, will be used as a fallback if incorrect
or unsupported modes are specified.
-fullscreen
Fixes fullscreen switching on OpenBox 1.x.
-gamma <-100-100>
Adjust the gamma of the video signal (default: 0). Not
supported by all video output drivers.
-geometry x[%][:y[%]] or [WxH][+-x+-y]
Adjust where the output is on the screen initially. The x and y
specifications are in pixels measured from the top-left of the
screen to the top-left of the image being displayed, however if
a percentage sign is given after the argument it turns the value
into a percentage of the screen size in that direction. It also
supports the standard X11 -geometry option format, in which e.g.
+10-50 means "place 10 pixels from the left border and 50 pixels
from the lower border" and "--20+-10" means "place 20 pixels
beyond the right and 10 pixels beyond the top border". If an
external window is specified using the -wid option, then the x
and y coordinates are relative to the top-left corner of the
window rather than the screen. The coordinates are relative to
the screen given with -xineramascreen for the video output
drivers that fully support -xineramascreen (direct3d, gl, gl2,
vdpau, x11, xv, corevideo).
NOTE: May not be supported by some of the older VO drivers.
EXAMPLE:
50:40
Places the window at x=50, y=40.
50%:50%
Places the window in the middle of the screen.
100%
Places the window at the middle of the right edge of the
screen.
100%:100%
Places the window at the bottom right corner of the
screen.
-hue <-100-100>
Adjust the hue of the video signal (default: 0). You can get a
colored negative of the image with this option. Not supported
by all video output drivers.
-monitor-dotclock <range[,range,...]> (-vo fbdev and vesa only)
Specify the dotclock or pixelclock range of the monitor.
-monitor-hfreq <range[,range,...]> (-vo fbdev and vesa only)
Specify the horizontal frequency range of the monitor.
-monitor-vfreq <range[,range,...]> (-vo fbdev and vesa only)
Specify the vertical frequency range of the monitor.
-monitoraspect <ratio> (also see -aspect)
Set the aspect ratio of your monitor or TV screen. A value of 0
disables a previous setting (e.g. in the config file).
Overrides the -monitorpixelaspect setting if enabled.
EXAMPLE:
-monitoraspect 4:3 or 1.3333
-monitoraspect 16:9 or 1.7777
-monitorpixelaspect <ratio> (also see -aspect)
Set the aspect of a single pixel of your monitor or TV screen
(default: 1). A value of 1 means square pixels (correct for
(almost?) all LCDs).
-name (X11 only)
Set the window class name.
-nodouble
Disables double buffering, mostly for debugging purposes.
Double buffering fixes flicker by storing two frames in memory,
and displaying one while decoding another. It can affect OSD
negatively, but often removes OSD flickering.
-nograbpointer
Do not grab the mouse pointer after a video mode change (-vm).
Useful for multihead setups.
-nokeepaspect
Do not keep window aspect ratio when resizing windows. By
default MPlayer tries to keep the correct video aspect ratio by
instructing the window manager to maintain window aspect when
resizing, and by adding black bars if the window manager
nevertheless allows window shape to change. This option
disables window manager aspect hints and scales the video to
completely fill the window without regard for aspect ratio.
-ontop
Makes the player window stay on top of other windows. Supported
by video output drivers which use X11, except SDL, as well as
directx, corevideo, quartz, ggi and gl2.
-panscan <0.0-1.0>
Enables pan-and-scan functionality (cropping the sides of e.g. a
16:9 movie to make it fit a 4:3 display without black bands).
The range controls how much of the image is cropped. May not
work with all video output drivers.
NOTE: Values between -1 and 0 are allowed as well, but highly
experimental and may crash or worse. Use at your own risk!
-panscanrange <-19.0-99.0> (experimental)
Change the range of the pan-and-scan functionality (default: 1).
Positive values mean multiples of the default range. Negative
numbers mean you can zoom in up to a factor of -panscanrange+1.
E.g. -panscanrange -3 allows a zoom factor of up to 4. This
feature is experimental. Do not report bugs unless you are
using -vo gl.
-refreshrate <Hz>
Set the monitor refreshrate in Hz. Currently only supported by
-vo directx combined with the -vm option.
-rootwin
Play movie in the root window (desktop background). Desktop
background images may cover the movie window, though. May not
work with all video output drivers.
-saturation <-100-100>
Adjust the saturation of the video signal (default: 0). You can
get grayscale output with this option. Not supported by all
video output drivers.
-screenh <pixels>
Specify the screen height for video output drivers which do not
know the screen resolution like fbdev, x11 and TV-out.
-screenw <pixels>
Specify the screen width for video output drivers which do not
know the screen resolution like fbdev, x11 and TV-out.
-stop-xscreensaver (X11 only)
Turns off xscreensaver at startup and turns it on again on exit.
If your screensaver supports neither the XSS nor
XResetScreenSaver API please use -heartbeat-cmd instead.
-title (also see -use-filename-title)
Set the window title. Supported by X11-based video output
drivers.
-use-filename-title (also see -title)
Set the window title using the media filename, when not set with
-title. Supported by X11-based video output drivers.
-vm
Try to change to a different video mode. Supported by the dga,
x11, xv, sdl and directx video output drivers. If used with the
directx video output driver the -screenw, -screenh, -bpp and
-refreshrate options can be used to set the new display mode.
-vsync
Enables VBI for the vesa, dfbmga and svga video output drivers.
-wid <window ID> (X11, OpenGL and DirectX only)
This tells MPlayer to attach to an existing window. Useful to
embed MPlayer in a browser (e.g. the plugger extension). This
option fills the given window completely, thus aspect scaling,
panscan, etc are no longer handled by MPlayer but must be
managed by the application that created the window.
-xineramascreen <-2-...>
In Xinerama configurations (i.e. a single desktop that spans
across multiple displays) this option tells MPlayer which screen
to display the movie on. A value of -2 means fullscreen across
the whole virtual display (in this case Xinerama information is
completely ignored), -1 means fullscreen on the display the
window currently is on. The initial position set via the
-geometry option is relative to the specified screen. Will
usually only work with "-fstype -fullscreen" or "-fstype none".
This option is not suitable to only set the startup screen
(because it will always display on the given screen in
fullscreen mode), -geometry is the best that is available for
that purpose currently. Supported by at least the direct3d, gl,
gl2, x11, xv and corevideo video output drivers.
VIDEO OUTPUT DRIVERS
Video output drivers are interfaces to different video output
facilities. The syntax is:
-vo <driver1[:suboption1[=value]:...],driver2,...[,]>
Specify a priority list of video output drivers to be used.
If the list has a trailing ',' MPlayer will fall back on drivers not
contained in the list. Suboptions are optional and can mostly be
omitted.
NOTE: See -vo help for a list of compiled-in video output drivers.
EXAMPLE:
-vo xmga,xv,
Try the Matrox X11 driver, then the Xv driver, then
others.
-vo directx:noaccel
Uses the DirectX driver with acceleration features
turned off.
Available video output drivers are:
xv (X11 only)
Uses the XVideo extension of XFree86 4.x to enable hardware
accelerated playback. If you cannot use a hardware specific
driver, this is probably the best option. For information about
what colorkey is used and how it is drawn run MPlayer with -v
option and look out for the lines tagged with [xv common] at the
beginning.
adaptor=<number>
Select a specific XVideo adaptor (check xvinfo results).
port=<number>
Select a specific XVideo port.
ck=<cur|use|set>
Select the source from which the colorkey is taken
(default: cur).
cur The default takes the colorkey currently set in
Xv.
use Use but do not set the colorkey from MPlayer
(use -colorkey option to change it).
set Same as use but also sets the supplied colorkey.
ck-method=<man|bg|auto>
Sets the colorkey drawing method (default: man).
man Draw the colorkey manually (reduces flicker in
some cases).
bg Set the colorkey as window background.
auto Let Xv draw the colorkey.
x11 (X11 only)
Shared memory video output driver without hardware acceleration
that works whenever X11 is present.
xover (X11 only)
Adds X11 support to all overlay based video output drivers.
Currently only supported by tdfx_vid.
<vo_driver>
Select the driver to use as source to overlay on top of
X11.
vdpau (X11 only)
Uses the VDPAU interface to display and optionally also decode
video. Hardware decoding is used with -vc ffmpeg12vdpau,
ffwmv3vdpau, ffvc1vdpau, ffh264vdpau or ffodivxvdpau.
sharpen=<-1-1>
For positive values, apply a sharpening algorithm to the
video, for negative values a blurring algorithm
(default: 0).
denoise=<0-1>
Apply a noise reduction algorithm to the video (default:
0, no noise reduction).
deint=<-4-4>
Select deinterlacing mode (default: -3). Positive
values choose mode and enable deinterlacing.
Corresponding negative values select the same
deinterlacing mode, but do not enable deinterlacing on
startup (useful in configuration files to specify what
mode will be enabled by the "D" key). All modes respect
-field-dominance.
0 same as -3
1 Show only first field, similar to -vf field.
2 Bob deinterlacing, similar to -vf tfields=1.
3 motion adaptive temporal deinterlacing. May
lead to A/V desync with slow video hardware
and/or high resolution.
4 motion adaptive temporal deinterlacing with
edge-guided spatial interpolation. Needs fast
video hardware.
chroma-deint
Makes temporal deinterlacers operate both on luma and
chroma (default). Use nochroma-deint to solely use luma
and speed up advanced deinterlacing. Useful with slow
video memory.
pullup
Try to apply inverse telecine, needs motion adaptive
temporal deinterlacing.
colorspace=<0-3>
Select the color space for YUV to RGB conversion. In
general BT.601 should be used for standard definition
(SD) content and BT.709 for high definition (HD)
content. Using incorrect color space results in
slightly under or over saturated and shifted colors.
0 Guess the color space based on video resolution.
Video with width >= 1280 or height > 576 is
assumed to be HD and BT.709 color space will be
used.
1 Use ITU-R BT.601 color space (default).
2 Use ITU-R BT.709 color space.
3 Use SMPTE-240M color space.
hqscaling=<0-9>
0 Use default VDPAU scaling (default).
1-9 Apply high quality VDPAU scaling (needs capable
hardware).
studio
Output video in studio level RGB (16-235). This is what
TVs and video monitors generally expect. By default PC
level RGB (0-255) suitable for PC monitors is used.
Providing studio level output to a device expecting PC
level input results in grey blacks and dim whites, the
reverse in crushed blacks and whites.
fps=<number>
Override autodetected display refresh rate value (the
value is needed for framedrop to allow video playback
rates higher than display refresh rate, and for vsync-
aware frame timing adjustments). Default 0 means use
autodetected value. A positive value is interpreted as
a refresh rate in Hz and overrides the autodetected
value. A negative value disables all timing adjustment
and framedrop logic.
queuetime_windowed=<number>
queuetime_fs=<number>
Use VDPAU's presentation queue functionality to queue
future video frame changes at most this many
milliseconds in advance (default: 50). See below for
additional information.
output_surfaces=<2-15>
Allocate this many output surfaces to display video
frames (default: 3). See below for additional
information.
Using the VDPAU frame queueing functionality controlled by the
queuetime options makes MPlayer's frame flip timing less
sensitive to system CPU load and allows MPlayer to start
decoding the next frame(s) slightly earlier which can reduce
jitter caused by individual slow-to-decode frames. However the
NVIDIA graphics drivers can make other window behavior such as
window moves choppy if VDPAU is using the blit queue (mainly
happens if you have the composite extension enabled) and this
feature is active. If this happens on your system and it
bothers you then you can set the queuetime value to 0 to disable
this feature. The settings to use in windowed and fullscreen
mode are separate because there should be less reason to disable
this for fullscreen mode (as the driver issue shouldn't affect
the video itself).
You can queue more frames ahead by increasing the queuetime
values and the output_surfaces count (to ensure enough surfaces
to buffer video for a certain time ahead you need at least as
many surfaces as the video has frames during that time, plus
two). This could help make video smoother in some cases. The
main downsides are increased video RAM requirements for the
surfaces and laggier display response to user commands (display
changes only become visible some time after they're queued). The
graphics driver implementation may also have limits on the
length of maximum queuing time or number of queued surfaces that
work well or at all.
dga (X11 only)
Play video through the XFree86 Direct Graphics Access extension.
Considered obsolete.
sdl (SDL only, buggy/outdated)
Highly platform independent SDL (Simple Directmedia Layer)
library video output driver. Since SDL uses its own X11 layer,
MPlayer X11 options do not have any effect on SDL. Note that it
has several minor bugs (-vm/-novm is mostly ignored, -fs behaves
like -novm should, window is in top-left corner when returning
from fullscreen, panscan is not supported, ...).
driver=<driver>
Explicitly choose the SDL driver to use.
(no)forcexv
Use XVideo through the sdl video output driver (default:
forcexv).
(no)hwaccel
Use hardware accelerated scaler (default: hwaccel).
direct3d (Windows only) (BETA CODE!)
Video output driver that uses the Direct3D interface (useful for
Vista).
directx (Windows only)
Video output driver that uses the DirectX interface.
noaccel
Turns off hardware acceleration. Try this option if you
have display problems.
kva (OS/2 only)
Video output driver that uses the libkva interface.
snap Force SNAP mode.
wo Force WarpOverlay! mode.
dive Force DIVE mode.
