       ogg123 - plays Ogg Vorbis files


       ogg123 [ -vqrzZVh ] [ -k seconds ] [ -x nth ] [ -y ntimes ] [ -b buffer_size ] [ -d driver
       [ -o option:value ] [ -f filename ] ] file ...  | directory ...  | URL ...


       ogg123 reads Ogg Vorbis audio files and decodes them  to  the  devices  specified  on  the
       command  line.   By default, ogg123 writes to the standard sound device, but output can be
       sent to any number of devices.  Files can be read from the file system,  or  URLs  can  be
       streamed  via HTTP.  If a directory is given, all of the files in it or its subdirectories
       will be played.


       --audio-buffer n
              Use an output audio buffer of approximately 'n' kilobytes.

       -@ playlist, --list playlist
              Play all of the files named in the file 'playlist'.  The playlist should  have  one
              filename, directory name, or URL per line.  Blank lines are permitted.  Directories
              will be treated in the same way as on the command line.

       -b n, --buffer n
              Use an input buffer of approximately 'n' kilobytes.  HTTP-only option.

       -p n, --prebuffer n
              Prebuffer 'n' percent of  the  input  buffer.   Playback  won't  begin  until  this
              prebuffer is complete.  HTTP-only option.

       -d device, --device device
              Specify  output  device.  See DEVICES section for a list of devices.  Any number of
              devices may be specified.

       -f filename, --file filename
              Specify output file for file devices.  The filename "-" writes to standard out.  If
              the file already exists, ogg123 will overwrite it.

       -h, --help
              Show command help.

       -k n, --skip n
              Skip   the   first   'n'   seconds.    'n'   may  also  be  in  minutes:seconds  or
              hours:minutes:seconds form.

       -K n, --end n
              Stops playing 'n' seconds from the start of the stream.  'n' may also have the same
              format as used in the --skip option.

       -o option[:value], --device-option option[:value]
              Sets  the  option option to value for the preceding device.  See DEVICES for a list
              of valid options for each device.

       -q, --quiet
              Quiet mode.  No messages are displayed.

       -V, --version
              Display version information.

       -v, --verbose
              Increase verbosity.

       -x n, --nth
              Play every 'n'th decoded block.  Has the effect  of  playing  audio  at  'n'  times
              faster than normal speed.

       -y n, --ntimes
              Repeat  every  played  block  'n' times.  Has the effect of playing audio 'n' times
              slower than normal speed.  May be with -x for interesting fractional speeds.

       -r, --repeat
              Repeat playlist indefinitely.

       -z, --shuffle
              Play files in pseudo-random order.

       -Z, --random
              Play files in pseudo-random order forever.


       ogg123 supports a variety of audio output  devices  through  libao.   Only  those  devices
       supported  by  the target platform will be available.  The -f option may only be used with
       devices that write to files.

       Options supported by all devices:

              debug  Turn on debugging output [if any] for a chosen driver.

                     Force a specific output channel ordering for a given  device.   value  is  a
                     comma seperated list of AO style channel names, eg, L,R,C,LFE,BL,BR,SL,SR.

                     Turn  on verbose output for a chosen driver. the -v option will also set the
                     driver verbose option.

              quiet  Force chosen driver to be completely silent.  Even errors will  not  produce
                     any output. -q will also set the driver quiet option.

       aixs   AIX live output driver. Options:

                     Set AIX output device to value

       alsa   Advanced Linux Sound Architecture live output driver. Options:

                     Override the default hardware buffer size (in milliseconds).

                     ALSA  device  label  to use. Examples include "hw:0" for the first soundcard
                     and "hw:1" for  the  second.   The  alsa  driver  normally  chooses  one  of
                     "surround71",   "surround51",   "surround40"   or   "default"  automatically
                     depending  on  number  of  output  channels.   For  more  information,   see

                     Override the default hardware period size (in microseconds).

