Ubuntu Manpage: xjadeo - X Jack Video Monitor

NAME

       xjadeo - X Jack Video Monitor

SYNOPSIS

       xjadeo [ OPTIONS ] [ video-file ]

DESCRIPTION

       xjadeo - the X Jack Video Monitor

       Xjadeo  is  a  software  video  player that displays a video clip synchronized to an external time source
       (MTC, LTC, JACK transport).

       Xjadeo is intended for soundtrack composition, video monitoring and useful for any task that requires  to
       synchronizing movie frames with audio events.

OPTIONS

-A, --avverbose
Display verbose video decoder messages.

-a, --ontop
Keep xjadeo window on top of other applications.

-b, --no-letterbox
Scale movie to fit window. Without this option a letterbox is used to retain the aspect ratio.

-D, --debug
Print development related information.

-d <name>, --midi-driver <name>
Specify midi driver to use. Run 'xjadeo -V' to list supported driver(s). <name> is case
insensitive and can be shortened to the first unique name. eg '-d j' for jack, '-d alsa-r' for
alsa-raw

-f <val>, --screen-fps <val>
Desired refresh rate of the video display in frames If this value is equal or less than zero,
xjadeo will use the FPS of the video file as its update frequency (which is the default). Note:
This does not affect screen/vblank sync. Synchronizing to the screen's vertical refresh is
hardware dependent (and always used if available).

-h, --help
Display this help and exit.

-I, --ignore-file-offset
This option is only useful for video files with a start offset, such as split vob files. Per
default xjadeo honors offsets specified in the video file header. This option allows one to
override (and subtract) this offset to align the start of the file with timecode 00:00:00:00.

-i <int>, --info <int>
Display time information using the OSD (on screen display). 0:Off, 1: Frame number, 2: Timecode,
3: both.

-J, --no-initial-sync
Do not connect to JACK, nor use any other sync source at application start.

-K <int>, --keyframe-limit <int>
Specify a maximum key-frame interval limit. With most video codecs, a video frame is the sum of a
key-frame plus differences from the closest key-frame. For non continuous playback and random
seeks xjadeo will have to go back to a key-frame and decode sequentially to the target frame.
This can be quite CPU intense and hence the max. sequential decoding sequence is limited. By
default to 100 frames For fast frame accurate seeks, it is highly recommended to transcode the
video file using a codec where every frame is a key-frame (eg. mjpeg), and the video consists only
of "intra" frames. (the key-frame interval is sometimes also called "group of pictures"s or GOP).

-l, --ltc
Sync to Linear Time Code (audio jack).

-M <int>, --midifps <int>
Specify MTC conversion mode:

0: use frame-rate from MTC clock (default)

1: use video file's fps

2: "resample" file's fps / MTC

-m <port>, --midi <port>
Use MTC as sync source The <port> argument is midi driver specific:

jack-midi:
specify a midi port name to connect to,

or "" to not auto connect.
alsa-seq: specify ID to connect to (-1: none)

eg. -m ardour or -m 80
alsa-raw: specify hardware device

eg. -m hw:1,0 or -m 1
portmidi: numeric id; -1: autodetect

a value > -1 specifies the port number to use.
use '-v -m -1' to list midi ports.

-O <port>, --osc <port>
Listen for OSC messages on the given port. Xjadeo can be remote controlled using Open Sound
Control. For a list of available commands, please see the source code or online documentation.

-o <val>, --offset <val>
Time offset video from timecode source. This allows one to offset the video playback a certain
number of (video) frames relative to the time source. Positive and negative values are permitted.
The offset van be specified either as integer frame number of as colon separated timecode.

--osc-doc
Print available OSC commands and exit.

-Q, --mq
Enable POSIX realtime message queues. This sets up a communication channel for remote, intended
to be used with `xjremote`.

-q, --quiet, --silent
inhibit usual output.

-R, --remote
Enable interactive remote control mode using standard I/O. This option implies non-verbose and
quiet as the terminal is used for interaction.