(no)t23
Enable or disable workaround for T23 laptop (default:
disabled). Try to enable this option if your video card
supports upscaling only.
quartz (Mac OS X only)
Mac OS X Quartz video output driver. Under some circumstances,
it might be more efficient to force a packed YUV output format,
with e.g. -vf format=yuy2.
device_id=<number>
Choose the display device to use in fullscreen.
fs_res=<width>:<height>
Specify the fullscreen resolution (useful on slow
systems).
corevideo (Mac OS X 10.4 or 10.3.9 with QuickTime 7)
Mac OS X CoreVideo video output driver
device_id=<number>
Choose the display device to use for fullscreen or set
it to -1 to always use the same screen the video window
is on (default: -1 - auto).
shared_buffer
Write output to a shared memory buffer instead of
displaying it and try to open an existing NSConnection
for communication with a GUI.
buffer_name=<name>
Name of the shared buffer created with shm_open as well
as the name of the NSConnection MPlayer will try to open
(default: "mplayerosx"). Setting buffer_name implicitly
enables shared_buffer.
fbdev (Linux only)
Uses the kernel framebuffer to play video.
<device>
Explicitly choose the fbdev device name to use (e.g.
/dev/fb0).
fbdev2 (Linux only)
Uses the kernel framebuffer to play video, alternative
implementation.
<device>
Explicitly choose the fbdev device name to use (default:
/dev/fb0).
vesa
Very general video output driver that should work on any VESA
VBE 2.0 compatible card.
(no)dga
Turns DGA mode on or off (default: on).
neotv_pal
Activate the NeoMagic TV out and set it to PAL norm.
neotv_ntsc
Activate the NeoMagic TV out and set it to NTSC norm.
lvo:
Activate the Linux Video Overlay on top of VESA mode.
svga
Play video using the SVGA library.
<video mode>
Specify video mode to use. The mode can be given in a
<width>x<height>x<colors> format, e.g. 640x480x16M or be
a graphics mode number, e.g. 84.
bbosd
Draw OSD into black bands below the movie (slower).
native
Use only native drawing functions. This avoids direct
rendering, OSD and hardware acceleration.
retrace
Force frame switch on vertical retrace. Usable only
with -double. It has the same effect as the -vsync
option.
sq
Try to select a video mode with square pixels.
gl
OpenGL video output driver, simple version. Video size must be
smaller than the maximum texture size of your OpenGL
implementation. Intended to work even with the most basic
OpenGL implementations, but also makes use of newer extensions,
which allow support for more colorspaces and direct rendering.
For optimal speed try adding the options
-dr -noslices
The code performs very few checks, so if a feature does not
work, this might be because it is not supported by your
card/OpenGL implementation even if you do not get any error
message. Use glxinfo or a similar tool to display the supported
OpenGL extensions.
(no)ati-hack
ATI drivers may give a corrupted image when PBOs are
used (when using -dr or force-pbo). This option fixes
this, at the expense of using a bit more memory.
(no)force-pbo
Always uses PBOs to transfer textures even if this
involves an extra copy. Currently this gives a little
extra speed with NVidia drivers and a lot more speed
with ATI drivers. May need -noslices and the ati-hack
suboption to work correctly.
(no)scaled-osd
Changes the way the OSD behaves when the size of the
window changes (default: disabled). When enabled
behaves more like the other video output drivers, which
is better for fixed-size fonts. Disabled looks much
better with FreeType fonts and uses the borders in
fullscreen mode. Does not work correctly with ass
subtitles (see -ass), you can instead render them
without OpenGL support via -vf ass.
osdcolor=<0xAARRGGBB>
Color for OSD (default: 0x00ffffff, corresponds to non-
transparent white).
rectangle=<0,1,2>
Select usage of rectangular textures which saves video
RAM, but often is slower (default: 0).
0: Use power-of-two textures (default).
1: Use the GL_ARB_texture_rectangle extension.
2: Use the GL_ARB_texture_non_power_of_two extension.
In some cases only supported in software and thus
very slow.
swapinterval=<n>
Minimum interval between two buffer swaps, counted in
displayed frames (default: 1). 1 is equivalent to
enabling VSYNC, 0 to disabling VSYNC. Values below 0
will leave it at the system default. This limits the
framerate to (horizontal refresh rate / n). Requires
GLX_SGI_swap_control support to work. With some
(most/all?) implementations this only works in
fullscreen mode.
ycbcr
Use the GL_MESA_ycbcr_texture extension to convert YUV
to RGB. In most cases this is probably slower than
doing software conversion to RGB.
yuv=<n>
Select the type of YUV to RGB conversion. The default
is auto-detection deciding between values 0 and 2.
0: Use software conversion. Compatible with all
OpenGL versions. Provides brightness, contrast and
saturation control.
1: Use register combiners. This uses an nVidia-
specific extension (GL_NV_register_combiners). At
least three texture units are needed. Provides
saturation and hue control. This method is fast but
inexact.
2: Use a fragment program. Needs the
GL_ARB_fragment_program extension and at least three
texture units. Provides brightness, contrast,
saturation and hue control.
3: Use a fragment program using the POW instruction.
Needs the GL_ARB_fragment_program extension and at
least three texture units. Provides brightness,
contrast, saturation, hue and gamma control. Gamma
can also be set independently for red, green and
blue. Method 4 is usually faster.
4: Use a fragment program with additional lookup.
Needs the GL_ARB_fragment_program extension and at
least four texture units. Provides brightness,
contrast, saturation, hue and gamma control. Gamma
can also be set independently for red, green and
blue.
5: Use ATI-specific method (for older cards). This
uses an ATI-specific extension
(GL_ATI_fragment_shader - not
GL_ARB_fragment_shader!). At least three texture
units are needed. Provides saturation and hue
control. This method is fast but inexact.
6: Use a 3D texture to do conversion via lookup.
Needs the GL_ARB_fragment_program extension and at
least four texture units. Extremely slow (software
emulation) on some (all?) ATI cards since it uses a
texture with border pixels. Provides brightness,
contrast, saturation, hue and gamma control. Gamma
can also be set independently for red, green and
blue. Speed depends more on GPU memory bandwidth
than other methods.
colorspace
Select the color space for YUV to RGB conversion.
0 Use the formula used normally by MPlayer
(default).
1 Use ITU-R BT.601 color space.
2 Use ITU-R BT.709 color space.
3 Use SMPTE-240M color space.
levelconv=<n>
Select the brightness level conversion to use for the
YUV to RGB conversion
0 Convert TV to PC levels (default).
1 Convert PC to TV levels.
2 Do not do any conversion.
lscale=<n>
Select the scaling function to use for luminance
scaling. Only valid for yuv modes 2, 3, 4 and 6.
0 Use simple linear filtering (default).
1 Use bicubic B-spline filtering (better quality).
Needs one additional texture unit. Older cards
will not be able to handle this for chroma at
least in fullscreen mode.
2 Use cubic filtering in horizontal, linear
filtering in vertical direction. Works on a few
more cards than method 1.
3 Same as 1 but does not use a lookup texture.
Might be faster on some cards.
4 Use experimental unsharp masking with 3x3
support and a default strength of 0.5 (see
filter-strength).
5 Use experimental unsharp masking with 5x5
support and a default strength of 0.5 (see
filter-strength).
cscale=<n>
Select the scaling function to use for chrominance
scaling. For details see lscale.
filter-strength=<value>
Set the effect strength for the lscale/cscale filters
that support it.
stereo=<value>
Select a method for stereo display. You may have to use
-aspect to fix the aspect value. Experimental, do not
expect too much from it.
0 normal 2D display
1 Convert side by side input to full-color red-
cyan stereo.
2 Convert side by side input to full-color green-
magenta stereo.
3 Convert side by side input to quadbuffered
stereo. Only supported by very few OpenGL
cards.
The following options are only useful if writing your own
fragment programs.
customprog=<filename>
Load a custom fragment program from <filename>. See
TOOLS/edgedect.fp for an example.
customtex=<filename>
Load a custom "gamma ramp" texture from <filename>.
This can be used in combination with yuv=4 or with the
customprog option.
(no)customtlin
If enabled (default) use GL_LINEAR interpolation,
otherwise use GL_NEAREST for customtex texture.
(no)customtrect
If enabled, use texture_rectangle for customtex texture.
Default is disabled.
(no)mipmapgen
If enabled, mipmaps for the video are automatically
generated. This should be useful together with the
customprog and the TXB instruction to implement blur
filters with a large radius. For most OpenGL
implementations this is very slow for any non-RGB
formats. Default is disabled.
Normally there is no reason to use the following options, they
mostly exist for testing purposes.
(no)glfinish
Call glFinish() before swapping buffers. Slower but in
some cases more correct output (default: disabled).
(no)manyfmts
Enables support for more (RGB and BGR) color formats
(default: enabled). Needs OpenGL version >= 1.2.
slice-height=<0-...>
Number of lines copied to texture in one piece (default:
0). 0 for whole image.
NOTE: If YUV colorspace is used (see yuv suboption),
special rules apply:
If the decoder uses slice rendering (see -noslices),
this setting has no effect, the size of the slices as
provided by the decoder is used.
If the decoder does not use slice rendering, the
default is 16.
(no)osd
Enable or disable support for OSD rendering via OpenGL
(default: enabled). This option is for testing; to
disable the OSD use -osdlevel 0 instead.
(no)aspect
Enable or disable aspect scaling and pan-and-scan
support (default: enabled). Disabling might increase
speed.
gl2
Variant of the OpenGL video output driver. Supports videos
larger than the maximum texture size but lacks many of the
advanced features and optimizations of the gl driver and is
unlikely to be extended further.
(no)glfinish
same as gl (default: enabled)
yuv=<n>
Select the type of YUV to RGB conversion. If set to
anything except 0 OSD will be disabled and brightness,
contrast and gamma setting is only available via the
global X server settings. Apart from this the values
have the same meaning as for -vo gl.
matrixview
OpenGL-based renderer creating a Matrix-like running-text
effect.
cols=<n>
Number of text columns to display. Very low values (<
16) will probably fail due to scaler limitations.
Values not divisible by 16 may cause issues as well.
rows=<n>
Number of text rows to display. Very low values (< 16)
will probably fail due to scaler limitations. Values
not divisible by 16 may cause issues as well.
null
Produces no video output. Useful for benchmarking.
aa
ASCII art video output driver that works on a text console. You
can get a list and an explanation of available suboptions by
executing 'mplayer -vo aa:help'.
NOTE: The driver does not handle -aspect correctly.
HINT: You probably have to specify -monitorpixelaspect. Try
'mplayer -vo aa -monitorpixelaspect 0.5'.
caca
Color ASCII art video output driver that works on a text
console.
bl
Video playback using the Blinkenlights UDP protocol. This
driver is highly hardware specific.
<subdevice>
Explicitly choose the Blinkenlights subdevice driver to
use. It is something like arcade:host=localhost:2323 or
hdl:file=name1,file=name2. You must specify a
subdevice.
ggi
GGI graphics system video output driver
<driver>
Explicitly choose the GGI driver to use. Replace any
',' that would appear in the driver string by a '.'.
directfb
Play video using the DirectFB library.
(no)input
Use the DirectFB instead of the MPlayer keyboard code
(default: enabled).
buffermode=single|double|triple
Double and triple buffering give best results if you
want to avoid tearing issues. Triple buffering is more
efficient than double buffering as it does not block
MPlayer while waiting for the vertical retrace. Single
buffering should be avoided (default: single).
fieldparity=top|bottom
Control the output order for interlaced frames (default:
disabled). Valid values are top = top fields first,
bottom = bottom fields first. This option does not have
any effect on progressive film material like most MPEG
movies are. You need to enable this option if you have
tearing issues or unsmooth motions watching interlaced
film material.
layer=N
Will force layer with ID N for playback (default: -1 -
auto).
dfbopts=<list>
Specify a parameter list for DirectFB.
dfbmga
Matrox G400/G450/G550 specific video output driver that uses the
DirectFB library to make use of special hardware features.
Enables CRTC2 (second head), displaying video independently of
the first head.
(no)input
same as directfb (default: disabled)
buffermode=single|double|triple
same as directfb (default: triple)
fieldparity=top|bottom
same as directfb
(no)bes
Enable the use of the Matrox BES (backend scaler)
(default: disabled). Gives very good results concerning
speed and output quality as interpolated picture
processing is done in hardware. Works only on the
primary head.
(no)spic
Make use of the Matrox sub picture layer to display the
OSD (default: enabled).
(no)crtc2
Turn on TV-out on the second head (default: enabled).
The output quality is amazing as it is a full interlaced
picture with proper sync to every odd/even field.
tvnorm=pal|ntsc|auto
Will set the TV norm of the Matrox card without the need
for modifying /etc/directfbrc (default: disabled).
Valid norms are pal = PAL, ntsc = NTSC. Special norm is
auto (auto-adjust using PAL/NTSC) because it decides
which norm to use by looking at the framerate of the
movie.
mga (Linux only)
Matrox specific video output driver that makes use of the YUV
back end scaler on Gxxx cards through a kernel module. If you
have a Matrox card, this is the fastest option.
<device>
Explicitly choose the Matrox device name to use
(default: /dev/mga_vid).
xmga (Linux, X11 only)
The mga video output driver, running in an X11 window.