                     Override the default hardware period size (in microseconds).

                     value  is set to "yes" or "no" to override the compiled-in default to use or
                     not use mmap device access.  In the  past,  some  buggy  alsa  drivers  have
                     behaved  better when not using mmap access at the penalty of slightly higher
                     CPU usage.

       arts   aRts Sound Daemon live output driver. Options:

                     value is set to "yes" or "no" to allow opening the aRts playback device  for
                     multiply  concurrent  playback.  Although the driver works properly in multi
                     mode, it is known to occasionally crash the  aRts  server  itself.   Default
                     behavior is "no".

       au     Sun  audio  file  output.   Writes  the  audio samples in AU format.  The AU format
              supports writing to unseekable files like standard out.  In such circumstances, the
              AU header will specify the sample format, but not the length of the recording.

       esd    Enlightened Sound Daemon live output. Options:

                     value  specifies the hostname where esd is running.  This can include a port
                     number after a colon, as in "".  (Default = localhost)

       irix   IRIX live output audio driver.

       macosx MacOS X 'AUHAL' live output driver.  This driver supports MacOS X  10.5  and  later
              (10.4 and earlier uses an earlier, incompatable interface). Options:

                     Set the hardware buffer size to the equivalent of value milliseconds.

       nas    Network Audio Server live output driver. Options:

                     Set size of audio buffer on server in bytes.

                     Set location of NAS server; See nas(1) for format.

       null   Null  driver.   All  audio  data is discarded.  (Note: Audio data is not written to
              /dev/null !)  You could use this driver to test raw decoding speed  without  output

       oss    Open Sound System driver for Linux and FreeBSD, versions 2, 3 and 4. Options:

                     DSP device for soundcard.  Defaults to /dev/dsp.

       pulse  Pulseaudio live audio sound driver. Options:

                     Specifies location of remote or alternate Pulseaudio server.

                     Specifies a non-default Pulseaudio sink for audio stream.

       raw    Raw file output.  Writes raw audio samples to a file. Options:

                     Chooses  big  endian ("big"), little endian ("little"), or native ("native")
                     byte order.  Default is native order.

       roar   Roar Audio Daemon live output driver. Options:

                     Specifies location of remote Roar server to use.

       sndio  OpenBSD SNDIO live output driver. Options:

                     Specifies audio device to use for playback.

       sun    Sun Audio live output driver for NetBSD, OpenBSD, and Solaris. Options:

                     Audio device for soundcard.  Defaults to /dev/audio.

       wav    WAV file output.  Writes the sound data to disk in uncompressed form.  If  multiple
              files  are  played,  all  of them will be concatenated into the same WAV file.  WAV
              files cannot be written to unseekable files, such as  standard  out.   Use  the  AU
              format instead.

       wmm    Windows MultiMedia live output driver for Win98 and later. Options:

                     Selects audio device to use for playback by device name.

                     Selects audio device to use for playback by device id (card number).


       The  ogg123 command line is fairly flexible, perhaps confusingly so.  Here are some sample
       command lines and an explanation of what they do.

       Play on the default soundcard:
              ogg123 test.ogg

       Play all of the files in the directory ~/music and its subdirectories.
              ogg123 ~/music

       Play a file using the OSS driver:
              ogg123 -d oss test.ogg

       Pass the "dsp" option to the OSS driver:
              ogg123 -d oss -o dsp:/dev/mydsp

       Use the ESD driver
              ogg123 -d esd test.ogg

       Use the WAV driver with the output file, "test.wav":
              ogg123 -d wav -f test.wav test.ogg

       Listen to a file while you write it to a WAV file:
              ogg123 -d oss -d wav -f test.wav test.ogg

       Note that options apply to the device declared to the left:
              ogg123 -d oss -o dsp:/dev/mydsp -d raw -f test2.raw -o byteorder:big test.ogg

       Stress test your harddrive:
              ogg123 -d oss -d wav -f 1.wav -d wav -f 2.wav -d wav -f 3.wav -d wav  -f  4.wav  -d
              wav -f 5.wav test.ogg

       Create an echo effect with esd and a slow computer:
              ogg123 -d esd -d esd test.ogg


       You  can  abort ogg123 at any time by pressing Ctrl-C.  If you are playing multiple files,
       this will stop the current file and begin playing the next one.   If  you  want  to  abort
       playing  immediately  instead  of skipping to the next file, press Ctrl-C within the first
       second of the playback of a new file.

       Note that the result of pressing Ctrl-C might not be audible  immediately,  due  to  audio
       data buffering in the audio device.  This delay is system dependent, but it is usually not
       more than one or two seconds.


              Can be used to set the default output device for all libao programs.

              Per-user config file to override the system wide output device settings.


       Piped WAV files may cause strange behavior in other programs.  This is because  WAV  files
       store  the data length in the header.  However, the output driver does not know the length
       when it writes the header, and there is no value that means "length unknown".  Use the raw
       or au output driver if you need to use ogg123 in a pipe.
