ogg123 − plays Ogg Vorbis files
ogg123 [ -vqzVh ] [ -k seconds ] [ -b buffer_size ] [ -d driver [ -o option:value ] [ -f filename ] ] file ... | 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.
-b n, --buffer n
Use a buffer of approximately ’n’ kilobytes.
-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
-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.
-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. | ||
|
alsa |
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. Note that this driver has not been tested! | ||
|
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 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.
The use of /etc/ogg123rc and ~/.ogg123rc has been removed in favor of the configuration system provided by libao. The ability to override libao will be added in a future version.
/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.