<device>
Explicitly choose the Matrox device name to use
(default: /dev/mga_vid).
s3fb (Linux only) (also see -dr)
S3 Virge specific video output driver. This driver supports the
card's YUV conversion and scaling, double buffering and direct
rendering features. Use -vf format=yuy2 to get hardware-
accelerated YUY2 rendering, which is much faster than YV12 on
this card.
<device>
Explicitly choose the fbdev device name to use (default:
/dev/fb0).
wii (Linux only)
Nintendo Wii/GameCube specific video output driver.
3dfx (Linux only)
3dfx-specific video output driver that directly uses the
hardware on top of X11. Only 16 bpp are supported.
tdfxfb (Linux only)
This driver employs the tdfxfb framebuffer driver to play movies
with YUV acceleration on 3dfx cards.
<device>
Explicitly choose the fbdev device name to use (default:
/dev/fb0).
tdfx_vid (Linux only)
3dfx-specific video output driver that works in combination with
the tdfx_vid kernel module.
<device>
Explicitly choose the device name to use (default: /dev/
tdfx_vid).
dxr3 (DXR3 only)
Sigma Designs em8300 MPEG decoder chip (Creative DXR3, Sigma
Designs Hollywood Plus) specific video output driver. Also see
the lavc video filter.
overlay
Activates the overlay instead of TV-out.
prebuf
Turns on prebuffering.
sync
Will turn on the new sync-engine.
norm=<norm>
Specifies the TV norm.
0: Does not change current norm (default).
1: Auto-adjust using PAL/NTSC.
2: Auto-adjust using PAL/PAL-60.
3: PAL
4: PAL-60
5: NTSC
<0-3>
Specifies the device number to use if you have more than
one em8300 card.
ivtv (IVTV only)
Conexant CX23415 (iCompression iTVC15) or Conexant CX23416
(iCompression iTVC16) MPEG decoder chip (Hauppauge WinTV
PVR-150/250/350/500) specific video output driver for TV-out.
Also see the lavc video filter.
<device>
Explicitly choose the MPEG decoder device name to use
(default: /dev/video16).
<output>
Explicitly choose the TV-out output to be used for the
video signal.
v4l2 (requires Linux 2.6.22+ kernel)
Video output driver for V4L2 compliant cards with built-in
hardware MPEG decoder. Also see the lavc video filter.
<device>
Explicitly choose the MPEG decoder device name to use
(default: /dev/video16).
<output>
Explicitly choose the TV-out output to be used for the
video signal.
mpegpes (DVB only)
Video output driver for DVB cards that writes the output to an
MPEG-PES file if no DVB card is installed.
card=<1-4>
Specifies the device number to use if you have more than
one DVB output card (V3 API only, such as 1.x.y series
drivers). If not specified MPlayer will search the
first usable card.
<filename>
output filename (default: ./grab.mpg)
md5sum
Calculate MD5 sums of each frame and write them to a file.
Supports RGB24 and YV12 colorspaces. Useful for debugging.
outfile=<value>
Specify the output filename (default: ./md5sums).
yuv4mpeg
Transforms the video stream into a sequence of uncompressed YUV
4:2:0 images and stores it in a file (default: ./stream.yuv).
The format is the same as the one employed by mjpegtools, so
this is useful if you want to process the video with the
mjpegtools suite. It supports the YV12 format. If your source
file has a different format and is interlaced, make sure to use
-vf scale=::1 to ensure the conversion uses interlaced mode.
You can combine it with the -fixed-vo option to concatenate
files with the same dimensions and fps value.
interlaced
Write the output as interlaced frames, top field first.
interlaced_bf
Write the output as interlaced frames, bottom field
first.
file=<filename>
Write the output to <filename> instead of the default
stream.yuv.
NOTE: If you do not specify any option the output is progressive
(i.e. not interlaced).
gif89a
Output each frame into a single animated GIF file in the current
directory. It supports only RGB format with 24 bpp and the
output is converted to 256 colors.
<fps>
Float value to specify framerate (default: 5.0).
<output>
Specify the output filename (default: ./out.gif).
NOTE: You must specify the framerate before the filename or the
framerate will be part of the filename.
EXAMPLE:
mplayer video.nut -vo gif89a:fps=15:output=test.gif
jpeg
Output each frame into a JPEG file in the current directory.
Each file takes the frame number padded with leading zeros as
name.
[no]progressive
Specify standard or progressive JPEG (default:
noprogressive).
[no]baseline
Specify use of baseline or not (default: baseline).
optimize=<0-100>
optimization factor (default: 100)
smooth=<0-100>
smooth factor (default: 0)
quality=<0-100>
quality factor (default: 75)
outdir=<dirname>
Specify the directory to save the JPEG files to
(default: ./).
subdirs=<prefix>
Create numbered subdirectories with the specified prefix
to save the files in instead of the current directory.
maxfiles=<value> (subdirs only)
Maximum number of files to be saved per subdirectory.
Must be equal to or larger than 1 (default: 1000).
pnm
Output each frame into a PNM file in the current directory.
Each file takes the frame number padded with leading zeros as
name. It supports PPM, PGM and PGMYUV files in both raw and
ASCII mode. Also see pnm(5), ppm(5) and pgm(5).
ppm
Write PPM files (default).
pgm
Write PGM files.
pgmyuv
Write PGMYUV files. PGMYUV is like PGM, but it also
contains the U and V plane, appended at the bottom of
the picture.
raw
Write PNM files in raw mode (default).
ascii
Write PNM files in ASCII mode.
outdir=<dirname>
Specify the directory to save the PNM files to (default:
./).
subdirs=<prefix>
Create numbered subdirectories with the specified prefix
to save the files in instead of the current directory.
maxfiles=<value> (subdirs only)
Maximum number of files to be saved per subdirectory.
Must be equal to or larger than 1 (default: 1000).
png
Output each frame into a PNG file in the current directory.
Each file takes the frame number padded with leading zeros as
name. 24bpp RGB and BGR formats are supported.
z=<0-9>
Specifies the compression level. 0 is no compression, 9
is maximum compression.
alpha
Create PNG files with an alpha channel. Note that
MPlayer in general does not support alpha, so this will
only be useful in some rare cases.
tga
Output each frame into a Targa file in the current directory.
Each file takes the frame number padded with leading zeros as
name. The purpose of this video output driver is to have a
simple lossless image writer to use without any external
library. It supports the BGR[A] color format, with 15, 24 and
32 bpp. You can force a particular format with the format video
filter.
EXAMPLE:
mplayer video.nut -vf format=bgr15 -vo tga
DECODING/FILTERING OPTIONS
-ac <[-|+]codec1,[-|+]codec2,...[,]>
Specify a priority list of audio codecs to be used, according to
their codec name in codecs.conf. Use a '-' before the codec
name to omit it. Use a '+' before the codec name to force it,
this will likely crash! If the list has a trailing ',' MPlayer
will fall back on codecs not contained in the list.
NOTE: See -ac help for a full list of available codecs.
EXAMPLE:
-ac mp3acm
Force the l3codeca.acm MP3 codec.
-ac mad,
Try libmad first, then fall back on others.
-ac hwac3,a52,
Try hardware AC-3 passthrough, software AC-3, then
others.
-ac hwdts,
Try hardware DTS passthrough, then fall back on others.
-ac -ffmp3,
Skip FFmpeg's MP3 decoder.
-af-adv <force=(0-7):list=(filters)> (also see -af)
Specify advanced audio filter options:
force=<0-7>
Forces the insertion of audio filters to one of the
following:
0: Use completely automatic filter insertion
(currently identical to 1).
1: Optimize for accuracy (default).
2: Optimize for speed. Warning: Some features in the
audio filters may silently fail, and the sound
quality may drop.
3: Use no automatic insertion of filters and no
optimization. Warning: It may be possible to crash
MPlayer using this setting.
4: Use automatic insertion of filters according to 0
above, but use floating point processing when
possible.
5: Use automatic insertion of filters according to 1
above, but use floating point processing when
possible.
6: Use automatic insertion of filters according to 2
above, but use floating point processing when
possible.

3 above, and use floating point processing when
possible.
list=<filters>
Same as -af.
-afm <driver1,driver2,...>
Specify a priority list of audio codec families to be used,
according to their codec name in codecs.conf. Falls back on the
default codecs if none of the given codec families work.
NOTE: See -afm help for a full list of available codec families.
EXAMPLE:
-afm ffmpeg
Try FFmpeg's libavcodec codecs first.
-afm acm,dshow
Try Win32 codecs first.
-aspect <ratio> (also see -zoom)
Override movie aspect ratio, in case aspect information is
incorrect or missing in the file being played.

appropriate information, it falls back to 0 (top field
first).
0 top field first
1 bottom field first
-flip
Flip image upside-down.
-lavdopts <option1:option2:...> (DEBUG CODE)

debug=<value>
Display debugging information.
0: disabled
1: picture info
2: rate control
4: bitstream
8: macroblock (MB) type
16: per-block quantization parameter (QP)
32: motion vector
0x0040: motion vector visualization (use -noslices)
0x0080: macroblock (MB) skip
0x0100: startcode
0x0200: PTS
0x0400: error resilience
0x0800: memory management control operations (H.264)
0x1000: bugs

3: aggressive (More checks, but might cause problems
even for valid bitstreams.)
4: very aggressive
fast (MPEG-2, MPEG-4, and H.264 only)
Enable optimizations which do not comply to the
specification and might potentially cause problems, like
simpler dequantization, simpler motion compensation,
assuming use of the default quantization matrix,
assuming YUV 4:2:0 and skipping a few checks to detect
damaged bitstreams.
gray
grayscale only decoding (a bit faster than with color)
idct=<0-99> (see -lavcopts)
For best decoding quality use the same IDCT algorithm
for decoding and encoding. This may come at a price in
accuracy, though.
lowres=<number>[,<w>]
Decode at lower resolutions. Low resolution decoding is
not supported by all codecs, and it will often result in
ugly artifacts. This is not a bug, but a side effect of
not decoding at full resolution.
0: disabled
1: 1/2 resolution
2: 1/4 resolution
3: 1/8 resolution
If <w> is specified lowres decoding will be used only if
the width of the video is major than or equal to <w>.
o=<key>=<value>[,<key>=<value>[,...]] Pass AVOptions to
libavcodec decoder. Note, a patch to make the o= unneeded
and pass all unknown options through the AVOption system is
welcome. A full list of AVOptions can be found in the FFmpeg
manual.
EXAMPLE:
o=debug=pict
sb=<number> (MPEG-2 only)
Skip the given number of macroblock rows at the bottom.
st=<number> (MPEG-2 only)
Skip the given number of macroblock rows at the top.
skiploopfilter=<skipvalue> (H.264 only)
Skips the loop filter (AKA deblocking) during H.264
decoding. Since the filtered frame is supposed to be
used as reference for decoding dependent frames this has
a worse effect on quality than not doing deblocking on
e.g. MPEG-2 video. But at least for high bitrate HDTV
this provides a big speedup with no visible quality
loss.
<skipvalue> can be either one of the following:
none: Never skip.
default: Skip useless processing steps (e.g. 0 size
packets in AVI).
nonref: Skip frames that are not referenced (i.e. not
used for decoding other frames, the error cannot
"build up").
bidir: Skip B-Frames.
nonkey: Skip all frames except keyframes.
all: Skip all frames.
skipidct=<skipvalue> (MPEG-1/2 only)
Skips the IDCT step. This degrades quality a lot of in
almost all cases (see skiploopfilter for available skip
values).
skipframe=<skipvalue>
Skips decoding of frames completely. Big speedup, but
jerky motion and sometimes bad artifacts (see
skiploopfilter for available skip values).
threads=<0-16>
Number of threads to use for decoding. Whether
threading is actually supported depends on codec. 0
means autodetect number of cores on the machine and use
that, up to the maximum of 16. (default: 0)
vismv=<value>
Visualize motion vectors.
0: disabled
1: Visualize forward predicted MVs of P-frames.
2: Visualize forward predicted MVs of B-frames.
4: Visualize backward predicted MVs of B-frames.
vstats
Prints some statistics and stores them in
./vstats_*.log.
-noslices
Disable drawing video by 16-pixel height slices/bands, instead
draws the whole frame in a single run. May be faster or slower,
depending on video card and available cache. It has effect only
with libmpeg2 and libavcodec codecs.
-nosound
Do not play sound. Useful for benchmarking.
-novideo
Do not play video. With some demuxers this may not work. In
those cases you can try -vc null -vo null instead; but "-vc
null" is always unreliable.
-pp <quality> (also see -vf pp)
Set the DLL postprocess level. This option is no longer usable
with -vf pp. It only works with Win32 DirectShow DLLs with
internal postprocessing routines. The valid range of -pp values
varies by codec, it is mostly 0-6, where 0=disable, 6=slowest/
best.
-pphelp (also see -vf pp)
Show a summary about the available postprocess filters and their
usage.
-ssf <mode>
Specifies software scaler parameters.
EXAMPLE:
-vf scale -ssf lgb=3.0
lgb=<0-100>
gaussian blur filter (luma)
cgb=<0-100>
gaussian blur filter (chroma)
ls=<-100-100>
sharpen filter (luma)
cs=<-100-100>
sharpen filter (chroma)
chs=<h>
chroma horizontal shifting
cvs=<v>
chroma vertical shifting
-stereo <mode>
Select type of MP2/MP3 stereo output.
