       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

       -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

                     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

                     Override the default hardware period size (in

                     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
                     "whizbang.com:555".  (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

       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 overhead.

       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

                     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.

                     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.

                     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

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

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

       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.
