NAME

   ogg123 - plays Ogg Vorbis files

SYNOPSIS

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

DESCRIPTION

   ogg123  reads  Ogg  Vorbis and FLAC 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.

OPTIONS

   --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 a file device previously specified  with
          --device.  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.

DEVICES

   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.

          matrix:value
                 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.

          verbose
                 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:

          dev:value
                 Set AIX output device to value

   alsa   Advanced Linux Sound Architecture live output driver. Options:

          buffer_time:value
                 Override   the   default   hardware   buffer   size   (in
                 milliseconds).

          dev:value
                 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
                 http://alsa.opensrc.org/ALSA+device+labels

          period_time:value
                 Override   the   default   hardware   period   size   (in
                 microseconds).

          period_time:value
                 Override   the   default   hardware   period   size   (in
                 microseconds).

          use_mmap:value
                 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:

          multi:value
                 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:

          host:value
                 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:

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

   nas    Network Audio Server live output driver. Options:

          buf_size:value
                 Set size of audio buffer on server in bytes.

          host:value
                 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:

                 server.

          sink:value
                 Specifies a non-default Pulseaudio sink for audio stream.

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

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

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

EXAMPLES

   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

INTERRUPT

   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.

FILES

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

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

BUGS

   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.