0 stereo
1 left channel
2 right channel
-sws <software scaler type> (also see -vf scale and -zoom)
Specify the software scaler algorithm to be used with the -zoom
option. This affects video output drivers which lack hardware
acceleration, e.g. x11.
Available types are:
0 fast bilinear
1 bilinear
2 bicubic (good quality) (default)
3 experimental
4 nearest neighbor (bad quality)
5 area
6 luma bicubic / chroma bilinear
7 gauss
8 sincR
9 lanczos
10 natural bicubic spline
NOTE: Some -sws options are tunable. The description of the
scale video filter has further information.
-vc <[-|+]codec1,[-|+]codec2,...[,]>
Specify a priority list of video codecs to be used, according to
their codec name in codecs.conf. Use a '-' before the codec
name to omit it. Use a '+' before the codec name to force it,
this will likely crash! If the list has a trailing ',' MPlayer
will fall back on codecs not contained in the list.
NOTE: See -vc help for a full list of available codecs.
EXAMPLE:
-vc divx
Force Win32/VfW DivX codec, no fallback.
-vc -divxds,-divx,
Skip Win32 DivX codecs.
-vc ffmpeg12,mpeg12,
Try libavcodec's MPEG-1/2 codec, then libmpeg2, then
others.
-vfm <driver1,driver2,...>
Specify a priority list of video codec families to be used,
according to their names in codecs.conf. Falls back on the
default codecs if none of the given codec families work.
NOTE: See -vfm help for a full list of available codec families.
EXAMPLE:
-vfm ffmpeg,dshow,vfw
Try the libavcodec, then Directshow, then VfW codecs and
fall back on others, if they do not work.
-vfm xanim
Try XAnim codecs first.
-x <x> (also see -zoom)
Scale image to width <x> (if software/hardware scaling is
available). Disables aspect calculations.
-xvidopts <option1:option2:...>
Specify additional parameters when decoding with Xvid.
NOTE: Since libavcodec is faster than Xvid you might want to use
the libavcodec postprocessing filter (-vf pp) and decoder (-vfm
ffmpeg) instead.
Xvid's internal postprocessing filters:
deblock-chroma (also see -vf pp)
chroma deblock filter
deblock-luma (also see -vf pp)
luma deblock filter
dering-luma (also see -vf pp)
luma deringing filter
dering-chroma (also see -vf pp)
chroma deringing filter
filmeffect (also see -vf noise)
Adds artificial film grain to the video. May increase
perceived quality, while lowering true quality.
rendering methods:
dr2
Activate direct rendering method 2.
nodr2
Deactivate direct rendering method 2.
-xy <value> (also see -zoom)
value<=8
Scale image by factor <value>.
value>8
Set width to value and calculate height to keep correct
aspect ratio.
-y <y> (also see -zoom)
Scale image to height <y> (if software/hardware scaling is
available). Disables aspect calculations.
-zoom
Allow software scaling, where available. This will allow
scaling with output drivers (like x11, fbdev) that do not
support hardware scaling where MPlayer disables scaling by
default for performance reasons.
AUDIO FILTERS
Audio filters allow you to modify the audio stream and its properties.
The syntax is:
-af <filter1[=parameter1:parameter2:...],filter2,...>
Setup a chain of audio filters.
NOTE: To get a full list of available audio filters, see -af help.
Audio filters are managed in lists. There are a few commands to manage
the filter list.
-af-add <filter1[,filter2,...]>
Appends the filters given as arguments to the filter list.
-af-pre <filter1[,filter2,...]>
Prepends the filters given as arguments to the filter list.
-af-del <index1[,index2,...]>
Deletes the filters at the given indexes. Index numbers start
at 0, negative numbers address the end of the list (-1 is the
last).
-af-clr
Completely empties the filter list.
Available filters are:
resample[=srate[:sloppy[:type]]]
Changes the sample rate of the audio stream. Can be used if you
have a fixed frequency sound card or if you are stuck with an
old sound card that is only capable of max 44.1kHz. This filter
is automatically enabled if necessary. It only supports 16-bit
integer and float in native-endian format as input.
<srate>
output sample frequency in Hz. The valid range for this
parameter is 8000 to 192000. If the input and output
sample frequency are the same or if this parameter is
omitted the filter is automatically unloaded. A high
sample frequency normally improves the audio quality,
especially when used in combination with other filters.
<sloppy>
Allow (1) or disallow (0) the output frequency to differ
slightly from the frequency given by <srate> (default:
1). Can be used if the startup of the playback is
extremely slow.
<type>
Select which resampling method to use.
0: linear interpolation (fast, poor quality
especially when upsampling)
1: polyphase filterbank and integer processing
2: polyphase filterbank and floating point processing
(slow, best quality)
EXAMPLE:
mplayer -af resample=44100:0:0
would set the output frequency of the resample filter to
44100Hz using exact output frequency scaling and linear
interpolation.
lavcresample[=srate[:length[:linear[:count[:cutoff]]]]]
Changes the sample rate of the audio stream to an integer
<srate> in Hz. It only supports the 16-bit native-endian
format.
<srate>
the output sample rate
<length>
length of the filter with respect to the lower sampling
rate (default: 16)
<linear>
if 1 then filters will be linearly interpolated between
polyphase entries
<count>
log2 of the number of polyphase entries (..., 10->1024,
11->2048, 12->4096, ...) (default: 10->1024)
<cutoff>
cutoff frequency (0.0-1.0), default set depending upon
filter length
lavcac3enc[=tospdif[:bitrate[:minchn]]]
Encode multi-channel audio to AC-3 at runtime using libavcodec.
Supports 16-bit native-endian input format, maximum 6 channels.
The output is big-endian when outputting a raw AC-3 stream,
native-endian when outputting to S/PDIF. The output sample rate
of this filter is same with the input sample rate. When input
sample rate is 48kHz, 44.1kHz, or 32kHz, this filter directly
use it. Otherwise a resampling filter is auto-inserted before
this filter to make the input and output sample rate be 48kHz.
You need to specify '-channels N' to make the decoder decode
audio into N-channel, then the filter can encode the N-channel
input to AC-3.
<tospdif>
Output raw AC-3 stream if zero or not set, output to
S/PDIF for passthrough when <tospdif> is set non-zero.
<bitrate>
The bitrate to encode the AC-3 stream. Set it to either
384 or 384000 to get 384kbits. Valid values: 32, 40,
48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256,
320, 384, 448, 512, 576, 640 Default
bitrate is based on the input channel number: 1ch: 96,
2ch: 192, 3ch: 224, 4ch: 384, 5ch: 448, 6ch: 448
<minchn>
If the input channel number is less than <minchn>, the
filter will detach itself (default: 5).
sweep[=speed]
Produces a sine sweep.
<0.0-1.0>
Sine function delta, use very low values to hear the
sweep.
sinesuppress[=freq:decay]
Remove a sine at the specified frequency. Useful to get rid of
the 50/60Hz noise on low quality audio equipment. It probably
only works on mono input.
<freq>
The frequency of the sine which should be removed (in
Hz) (default: 50)
<decay>
Controls the adaptivity (a larger value will make the
filter adapt to amplitude and phase changes quicker, a
smaller value will make the adaptation slower) (default:
0.0001). Reasonable values are around 0.001.
bs2b[=option1:option2:...]
Bauer stereophonic to binaural transformation using libbs2b.
Improves the headphone listening experience by making the sound
similar to that from loudspeakers, allowing each ear to hear
both channels and taking into account the distance difference
and the head shadowing effect. It is applicable only to 2
channel audio.
fcut=<300-1000>
Set cut frequency in Hz.
feed=<10-150>
Set feed level for low frequencies in 0.1*dB.
profile=<value>
Several profiles are available for convenience:
default
will be used if nothing else was specified
(fcut=700, feed=45)
cmoy
Chu Moy circuit implementation (fcut=700,
feed=60)
jmeier
Jan Meier circuit implementation (fcut=650,
feed=95)
If fcut or feed options are specified together with a profile,
they will be applied on top of the selected profile.
hrtf[=flag]
Head-related transfer function: Converts multichannel audio to 2
channel output for headphones, preserving the spatiality of the
sound.
Flag Meaning
m matrix decoding of the rear channel
s 2-channel matrix decoding
0 no matrix decoding (default)
equalizer=[g1:g2:g3:...:g10]
10 octave band graphic equalizer, implemented using 10 IIR band
pass filters. This means that it works regardless of what type
of audio is being played back. The center frequencies for the
10 bands are:
No. frequency
0 31.25 Hz
1 62.50 Hz
2 125.00 Hz
3 250.00 Hz
4 500.00 Hz
5 1.00 kHz
6 2.00 kHz
7 4.00 kHz
8 8.00 kHz
9 16.00 kHz
If the sample rate of the sound being played is lower than the
center frequency for a frequency band, then that band will be
disabled. A known bug with this filter is that the
characteristics for the uppermost band are not completely
symmetric if the sample rate is close to the center frequency of
that band. This problem can be worked around by upsampling the
sound using the resample filter before it reaches this filter.
<g1>:<g2>:<g3>:...:<g10>
floating point numbers representing the gain in dB for
each frequency band (-12-12)
EXAMPLE:
mplayer -af equalizer=11:11:10:5:0:-12:0:5:12:12 media.avi
Would amplify the sound in the upper and lower frequency
region while canceling it almost completely around 1kHz.
channels=nch[:nr:from1:to1:from2:to2:from3:to3:...]
Can be used for adding, removing, routing and copying audio
channels. If only <nch> is given the default routing is used,
it works as follows: If the number of output channels is bigger
than the number of input channels empty channels are inserted
(except mixing from mono to stereo, then the mono channel is
repeated in both of the output channels). If the number of
output channels is smaller than the number of input channels the
exceeding channels are truncated.
<nch>
number of output channels (1-8)
<nr>
number of routes (1-8)
<from1:to1:from2:to2:from3:to3:...>
Pairs of numbers between 0 and 7 that define where to
route each channel.
EXAMPLE:
mplayer -af channels=4:4:0:1:1:0:2:2:3:3 media.avi
Would change the number of channels to 4 and set up 4
routes that swap channel 0 and channel 1 and leave
channel 2 and 3 intact. Observe that if media
containing two channels was played back, channels 2 and
3 would contain silence but 0 and 1 would still be
swapped.
mplayer -af channels=6:4:0:0:0:1:0:2:0:3 media.avi
Would change the number of channels to 6 and set up 4
routes that copy channel 0 to channels 0 to 3. Channel
4 and 5 will contain silence.
format[=format] (also see -format)
Convert between different sample formats. Automatically enabled
when needed by the sound card or another filter.
<format>
Sets the desired format. The general form is 'sbe',
where 's' denotes the sign (either 's' for signed or 'u'
for unsigned), 'b' denotes the number of bits per sample
(16, 24 or 32) and 'e' denotes the endianness ('le'
means little-endian, 'be' big-endian and 'ne' the
endianness of the computer MPlayer is running on).
Valid values (amongst others) are: 's16le', 'u32be' and
'u24ne'. Exceptions to this rule that are also valid
format specifiers: u8, s8, floatle, floatbe, floatne,
mulaw, alaw, mpeg2, ac3 and imaadpcm.
volume[=v[:sc]]
Implements software volume control. Use this filter with
caution since it can reduce the signal to noise ratio of the
sound. In most cases it is best to set the level for the PCM
sound to max, leave this filter out and control the output level
to your speakers with the master volume control of the mixer.
In case your sound card has a digital PCM mixer instead of an
analog one, and you hear distortion, use the MASTER mixer
instead. If there is an external amplifier connected to the
computer (this is almost always the case), the noise level can
be minimized by adjusting the master level and the volume knob
on the amplifier until the hissing noise in the background is
gone.
This filter has a second feature: It measures the overall
maximum sound level and prints out that level when MPlayer
exits. This feature currently only works with floating-point
data, use e.g. -af-adv force=5, or use -af stats.
NOTE: This filter is not reentrant and can therefore only be
enabled once for every audio stream.
<v>
Sets the desired gain in dB for all channels in the
stream from -200dB to +60dB, where -200dB mutes the
sound completely and +60dB equals a gain of 1000
(default: 0).
<sc>
Turns soft clipping on (1) or off (0). Soft-clipping
can make the sound more smooth if very high volume
levels are used. Enable this option if the dynamic
range of the loudspeakers is very low.
WARNING: This feature creates distortion and should be
considered a last resort.
EXAMPLE:
mplayer -af volume=10.1:0 media.avi
Would amplify the sound by 10.1dB and hard-clip if the
sound level is too high.
pan=n[:L00:L01:L02:...L10:L11:L12:...Ln0:Ln1:Ln2:...]
Mixes channels arbitrarily. Basically a combination of the
volume and the channels filter that can be used to down-mix many
channels to only a few, e.g. stereo to mono or vary the "width"
of the center speaker in a surround sound system. This filter
is hard to use, and will require some tinkering before the
desired result is obtained. The number of options for this
filter depends on the number of output channels. An example how
to downmix a six-channel file to two channels with this filter
can be found in the examples section near the end.