-r <file>, --rc <file>
Specify a custom configuration file to load.

-S, --no-splash
Skip the on screen display startup sequence.

-s, --fullscreen
Start xjadeo in full screen mode.

-T <file>, --ttf-file <file>
path to .ttf font for on screen display

-U, --uuid
specify JACK SESSION UUID.

-V, --version
Print version information and exit.

-W <rpc-id>, --ipc <rpc-id>
Setup IPC message queues for remote control Inter Process Communication is used by `xjremote` on
OSX and other platforms that do not support realtime message queues

-v, --verbose
print more information

-x <int>, --vo <int>, --videomode <int>
Select a video output mode (default: 0: autodetect) A value of -1 lists the available mode and
exits

Synchronization Sources:

       JACK:  JACK transport

       LTC:   Linear/Longitudinal Time Code - via JACK audio

       MTC:   MIDI Time Code via JACK MIDI

       MTC:   MIDI Time Code via ALSA sequencer (Linux only)

       MTC:   MIDI Time Code via ALSA raw devices (Linux only)

       MTC:   MIDI Time Code via portmidi (OSX, Windows)

       Manual:
              Remote controlled manual seeks.

       If neither -m nor -l options are given, xjadeo synchronizes to jack transport by default.

Video Codecs and Formats:

       Xjadeo uses ffmpeg to decode video files, so a wide range of  formats  and  codecs  are  supported.  Note
       however  that  not  all  the  codecs support reliable seeking.  It is highly recommended to transcode the
       video file into a suitable  format/codec.  The  recommend  combination  is  avi/mjpeg.   e.g.  ffmpeg  -i
       input-file.xxx  -an  -vcodec  mjpeg  output-file.avi  This  creates from your input-file.xxx an AVI mjpeg
       encoded video file without sound, and no compression between frames (motion  jpeg  -  every  frame  is  a
       key-frame).  You  may  want  also  to shrink the size of the file by scaling down its geometry. This uses
       fewer system resources for decoding and display and leaves more  space  on  the  screen  for  your  audio
       software.   see ffmpeg -s <width>x<height> option and read up on the ffmpeg man page for further options.
       e.g. -qscale 0 to retain image quality.

Configuration Files:

       At startup xjadeo reads the following resource configuration files in the following order:

       system wide:
              /etc/xjadeorc or /usr/local/etc/xjadeorc

       old user config:
              $HOME/.xjadeorc

       user config:
              $XDM_CONFIG_HOME/xjadeo/xjadeorc (usually $HOME/.config/)

       on OSX:
              $HOME/Library/Preferences/xjadeorc

       on Windows:
              $HOMEDRIVE$HOMEPATH\xjadeorc

       and $HOMEDRIVE$HOMEPATH\Local Settings\xjadeorc
              (usually C:\Documents and Settings\<Username>\)

       project specific:
              $PWD/xjadeorc

       Every line in the configuration file is a KEY=VALUE pair. If the first character on a line is either is a
       literal  '#'  or  ';',  the  line is ignored.  KEYS are case insensitive. Boolean values are specified as
       'yes' or 'no'.  As for a list of available keys, please see the  example  configuration  file,  which  is
       available in the documentation folder of the source code.

       If  xjadeo  is compiled with jack session support, it will save its current state as config file and pass
       it as handle to the jack session manager.

User Interaction:

       The xjadeo window offers a right-click context menu (except on OSX where the application has a main  menu
       bar) which provides easy access to common functionality.  On OSX and Windows this menu offers a file open
       dialog to change the video file that is being monitored. On Linux new files can be loaded by dragging the
       file  onto  the  window  itself.   In  addition xjadeo reacts to key presses. The following shortcuts are
       defined:

       'Esc'  Close window and quit

              saturation:7+8 hue:9+0. XV color balance is hardware dependent.

       Note  that  it is possible to disable certain features using the remote control.  A Host can take control
       of certain aspects e.g. offset or disallow closing the video monitor, except by host-provided means.
