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.
- -p n, --prebuffer n
- Prebuffer
’n’ percent of the input buffer. Playback won’t begin until this prebuffer
is complete.
- -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
- Assigns
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.
- -z, --shuffle
- Play files in
pseudo-random order.
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.
- 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.
Options:
- dsp
- DSP device for soundcard. Defaults to /dev/dsp.
- sun
- Sun Audio driver for NetBSD, OpenBSD, and Solaris.
Options:
- dev
- Audio
device for soundcard. Defaults to /dev/audio.
- alsa09
- Advanced Linux Sound
Architecture.
Options:
- card
- Sound card number. (Default = 0)
- dev
- Device number
on the sound card. (Default = 0)
- buf_size
- Override the default buffer size
(in bytes).
- irix
- IRIX audio driver.
- arts
- aRts Sound Daemon.
- esd
- Enlightened
Sound Daemon.
Options:
- host
- The hostname where esd is running. This can include
a port number after a colon, as in "whizbang.com:555". (Default = localhost)
- 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.
- raw
- Raw sample output. Writes raw audio samples
to a file.
Options:
- byteorder
- Choose big endian, little endian, or native
byte order. (Default = "native")
- 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.
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.
- /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.
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.