<n>
number of output channels (1-8)
<Lij>
How much of input channel i is mixed into output channel
j (0-1). So in principle you first have n numbers
saying what to do with the first input channel, then n
numbers that act on the second input channel etc. If
you do not specify any numbers for some input channels,
0 is assumed.
EXAMPLE:
mplayer -af pan=1:0.5:0.5 media.avi
Would down-mix from stereo to mono.
mplayer -af pan=3:1:0:0.5:0:1:0.5 media.avi
Would give 3 channel output leaving channels 0 and 1
intact, and mix channels 0 and 1 into output channel 2
(which could be sent to a subwoofer for example).
sub[=fc:ch]
Adds a subwoofer channel to the audio stream. The audio data
used for creating the subwoofer channel is an average of the
sound in channel 0 and channel 1. The resulting sound is then
low-pass filtered by a 4th order Butterworth filter with a
default cutoff frequency of 60Hz and added to a separate channel
in the audio stream.
Warning: Disable this filter when you are playing DVDs with
Dolby Digital 5.1 sound, otherwise this filter will disrupt the
sound to the subwoofer.
<fc>
cutoff frequency in Hz for the low-pass filter (20Hz to
300Hz) (default: 60Hz) For the best result try setting
the cutoff frequency as low as possible. This will
improve the stereo or surround sound experience.
<ch>
Determines the channel number in which to insert the
sub-channel audio. Channel number can be between 0 and
7 (default: 5). Observe that the number of channels
will automatically be increased to <ch> if necessary.
EXAMPLE:
mplayer -af sub=100:4 -channels 5 media.avi
Would add a sub-woofer channel with a cutoff frequency
of 100Hz to output channel 4.
center
Creates a center channel from the front channels. May currently
be low quality as it does not implement a high-pass filter for
proper extraction yet, but averages and halves the channels
instead.
<ch>
Determines the channel number in which to insert the
center channel. Channel number can be between 0 and 7
(default: 5). Observe that the number of channels will
automatically be increased to <ch> if necessary.
surround[=delay]
Decoder for matrix encoded surround sound like Dolby Surround.
Many files with 2 channel audio actually contain matrixed
surround sound. Requires a sound card supporting at least 4
channels.
<delay>
delay time in ms for the rear speakers (0 to 1000)
(default: 20) This delay should be set as follows: If d1
is the distance from the listening position to the front
speakers and d2 is the distance from the listening
position to the rear speakers, then the delay should be
set to 15ms if d1 <= d2 and to 15 + 5*(d1-d2) if d1 >
d2.
EXAMPLE:
mplayer -af surround=15 -channels 4 media.avi
Would add surround sound decoding with 15ms delay for
the sound to the rear speakers.
delay[=ch1:ch2:...]
Delays the sound to the loudspeakers such that the sound from
the different channels arrives at the listening position
simultaneously. It is only useful if you have more than 2
loudspeakers.
ch1,ch2,...
The delay in ms that should be imposed on each channel
(floating point number between 0 and 1000).
To calculate the required delay for the different channels do as
follows:
1. Measure the distance to the loudspeakers in meters in
relation to your listening position, giving you the distances
s1 to s5 (for a 5.1 system). There is no point in
compensating for the subwoofer (you will not hear the
difference anyway).
2. Subtract the distances s1 to s5 from the maximum distance,
i.e. s[i] = max(s) - s[i]; i = 1...5.
3. Calculate the required delays in ms as d[i] = 1000*s[i]/342;
i = 1...5.
EXAMPLE:
mplayer -af delay=10.5:10.5:0:0:7:0 media.avi
Would delay front left and right by 10.5ms, the two rear
channels and the sub by 0ms and the center channel by
7ms.
export[=mmapped_file[:nsamples]]
Exports the incoming signal to other processes using memory
mapping (mmap()). Memory mapped areas contain a header:
int nch /*number of channels*/
int size /*buffer size*/
unsigned long long counter /*Used to keep sync, updated every
time new data is exported.*/
The rest is payload (non-interleaved) 16 bit data.
<mmapped_file>
file to map data to (default: ~/.mplayer/mplayer-
af_export)
<nsamples>
number of samples per channel (default: 512)
EXAMPLE:
mplayer -af export=/tmp/mplayer-af_export:1024 media.avi
Would export 1024 samples per channel to '/tmp/mplayer-
af_export'.
extrastereo[=mul]
(Linearly) increases the difference between left and right
channels which adds some sort of "live" effect to playback.
<mul>
Sets the difference coefficient (default: 2.5). 0.0
means mono sound (average of both channels), with 1.0
sound will be unchanged, with -1.0 left and right
channels will be swapped.
volnorm[=method:target]
Maximizes the volume without distorting the sound.
<method>
Sets the used method.
1: Use a single sample to smooth the variations via
the standard weighted mean over past samples
(default).
2: Use several samples to smooth the variations via
the standard weighted mean over past samples.
<target>
Sets the target amplitude as a fraction of the maximum
for the sample type (default: 0.25).
ladspa=file:label[:controls...]
Load a LADSPA (Linux Audio Developer's Simple Plugin API)
plugin. This filter is reentrant, so multiple LADSPA plugins
can be used at once.
<file>
Specifies the LADSPA plugin library file. If
LADSPA_PATH is set, it searches for the specified file.
If it is not set, you must supply a fully specified
pathname.
<label>
Specifies the filter within the library. Some libraries
contain only one filter, but others contain many of
them. Entering 'help' here, will list all available
filters within the specified library, which eliminates
the use of 'listplugins' from the LADSPA SDK.
<controls>
Controls are zero or more floating point values that
determine the behavior of the loaded plugin (for example
delay, threshold or gain). In verbose mode (add -v to
the MPlayer command line), all available controls and
their valid ranges are printed. This eliminates the use
of 'analyseplugin' from the LADSPA SDK.
comp
Compressor/expander filter usable for microphone input.
Prevents artifacts on very loud sound and raises the volume on
very low sound. This filter is untested, maybe even unusable.
gate
Noise gate filter similar to the comp audio filter. This filter
is untested, maybe even unusable.
karaoke
Simple voice removal filter exploiting the fact that voice is
usually recorded with mono gear and later 'center' mixed onto
the final audio stream. Beware that this filter will turn your
signal into mono. Works well for 2 channel tracks; do not
bother trying it on anything but 2 channel stereo.
scaletempo[=option1:option2:...]
Scales audio tempo without altering pitch, optionally synced to
playback speed (default).
This works by playing 'stride' ms of audio at normal speed then
consuming 'stride*scale' ms of input audio. It pieces the
strides together by blending 'overlap'% of stride with audio
following the previous stride. It optionally performs a short
statistical analysis on the next 'search' ms of audio to
determine the best overlap position.
scale=<amount>
Nominal amount to scale tempo. Scales this amount in
addition to speed. (default: 1.0)
stride=<amount>
Length in milliseconds to output each stride. Too high
of value will cause noticable skips at high scale
amounts and an echo at low scale amounts. Very low
values will alter pitch. Increasing improves
performance. (default: 60)
overlap=<percent>
Percentage of stride to overlap. Decreasing improves
performance. (default: .20)
search=<amount>
Length in milliseconds to search for best overlap
position. Decreasing improves performance greatly. On
slow systems, you will probably want to set this very
low. (default: 14)
speed=<tempo|pitch|both|none>
Set response to speed change.
tempo
Scale tempo in sync with speed (default).
pitch
Reverses effect of filter. Scales pitch without
altering tempo. Add '[ speed_mult
0.9438743126816935' and '] speed_mult
1.059463094352953' to your input.conf to step by
musical semi-tones. WARNING: Loses sync with
video.
both Scale both tempo and pitch.
none Ignore speed changes.
EXAMPLE:
mplayer -af scaletempo -speed 1.2 media.ogg
Would playback media at 1.2x normal speed, with audio at
normal pitch. Changing playback speed, would change
audio tempo to match.
mplayer -af scaletempo=scale=1.2:speed=none -speed 1.2
media.ogg
Would playback media at 1.2x normal speed, with audio at
normal pitch, but changing playback speed has no effect
on audio tempo.
mplayer -af scaletempo=stride=30:overlap=.50:search=10
media.ogg
Would tweak the quality and performace parameters.
mplayer -af format=floatne,scaletempo media.ogg
Would make scaletempo use float code. Maybe faster on
some platforms.
mplayer -af scaletempo=scale=1.2:speed=pitch audio.ogg
Would playback audio file at 1.2x normal speed, with
audio at normal pitch. Changing playback speed, would
change pitch, leaving audio tempo at 1.2x.
stats
Collects and prints statistics about the audio stream,
especially the volume. These statistics are especially intended
to help adjusting the volume while avoiding clipping. The
volumes are printed in dB and compatible with the volume audio
filter.
VIDEO FILTERS
Video filters allow you to modify the video stream and its properties.
The syntax is:
-vf <filter1[=parameter1:parameter2:...],filter2,...>
Setup a chain of video filters.
Many parameters are optional and set to default values if omitted. To
explicitly use a default value set a parameter to '-1'. Parameters w:h
means width x height in pixels, x:y means x;y position counted from the
upper left corner of the bigger image.
NOTE: To get a full list of available video filters, see -vf help.
Video filters are managed in lists. There are a few commands to manage
the filter list.
-vf-add <filter1[,filter2,...]>
Appends the filters given as arguments to the filter list.
-vf-pre <filter1[,filter2,...]>
Prepends the filters given as arguments to the filter list.
-vf-del <index1[,index2,...]>
Deletes the filters at the given indexes. Index numbers start
at 0, negative numbers address the end of the list (-1 is the
last).
-vf-clr
Completely empties the filter list.
With filters that support it, you can access parameters by their name.
-vf <filter>=help
Prints the parameter names and parameter value ranges for a
particular filter.
-vf <filter=named_parameter1=value1[:named_parameter2=value2:...]>
Sets a named parameter to the given value. Use on and off or
yes and no to set flag parameters.
Available filters are:
crop[=w:h:x:y]
Crops the given part of the image and discards the rest. Useful
to remove black bands from widescreen movies.
<w>,<h>
Cropped width and height, defaults to original width and
height.
<x>,<y>
Position of the cropped picture, defaults to center.
cropdetect[=limit:round[:reset]]
Calculates necessary cropping parameters and prints the
recommended parameters to stdout.
<limit>
Threshold, which can be optionally specified from
nothing (0) to everything (255) (default: 24).
<round>
Value which the width/height should be divisible by
(default: 16). The offset is automatically adjusted to
center the video. Use 2 to get only even dimensions
(needed for 4:2:2 video). 16 is best when encoding to
most video codecs.
<reset>
Counter that determines after how many frames cropdetect
will reset the previously detected largest video area
and start over to detect the current optimal crop area
(default: 0). This can be useful when channel logos
distort the video area. 0 indicates never reset and
return the largest area encountered during playback.
rectangle[=w:h:x:y]
Draws a rectangle of the requested width and height at the
specified coordinates over the image and prints current
rectangle parameters to the console. This can be used to find
optimal cropping parameters. If you bind the input.conf
directive 'change_rectangle' to keystrokes, you can move and
resize the rectangle on the fly.
<w>,<h>
width and height (default: -1, maximum possible width
where boundaries are still visible.)
<x>,<y>
top left corner position (default: -1, uppermost
leftmost)
expand[=w:h:x:y:o:a:r]
Expands (not scales) movie resolution to the given value and
places the unscaled original at coordinates x, y. Can be used
for placing subtitles/OSD in the resulting black bands.
<w>,<h>
Expanded width,height (default: original width,height).
Negative values for w and h are treated as offsets to
the original size.
EXAMPLE:
expand=0:-50:0:0
Adds a 50 pixel border to the bottom of the
picture.
<x>,<y>
position of original image on the expanded image
(default: center)
<o>
OSD/subtitle rendering
0: disable (default)
1: enable
<a>
Expands to fit an aspect instead of a resolution
(default: 0).
EXAMPLE:
expand=800:::::4/3
Expands to 800x600, unless the source is
higher resolution, in which case it expands
to fill a 4/3 aspect.
<r>
Rounds up to make both width and height divisible by <r>
(default: 1).
flip (also see -flip)
Flips the image upside down.
mirror
Mirrors the image on the Y axis.
rotate[=<0-7>]
Rotates the image by 90 degrees and optionally flips it. For
values between 4-7 rotation is only done if the movie geometry
is portrait and not landscape.
0 Rotate by 90 degrees clockwise and flip (default).
1 Rotate by 90 degrees clockwise.
2 Rotate by 90 degrees counterclockwise.
3 Rotate by 90 degrees counterclockwise and flip.
scale[=w:h[:interlaced[:chr_drop[:par[:par2[:presize[:noup[:arnd]]]]]]]]
Scales the image with the software scaler (slow) and performs a
YUV<->RGB colorspace conversion (also see -sws).
<w>,<h>
scaled width/height (default: original width/height)
NOTE: If -zoom is used, and underlying filters
(including libvo) are incapable of scaling, it defaults
to d_width/d_height!
0: scaled d_width/d_height
-1: original width/height
-2: Calculate w/h using the other dimension and the
prescaled aspect ratio.
-3: Calculate w/h using the other dimension and the
original aspect ratio.
-(n+8): Like -n above, but rounding the dimension to
the closest multiple of 16.
<interlaced>
Toggle interlaced scaling.
0: off (default)
1: on
<chr_drop>
chroma skipping
0: Use all available input lines for chroma.
1: Use only every 2. input line for chroma.
2: Use only every 4. input line for chroma.
3: Use only every 8. input line for chroma.
<par>[:<par2>] (also see -sws)
Set some scaling parameters depending on the type of
scaler selected with -sws.
-sws 2 (bicubic): B (blurring) and C (ringing)
0.00:0.60 default
0.00:0.75 VirtualDub's "precise bicubic"
0.00:0.50 Catmull-Rom spline
0.33:0.33 Mitchell-Netravali spline
1.00:0.00 cubic B-spline

faster or slower than the default rounding.
0: Disable accurate rounding (default).
1: Enable accurate rounding.
dsize[=aspect|w:h:aspect-method:r]
Changes the intended display size/aspect at an arbitrary point
in the filter chain. Aspect can be given as a fraction (4/3) or
floating point number (1.33). Alternatively, you may specify
the exact display width and height desired. Note that this
filter does not do any scaling itself; it just affects what
later scalers (software or hardware) will do when auto-scaling
to correct aspect.
<w>,<h>
New display width and height. Can also be these special
values:
0: original display width and height
-1: original video width and height (default)
-2: Calculate w/h using the other dimension and the
original display aspect ratio.
-3: Calculate w/h using the other dimension and the
original video aspect ratio.
EXAMPLE:
dsize=800:-2
Specifies a display resolution of 800x600
for a 4/3 aspect video, or 800x450 for a
16/9 aspect video.
<aspect-method>
Modifies width and height according to original aspect
ratios.
-1: Ignore original aspect ratio (default).
0: Keep display aspect ratio by using <w> and <h> as
maximum resolution.
1: Keep display aspect ratio by using <w> and <h> as
minimum resolution.
2: Keep video aspect ratio by using <w> and <h> as
maximum resolution.
3: Keep video aspect ratio by using <w> and <h> as
minimum resolution.
EXAMPLE:
dsize=800:600:0
Specifies a display resolution of at most
800x600, or smaller, in order to keep
aspect.
<r>
Rounds up to make both width and height divisible by <r>
(default: 1).
yvu9
Forces software YVU9 to YV12 colorspace conversion. Deprecated
in favor of the software scaler.
yuvcsp
Clamps YUV color values to the CCIR 601 range without doing real
conversion.
palette
RGB/BGR 8 -> 15/16/24/32bpp colorspace conversion using palette.
format[=fourcc[:outfourcc]]
Restricts the colorspace for the next filter without doing any
conversion. Use together with the scale filter for a real
conversion.
NOTE: For a list of available formats see format=fmt=help.
<fourcc>
format name like rgb15, bgr24, yv12, etc (default: yuy2)
<outfourcc>
Format name that should be substituted for the output.
If this is not 100% compatible with the <fourcc> value
it will crash.
Valid examples:
format=rgb24:bgr24 format=yuyv:yuy2
Invalid examples (will crash):
format=rgb24:yv12
noformat[=fourcc]
Restricts the colorspace for the next filter without doing any
conversion. Unlike the format filter, this will allow any
colorspace except the one you specify.
NOTE: For a list of available formats see noformat=fmt=help.
<fourcc>
format name like rgb15, bgr24, yv12, etc (default: yv12)
pp[=filter1[:option1[:option2...]]/[-]filter2...] (also see -pphelp)
Enables the specified chain of postprocessing subfilters.
Subfilters must be separated by '/' and can be disabled by
prepending a '-'. Each subfilter and some options have a short
and a long name that can be used interchangeably, i.e. dr/dering
are the same. All subfilters share common options to determine
their scope:
a/autoq
Automatically switch the subfilter off if the CPU is too
slow.
c/chrom
Do chrominance filtering, too (default).
y/nochrom
Do luminance filtering only (no chrominance).

uspp[=quality[:qp]]
Ultra simple & slow postprocessing filter that compresses and
decompresses the image at several (or - in the case of quality
level 8 - all) shifts and averages the results. The way this
differs from the behavior of spp is that uspp actually encodes &
decodes each case with libavcodec Snow, whereas spp uses a
simplified intra only 8x8 DCT similar to MJPEG.

X / Y: the coordinates of the current sample
W / H: width and height of the image
SW / SH: width/height scale depending on the
currently filtered plane, e.g. 1,1 and 0.5,0.5 for
YUV 4:2:0.
p(x,y): returns the value of the pixel at location
x/y of the current plane.

hardware and calculating the y axis scaling in software to keep
aspect. Only useful together with expand and scale.
<aspect>
Control aspect ratio, calculate as
DVB_HEIGHT*ASPECTRATIO (default: 576*4/3=768), set it to
576*(16/9)=1024 for a 16:9 TV.
EXAMPLE:
-vf dvbscale,scale=-1:0,expand=-1:576:-1:-1:1,lavc
FIXME: Explain what this does.
noise[=luma[u][t|a][h][p]:chroma[u][t|a][h][p]]
Adds noise.
<0-100>
luma noise
<0-100>
chroma noise
u uniform noise (gaussian otherwise)
t temporal noise (noise pattern changes between frames)
a averaged temporal noise (smoother, but a lot slower)
h high quality (slightly better looking, slightly slower)
p mix random noise with a (semi)regular pattern
denoise3d[=luma_spatial:chroma_spatial:luma_tmp:chroma_tmp]
This filter aims to reduce image noise producing smooth images
and making still images really still (This should enhance
compressibility.).
<luma_spatial>
spatial luma strength (default: 4)
<chroma_spatial>
spatial chroma strength (default: 3)
<luma_tmp>
luma temporal strength (default: 6)
<chroma_tmp>
chroma temporal strength (default:
luma_tmp*chroma_spatial/luma_spatial)
hqdn3d[=luma_spatial:chroma_spatial:luma_tmp:chroma_tmp]
High precision/quality version of the denoise3d filter.
Parameters and usage are the same.
ow[=depth[:luma_strength[:chroma_strength]]]
Overcomplete Wavelet denoiser.
<depth>
Larger depth values will denoise lower frequency
components more, but slow down filtering (default: 8).
<luma_strength>
luma strength (default: 1.0)
<chroma_strength>
chroma strength (default: 1.0)
eq[=brightness:contrast] (OBSOLETE)
Software equalizer with interactive controls just like the
hardware equalizer, for cards/drivers that do not support
brightness and contrast controls in hardware.
<-100-100>
initial brightness
<-100-100>
initial contrast
eq2[=gamma:contrast:brightness:saturation:rg:gg:bg:weight]
Alternative software equalizer that uses lookup tables (very
slow), allowing gamma correction in addition to simple
brightness and contrast adjustment. Note that it uses the same
MMX optimized code as -vf eq if all gamma values are 1.0. The
parameters are given as floating point values.
<0.1-10>
initial gamma value (default: 1.0)
<-2-2>
initial contrast, where negative values result in a
negative image (default: 1.0)
<-1-1>
initial brightness (default: 0.0)
<0-3>
initial saturation (default: 1.0)
<0.1-10>
gamma value for the red component (default: 1.0)
<0.1-10>
gamma value for the green component (default: 1.0)
<0.1-10>
gamma value for the blue component (default: 1.0)
<0-1>
The weight parameter can be used to reduce the effect of
a high gamma value on bright image areas, e.g. keep them
from getting overamplified and just plain white. A
value of 0.0 turns the gamma correction all the way down
while 1.0 leaves it at its full strength (default: 1.0).
hue[=hue:saturation]
Software equalizer with interactive controls just like the
hardware equalizer, for cards/drivers that do not support hue
and saturation controls in hardware.
<-180-180>
initial hue (default: 0.0)
<-100-100>
initial saturation, where negative values result in a
negative chroma (default: 1.0)
halfpack[=f]
Convert planar YUV 4:2:0 to half-height packed 4:2:2,
downsampling luma but keeping all chroma samples. Useful for
output to low-resolution display devices when hardware
downscaling is poor quality or is not available. Can also be
used as a primitive luma-only deinterlacer with very low CPU
usage.
<f>
By default, halfpack averages pairs of lines when
downsampling. Any value different from 0 or 1 gives the
default (averaging) behavior.
0: Only use even lines when downsampling.
1: Only use odd lines when downsampling.
ilpack[=mode]
When interlaced video is stored in YUV 4:2:0 formats, chroma
interlacing does not line up properly due to vertical
downsampling of the chroma channels. This filter packs the
planar 4:2:0 data into YUY2 (4:2:2) format with the chroma lines
in their proper locations, so that in any given scanline, the
luma and chroma data both come from the same field.
<mode>
Select the sampling mode.
0: nearest-neighbor sampling, fast but incorrect
1: linear interpolation (default)
decimate[=max:hi:lo:frac]
Drops frames that do not differ greatly from the previous frame
in order to reduce framerate. The main use of this filter is
for very-low-bitrate encoding (e.g. streaming over dialup
modem), but it could in theory be used for fixing movies that
were inverse-telecined incorrectly.
<max>
Sets the maximum number of consecutive frames which can
be dropped (if positive), or the minimum interval
between dropped frames (if negative).
<hi>,<lo>,<frac>
A frame is a candidate for dropping if no 8x8 region
differs by more than a threshold of <hi>, and if not
more than <frac> portion (1 meaning the whole image)
differs by more than a threshold of <lo>. Values of
<hi> and <lo> are for 8x8 pixel blocks and represent
actual pixel value differences, so a threshold of 64
corresponds to 1 unit of difference for each pixel, or
the same spread out differently over the block.
dint[=sense:level]
The drop-deinterlace (dint) filter detects and drops the first
from a set of interlaced video frames.
<0.0-1.0>
relative difference between neighboring pixels (default:
0.1)
<0.0-1.0>
What part of the image has to be detected as interlaced
to drop the frame (default: 0.15).
lavcdeint (OBSOLETE)
FFmpeg deinterlacing filter, same as -vf pp=fd
kerndeint[=thresh[:map[:order[:sharp[:twoway]]]]]
Donald Graft's adaptive kernel deinterlacer. Deinterlaces parts
of a video if a configurable threshold is exceeded.
<0-255>
threshold (default: 10)
<map>
0: Ignore pixels exceeding the threshold (default).
1: Paint pixels exceeding the threshold white.
<order>
0: Leave fields alone (default).
1: Swap fields.
<sharp>
0: Disable additional sharpening (default).
1: Enable additional sharpening.
<twoway>
0: Disable twoway sharpening (default).
1: Enable twoway sharpening.
unsharp[=l|cWxH:amount[:l|cWxH:amount]]
unsharp mask / gaussian blur
l
Apply effect on luma component.
c
Apply effect on chroma components.
<width>x<height>
width and height of the matrix, odd sized in both
directions (min = 3x3, max = 13x11 or 11x13, usually
something between 3x3 and 7x7)
amount
Relative amount of sharpness/blur to add to the image (a
sane range should be -1.5-1.5).
<0: blur
>0: sharpen
swapuv
Swap U & V plane.
il[=d|i][s][:[d|i][s]]
(De)interleaves lines. The goal of this filter is to add the
ability to process interlaced images pre-field without
deinterlacing them. You can filter your interlaced DVD and play
it on a TV without breaking the interlacing. While
deinterlacing (with the postprocessing filter) removes
interlacing permanently (by smoothing, averaging, etc)
deinterleaving splits the frame into 2 fields (so called half
pictures), so you can process (filter) them independently and
then re-interleave them.
d deinterleave (placing one above the other)
i interleave
s swap fields (exchange even & odd lines)
fil[=i|d]
(De)interleaves lines. This filter is very similar to the il
filter but much faster, the main disadvantage is that it does
not always work. Especially if combined with other filters it
may produce randomly messed up images, so be happy if it works
but do not complain if it does not for your combination of
filters.
d Deinterleave fields, placing them side by side.
i Interleave fields again (reversing the effect of fil=d).
field[=n]
Extracts a single field from an interlaced image using stride
arithmetic to avoid wasting CPU time. The optional argument n
specifies whether to extract the even or the odd field
(depending on whether n is even or odd).
detc[=var1=value1:var2=value2:...]
Attempts to reverse the 'telecine' process to recover a clean,
non-interlaced stream at film framerate. This was the first and
most primitive inverse telecine filter to be added to MPlayer.
It works by latching onto the telecine 3:2 pattern and following
it as long as possible. This makes it suitable for perfectly-
telecined material, even in the presence of a fair degree of
noise, but it will fail in the presence of complex post-telecine
edits. Development on this filter is no longer taking place, as
ivtc, pullup, and filmdint are better for most applications.
The following arguments (see syntax above) may be used to
control detc's behavior:
<dr>
Set the frame dropping mode.
0: Do not drop frames to maintain fixed output
framerate (default).
1: Always drop a frame when there have been no drops
or telecine merges in the past 5 frames.
2: Always maintain exact 5:4 input to output frame
ratio.
<am>
Analysis mode.
0: Fixed pattern with initial frame number specified
by <fr>.
1: aggressive search for telecine pattern (default)
<fr>
Set initial frame number in sequence. 0-2 are the three
clean progressive frames; 3 and 4 are the two interlaced
frames. The default, -1, means 'not in telecine
sequence'. The number specified here is the type for
the imaginary previous frame before the movie starts.
<t0>, <t1>, <t2>, <t3>
Threshold values to be used in certain modes.
ivtc[=1]
Experimental 'stateless' inverse telecine filter. Rather than
trying to lock on to a pattern like the detc filter does, ivtc
makes its decisions independently for each frame. This will
give much better results for material that has undergone heavy
editing after telecine was applied, but as a result it is not as
forgiving of noisy input, for example TV capture. The optional
parameter (ivtc=1) corresponds to the dr=1 option for the detc
filter, and should not be used with MPlayer. Further
development on ivtc has stopped, as the pullup and filmdint
filters appear to be much more accurate.
pullup[=jl:jr:jt:jb:sb:mp]
Third-generation pulldown reversal (inverse telecine) filter,
capable of handling mixed hard-telecine, 24000/1001 fps
progressive, and 30000/1001 fps progressive content. The pullup
filter is designed to be much more robust than detc or ivtc, by
taking advantage of future context in making its decisions.
Like ivtc, pullup is stateless in the sense that it does not
lock onto a pattern to follow, but it instead looks forward to
the following fields in order to identify matches and rebuild
progressive frames. It is still under development, but believed
to be quite accurate.
jl, jr, jt, and jb
These options set the amount of "junk" to ignore at the
left, right, top, and bottom of the image, respectively.
Left/right are in units of 8 pixels, while top/bottom
are in units of 2 lines. The default is 8 pixels on
each side.
sb (strict breaks)
Setting this option to 1 will reduce the chances of
pullup generating an occasional mismatched frame, but it
may also cause an excessive number of frames to be
dropped during high motion sequences. Conversely,
setting it to -1 will make pullup match fields more
easily. This may help processing of video where there
is slight blurring between the fields, but may also
cause there to be interlaced frames in the output.
mp (metric plane)
This option may be set to 1 or 2 to use a chroma plane
instead of the luma plane for doing pullup's
computations. This may improve accuracy on very clean
source material, but more likely will decrease accuracy,
especially if there is chroma noise (rainbow effect) or
any grayscale video. The main purpose of setting mp to
a chroma plane is to reduce CPU load and make pullup
usable in realtime on slow machines.
filmdint[=options]
Inverse telecine filter, similar to the pullup filter above. It
is designed to handle any pulldown pattern, including mixed soft
and hard telecine and limited support for movies that are slowed
down or sped up from their original framerate for TV. Only the
luma plane is used to find the frame breaks. If a field has no
match, it is deinterlaced with simple linear approximation. If
the source is MPEG-2, this must be the first filter to allow
access to the field-flags set by the MPEG-2 decoder. Depending
on the source MPEG, you may be fine ignoring this advice, as
long as you do not see lots of "Bottom-first field" warnings.
With no options it does normal inverse telecine. When this
filter is used with MPlayer, it will result in an uneven
framerate during playback, but it is still generally better than
using pp=lb or no deinterlacing at all. Multiple options can be
specified separated by /.
crop=<w>:<h>:<x>:<y>
Just like the crop filter, but faster, and works on
mixed hard and soft telecined content as well as when y
is not a multiple of 4. If x or y would require
cropping fractional pixels from the chroma planes, the
crop area is extended. This usually means that x and y
must be even.
io=<ifps>:<ofps>
For each ifps input frames the filter will output ofps
frames. This could be used to filter movies that are
broadcast on TV at a frame rate different from their
original framerate.
luma_only=<n>
If n is nonzero, the chroma plane is copied unchanged.
This is useful for YV12 sampled TV, which discards one
of the chroma fields.
mmx2=<n>
On x86, if n=1, use MMX2 optimized functions, if n=2,
use 3DNow! optimized functions, otherwise, use plain C.
If this option is not specified, MMX2 and 3DNow! are
auto-detected, use this option to override auto-
detection.
fast=<n>
The larger n will speed up the filter at the expense of
accuracy. The default value is n=3. If n is odd, a
frame immediately following a frame marked with the
REPEAT_FIRST_FIELD MPEG flag is assumed to be
progressive, thus filter will not spend any time on
soft-telecined MPEG-2 content. This is the only effect
of this flag if MMX2 or 3DNow! is available. Without
MMX2 and 3DNow, if n=0 or 1, the same calculations will
be used as with n=2 or 3. If n=2 or 3, the number of
luma levels used to find the frame breaks is reduced
from 256 to 128, which results in a faster filter
without losing much accuracy. If n=4 or 5, a faster,
but much less accurate metric will be used to find the
frame breaks, which is more likely to misdetect high
vertical detail as interlaced content.
verbose=<n>
If n is nonzero, print the detailed metrics for each
frame. Useful for debugging.
dint_thres=<n>
Deinterlace threshold. Used during de-interlacing of
unmatched frames. Larger value means less
deinterlacing, use n=256 to completely turn off
deinterlacing. Default is n=8.
comb_thres=<n>
Threshold for comparing a top and bottom fields.
Defaults to 128.
diff_thres=<n>
Threshold to detect temporal change of a field. Default
is 128.
sad_thres=<n>
Sum of Absolute Difference threshold, default is 64.
divtc[=options]
Inverse telecine for deinterlaced video. If 3:2-pulldown
telecined video has lost one of the fields or is deinterlaced
using a method that keeps one field and interpolates the other,
the result is a juddering video that has every fourth frame
duplicated. This filter is intended to find and drop those
duplicates and restore the original film framerate. Two
different modes are available: One pass mode is the default and
is straightforward to use, but has the disadvantage that any
changes in the telecine phase (lost frames or bad edits) cause
momentary judder until the filter can resync again. Two pass
mode avoids this by analyzing the whole video beforehand so it
will have forward knowledge about the phase changes and can
resync at the exact spot. These passes do not correspond to
pass one and two of the encoding process. You must run an extra
pass using divtc pass one before the actual encoding throwing
the resulting video away. Use -nosound -ovc raw -o /dev/null to
avoid wasting CPU power for this pass. You may add something
like crop=2:2:0:0 after divtc to speed things up even more.
Then use divtc pass two for the actual encoding. If you use
multiple encoder passes, use divtc pass two for all of them.
The options are:
pass=1|2
Use two pass mode.
file=<filename>
Set the two pass log filename (default:
"framediff.log").
threshold=<value>
Set the minimum strength the telecine pattern must have
for the filter to believe in it (default: 0.5). This is
used to avoid recognizing false pattern from the parts
of the video that are very dark or very still.
window=<numframes>
Set the number of past frames to look at when searching
for pattern (default: 30). Longer window improves the
reliability of the pattern search, but shorter window
improves the reaction time to the changes in the
telecine phase. This only affects the one pass mode.
The two pass mode currently uses fixed window that
extends to both future and past.
phase=0|1|2|3|4
Sets the initial telecine phase for one pass mode
(default: 0). The two pass mode can see the future, so
it is able to use the correct phase from the beginning,
but one pass mode can only guess. It catches the
correct phase when it finds it, but this option can be
used to fix the possible juddering at the beginning.
The first pass of the two pass mode also uses this, so
if you save the output from the first pass, you get
constant phase result.
deghost=<value>
Set the deghosting threshold (0-255 for one pass mode,
-255-255 for two pass mode, default 0). If nonzero,
deghosting mode is used. This is for video that has
been deinterlaced by blending the fields together
instead of dropping one of the fields. Deghosting
amplifies any compression artifacts in the blended
frames, so the parameter value is used as a threshold to
exclude those pixels from deghosting that differ from
the previous frame less than specified value. If two
pass mode is used, then negative value can be used to
make the filter analyze the whole video in the beginning
of pass-2 to determine whether it needs deghosting or
not and then select either zero or the absolute value of
the parameter. Specify this option for pass-2, it makes
no difference on pass-1.
phase[=t|b|p|a|u|T|B|A|U][:v]
Delay interlaced video by one field time so that the field order
changes. The intended use is to fix PAL movies that have been
captured with the opposite field order to the film-to-video
transfer. The options are:
t Capture field order top-first, transfer bottom-first.
Filter will delay the bottom field.
b Capture bottom-first, transfer top-first. Filter will
delay the top field.
p Capture and transfer with the same field order. This
mode only exists for the documentation of the other
options to refer to, but if you actually select it, the
filter will faithfully do nothing ;-)
a Capture field order determined automatically by field
flags, transfer opposite. Filter selects among t and b
modes on a frame by frame basis using field flags. If
no field information is available, then this works just
like u.
u Capture unknown or varying, transfer opposite. Filter
selects among t and b on a frame by frame basis by
analyzing the images and selecting the alternative that
produces best match between the fields.
T Capture top-first, transfer unknown or varying. Filter
selects among t and p using image analysis.
B Capture bottom-first, transfer unknown or varying.
Filter selects among b and p using image analysis.
A Capture determined by field flags, transfer unknown or
varying. Filter selects among t, b and p using field
flags and image analysis. If no field information is
available, then this works just like U. This is the
default mode.
U Both capture and transfer unknown or varying. Filter
selects among t, b and p using image analysis only.
v Verbose operation. Prints the selected mode for each
frame and the average squared difference between fields
for t, b, and p alternatives.
telecine[=start]
Apply 3:2 'telecine' process to increase framerate by 20%. This
most likely will not work correctly with MPlayer. The optional
start parameter tells the filter where in the telecine pattern
to start (0-3).
tinterlace[=mode]
Temporal field interlacing - merge pairs of frames into an
interlaced frame, halving the framerate. Even frames are moved
into the upper field, odd frames to the lower field. This can
be used to fully reverse the effect of the tfields filter (in
mode 0). Available modes are:
0 Move odd frames into the upper field, even into the
lower field, generating a full-height frame at half
framerate.
1 Only output odd frames, even frames are dropped; height
unchanged.
2 Only output even frames, odd frames are dropped; height
unchanged.
3 Expand each frame to full height, but pad alternate
lines with black; framerate unchanged.
4 Interleave even lines from even frames with odd lines
from odd frames. Height unchanged at half framerate.
tfields[=mode[:field_dominance]]
Temporal field separation - split fields into frames, doubling
the output framerate.
<mode>
0: Leave fields unchanged (will jump/flicker).
1: Interpolate missing lines. (The algorithm used might
not be so good.)
2: Translate fields by 1/4 pixel with linear
interpolation (no jump).
4: Translate fields by 1/4 pixel with 4tap filter
(higher quality) (default).
<field_dominance> (DEPRECATED)
-1: auto (default) Only works if the decoder exports the
appropriate information and no other filters which
discard that information come before tfields in the
filter chain, otherwise it falls back to 0 (top field
first).
0: top field first
1: bottom field first
NOTE: This option will possibly be removed in a future
version. Use -field-dominance instead.
yadif=[mode[:field_dominance]]
Yet another deinterlacing filter
<mode>
0: Output 1 frame for each frame.
1: Output 1 frame for each field.
2: Like 0 but skips spatial interlacing check.
3: Like 1 but skips spatial interlacing check.
<field_dominance> (DEPRECATED)
Operates like tfields.
NOTE: This option will possibly be removed in a future
version. Use -field-dominance instead.
mcdeint=[mode[:parity[:qp]]]
Motion compensating deinterlacer. It needs one field per frame
as input and must thus be used together with tfields=1 or
yadif=1/3 or equivalent.
<mode>
0: fast
1: medium
2: slow, iterative motion estimation
3: extra slow, like 2 plus multiple reference frames
<parity>
0 or 1 selects which field to use (note: no
autodetection yet!).
<qp>
Higher values should result in a smoother motion vector
field but less optimal individual vectors.

Scale and smooth the image with the 2x scale and interpolate
algorithm.
1bpp
1bpp bitmap to YUV/BGR 8/15/16/32 conversion
down3dright[=lines]
Reposition and resize stereoscopic images. Extracts both stereo
fields and places them side by side, resizing them to maintain
the original movie aspect.
<lines>
number of lines to select from the middle of the image
(default: 12)
bmovl=hidden:opaque:fifo
The bitmap overlay filter reads bitmaps from a FIFO and displays
them on top of the movie, allowing some transformations on the
image. Also see TOOLS/bmovl-test.c for a small bmovl test
program.
<hidden>
Set the default value of the 'hidden' flag (0=visible,
1=hidden).
<opaque>
Set the default value of the 'opaque' flag
(0=transparent, 1=opaque).
<fifo>
path/filename for the FIFO (named pipe connecting
'mplayer -vf bmovl' to the controlling application)
FIFO commands are:
RGBA32 width height xpos ypos alpha clear
followed by width*height*4 Bytes of raw RGBA32 data.
ABGR32 width height xpos ypos alpha clear
followed by width*height*4 Bytes of raw ABGR32 data.
RGB24 width height xpos ypos alpha clear
followed by width*height*3 Bytes of raw RGB24 data.
BGR24 width height xpos ypos alpha clear
followed by width*height*3 Bytes of raw BGR24 data.
ALPHA width height xpos ypos alpha
Change alpha transparency of the specified area.
CLEAR width height xpos ypos
Clear area.
OPAQUE
Disable all alpha transparency. Send "ALPHA 0 0 0 0 0"
to enable it again.
HIDE
Hide bitmap.
SHOW
Show bitmap.
Arguments are:
<width>, <height>
image/area size
<xpos>, <ypos>
Start blitting at position x/y.
<alpha>
Set alpha difference. If you set this to -255 you can
then send a sequence of ALPHA-commands to set the area
to -225, -200, -175 etc for a nice fade-in-effect! ;)
0: same as original
255: Make everything opaque.
-255: Make everything transparent.
<clear>
Clear the framebuffer before blitting.
0: The image will just be blitted on top of the old
one, so you do not need to send 1.8MB of RGBA32 data
every time a small part of the screen is updated.
1: clear
framestep=I|[i]step
Renders only every nth frame or every intra frame (keyframe).
If you call the filter with I (uppercase) as the parameter, then
only keyframes are rendered. For DVDs it generally means one in
every 15/12 frames (IBBPBBPBBPBBPBB), for AVI it means every
scene change or every keyint value.
When a keyframe is found, an 'I!' string followed by a newline
character is printed, leaving the current line of MPlayer output
on the screen, because it contains the time (in seconds) and
frame number of the keyframe (You can use this information to
split the AVI.).
If you call the filter with a numeric parameter 'step' then only
one in every 'step' frames is rendered.
If you put an 'i' (lowercase) before the number then an 'I!' is
printed (like the I parameter).
If you give only the i then nothing is done to the frames, only
I! is printed.
tile=xtiles:ytiles:output:start:delta
Tile a series of images into a single, bigger image. If you
omit a parameter or use a value less than 0, then the default
value is used. You can also stop when you are satisfied (...
-vf tile=10:5 ...). It is probably a good idea to put the scale
filter before the tile :-)
The parameters are:
<xtiles>
number of tiles on the x axis (default: 5)
<ytiles>
number of tiles on the y axis (default: 5)
<output>
Render the tile when 'output' number of frames are
reached, where 'output' should be a number less than
xtile * ytile. Missing tiles are left blank. You
could, for example, write an 8 * 7 tile every 50 frames
to have one image every 2 seconds @ 25 fps.
<start>
outer border thickness in pixels (default: 2)
<delta>
inner border thickness in pixels (default: 4)
delogo[=x:y:w:h:t]
Suppresses a TV station logo by a simple interpolation of the
surrounding pixels. Just set a rectangle covering the logo and
watch it disappear (and sometimes something even uglier appear -
your mileage may vary).
<x>,<y>
top left corner of the logo
<w>,<h>
width and height of the cleared rectangle
<t> Thickness of the fuzzy edge of the rectangle (added to w
and h). When set to -1, a green rectangle is drawn on
the screen to simplify finding the right x,y,w,h
parameters.
file=<file>
You can specify a text file to load the coordinates
from. Each line must have a timestamp (in seconds, and
in ascending order) and the "x:y:w:h:t" coordinates (t
can be omitted).
remove-logo=/path/to/logo_bitmap_file_name.pgm
Suppresses a TV station logo, using a PGM or PPM image file to
determine which pixels comprise the logo. The width and height
of the image file must match those of the video stream being
processed. Uses the filter image and a circular blur algorithm
to remove the logo.
/path/to/logo_bitmap_file_name.pgm
[path] + filename of the filter image.
screenshot
Allows acquiring screenshots of the movie using slave mode
commands that can be bound to keypresses. See the slave mode
documentation and the INTERACTIVE CONTROL section for details.
Files named 'shotNNNN.png' will be saved in the working
directory, using the first available number - no files will be
overwritten. The filter has no overhead when not used and
accepts an arbitrary colorspace, so it is safe to add it to the
configuration file. Make sure that the screenshot filter is
added after all other filters whose effect you want to record on
the saved image. E.g. it should be the last filter if you want
to have an exact screenshot of what you see on the monitor.
ass
Moves SSA/ASS subtitle rendering to an arbitrary point in the
filter chain. Only useful with the -ass option.
EXAMPLE:
-vf ass,screenshot
Moves SSA/ASS rendering before the screenshot filter.
Screenshots taken this way will contain subtitles.
blackframe[=amount:threshold]
Detect frames that are (almost) completely black. Can be useful
to detect chapter transitions or commercials. Output lines
consist of the frame number of the detected frame, the
percentage of blackness, the frame type and the frame number of
the last encountered keyframe.
<amount>
Percentage of the pixels that have to be below the
threshold (default: 98).
<threshold>
Threshold below which a pixel value is considered black
(default: 32).
stereo3d[=in:out]
Stereo3d converts between different stereoscopic image formats.
<in> Stereoscopic image format of input. Possible values:
sbsl or side_by_side_left_first
side by side parallel (left eye left, right eye
right)
sbsr or side_by_side_right_first
side by side crosseye (right eye left, left eye
right)
abl or above_below_left_first
above-below (left eye above, right eye below)
abl or above_below_right_first
above-below (right eye above, left eye below)
ab2l or above_below_half_height_left_first
above-below with half height resolution (left eye
above, right eye below)
ab2r or above_below_half_height_right_first
above-below with half height resolution (right
eye above, left eye below)
<out>
Stereoscopic image format of output. Possible values are
all the input formats as well as:
arcg or anaglyph_red_cyan_gray
anaglyph red/cyan gray (red filter on left eye,
cyan filter on right eye)
arch or anaglyph_red_cyan_half_color
anaglyph red/cyan half colored (red filter on
left eye, cyan filter on right eye)
arcc or anaglyph_red_cyan_color
anaglyph red/cyan color (red filter on left eye,
cyan filter on right eye)
arcd or anaglyph_red_cyan_dubois
anaglyph red/cyan color optimized with the least
squares projection of dubois (red filter on left
eye, cyan filter on right eye)
agmg or anaglyph_green_magenta_gray
anaglyph green/magenta gray (green filter on left
eye, magenta filter on right eye)
agmh or anaglyph_green_magenta_half_color
anaglyph green/magenta half colored (green filter
on left eye, magenta filter on right eye)
agmc or anaglyph_green_magenta_color
anaglyph green/magenta colored (green filter on
left eye, magenta filter on right eye)
aybg or anaglyph_yellow_blue_gray
anaglyph yellow/blue gray (yellow filter on left
eye, blue filter on right eye)
aybh or anaglyph_yellow_blue_half_color
anaglyph yellow/blue half colored (yellow filter
on left eye, blue filter on right eye)
aybc or anaglyph_yellow_blue_color
anaglyph yellow/blue colored (yellow filter on
left eye, blue filter on right eye)
irl or interleave_rows_left_first
Interleaved rows (left eye has top row, right eye
starts on next row)
irr or interleave_rows_right_first
Interleaved rows (right eye has top row, left eye
starts on next row)
ml or mono_left
mono output (left eye only)
mr or mono_right
mono output (right eye only)
NOTE: To use either of the interleaved-rows output formats to
display full-screen on a row-interleaved 3D display, you will
need to scale the video to the correct height first using the
"scale" filter, if it is not already the right height.
Typically, that is 1080 rows (so use e.g. "-vf
scale=1440:1080,stereo3d=sbsl:irl" for a 720p side-by-side
encoded movie).
gradfun[=strength[:radius]]
Fix the banding artifacts that are sometimes introduced into
nearly flat regions by truncation to 8bit colordepth.
Interpolates the gradients that should go where the bands are,
and dithers them.
This filter is designed for playback only. Do not use it prior
to lossy compression, because compression tends to lose the
dither and bring back the bands.
<strength>
Maximum amount by which the filter will change any one
pixel. Also the threshold for detecting nearly flat
regions (default: 1.2).
<radius>
Neighborhood to fit the gradient to. Larger radius
makes for smoother gradients, but also prevents the
filter from modifying pixels near detailed regions
(default: 16).
fixpts[=options]
Fixes the presentation timestamps (PTS) of the frames. By
default, the PTS passed to the next filter is dropped, but the
following options can change that:
print
Print the incoming PTS.
fps=<fps>
Specify a frame per second value.
start=<pts>
Specify an initial value for the PTS.
autostart=<n>
Uses the nth incoming PTS as the initial PTS. All
previous PTS are kept, so setting a huge value or -1
keeps the PTS intact.
autofps=<n>
Uses the nth incoming PTS after the end of autostart to
determine the framerate.
EXAMPLE:
-vf fixpts=fps=24000/1001,ass,fixpts
Generates a new sequence of PTS, uses it for ASS
subtitles, then drops it. Generating a new sequence is
useful when the timestamps are reset during the program;
this is frequent on DVDs. Dropping it may be necessary
to avoid confusing encoders.
NOTE: Using this filter together with any sort of seeking
(including -ss and EDLs) may make demons fly out of your nose.
ENVIRONMENT VARIABLES
There are a number of environment variables that can be used to control
the behavior of MPlayer.
MPLAYER_CHARSET (also see -msgcharset)
Convert console messages to the specified charset (default:
autodetect). A value of "noconv" means no conversion.
MPLAYER_HOME
Directory where MPlayer looks for user settings.
MPLAYER_LOCALEDIR
Directory where MPlayer looks for gettext translation files (if
enabled).
MPLAYER_VERBOSE (also see -v and -msglevel)
Set the initial verbosity level across all message modules
(default: 0). The resulting verbosity corresponds to that of
-msglevel 5 plus the value of MPLAYER_VERBOSE.
libaf:
LADSPA_PATH
If LADSPA_PATH is set, it searches for the specified file. If
it is not set, you must supply a fully specified pathname.
FIXME: This is also mentioned in the ladspa section.
libdvdcss:
DVDCSS_CACHE
Specify a directory in which to store title key values. This
will speed up descrambling of DVDs which are in the cache. The
DVDCSS_CACHE directory is created if it does not exist, and a
subdirectory is created named after the DVD's title or
manufacturing date. If DVDCSS_CACHE is not set or is empty,
libdvdcss will use the default value which is "${HOME}/.dvdcss/"
under Unix and "C:\Documents and Settings\$USER\Application
Data\dvdcss\" under Win32. The special value "off" disables
caching.
DVDCSS_METHOD
Sets the authentication and decryption method that libdvdcss
will use to read scrambled discs. Can be one of title, key or
disc.
key
is the default method. libdvdcss will use a set of
calculated player keys to try and get the disc key.
This can fail if the drive does not recognize any of the
player keys.
disc
is a fallback method when key has failed. Instead of
using player keys, libdvdcss will crack the disc key
using a brute force algorithm. This process is CPU
intensive and requires 64 MB of memory to store
temporary data.
title
is the fallback when all other methods have failed. It
does not rely on a key exchange with the DVD drive, but
rather uses a crypto attack to guess the title key. On
rare cases this may fail because there is not enough
encrypted data on the disc to perform a statistical
attack, but in the other hand it is the only way to
decrypt a DVD stored on a hard disc, or a DVD with the
wrong region on an RPC2 drive.
DVDCSS_RAW_DEVICE
Specify the raw device to use. Exact usage will depend on your
operating system, the Linux utility to set up raw devices is
raw(8) for instance. Please note that on most operating
systems, using a raw device requires highly aligned buffers:
Linux requires a 2048 bytes alignment (which is the size of a
DVD sector).
DVDCSS_VERBOSE
Sets the libdvdcss verbosity level.
0 Outputs no messages at all.
1 Outputs error messages to stderr.
2 Outputs error messages and debug messages to stderr.
DVDREAD_NOKEYS
Skip retrieving all keys on startup. Currently disabled.
HOME FIXME: Document this.
libao2:
AO_SUN_DISABLE_SAMPLE_TIMING
FIXME: Document this.
AUDIODEV
FIXME: Document this.
AUDIOSERVER
Specifies the Network Audio System server to which the nas audio
output driver should connect and the transport that should be
used. If unset DISPLAY is used instead. The transport can be
one of tcp and unix. Syntax is tcp/<somehost>:<someport>,
<somehost>:<instancenumber> or [unix]:<instancenumber>. The NAS
base port is 8000 and <instancenumber> is added to that.
EXAMPLES:
AUDIOSERVER=somehost:0
Connect to NAS server on somehost using default port and
transport.
AUDIOSERVER=tcp/somehost:8000
Connect to NAS server on somehost listening on TCP port
8000.
AUDIOSERVER=(unix)?:0
Connect to NAS server instance 0 on localhost using unix
domain sockets.

mplayer dummy.avi -sub source.sub -dumpmpsub
Convert subtitles to MPsub format without watching the movie:
mplayer /dev/zero -rawvideo pal:fps=xx -demuxer rawvideo -vc null -vo null -noframedrop -benchmark -sub source.sub -dumpmpsub
input from standard V4L:
mplayer tv:// -tv driver=v4l:width=640:height=480:outfmt=i420 -vc rawi420 -vo xv
Play DTS-CD with passthrough:
mplayer -ac hwdts -rawaudio format=0x2001 -cdrom-device /dev/cdrom cdda://
You can also use -afm hwac3 instead of -ac hwdts. Adjust '/dev/cdrom'
to match the CD-ROM device on your system. If your external receiver
supports decoding raw DTS streams, you can directly play it via cdda://
without setting format, hwac3 or hwdts.

mplayer -rawaudio format=0xff -demuxer rawaudio -af pan=2:.32:.32:.39:.06:.06:.39:.17:-.17:-.17:.17:.33:.33 adts_he-aac160_51.aac
You might want to play a bit with the pan values (e.g multiply with a
value) to increase volume or avoid clipping.
checkerboard invert with geq filter:
mplayer -vf geq='128+(p(X\,Y)-128)*(0.5-gt(mod(X/SW\,128)\,64))*(0.5-gt(mod(Y/SH\,128)\,64))*4'
