mpg321 --- Free clone of mpg123, a command-line mp3 player
mpg321 [options] file(s) | URL(s) | -
mpg321 is a free command-line mp3 player,
which uses the mad audio decoding library. mpg321 is written to be a
drop-in replacement for the non-free mpg123 player.
Some functions remain unimplemented, but mpg321 should function as a
basic drop-in replacement for mpg123 front-ends such as
gqmpeg, and those programs which use mpg123 to decode
mp3 files (like gtoaster, and other CD-recording
mpg321 differs from mpg123 in several ways. First and foremost, it is fully Free, under the GNU General
Public License. Secondly, it allows run-time switching of output devices
(via the -o switch). (mpg321 also allows configuring
a default output device at compile-time, but run-time switching is always
Set the output device type to devicetype.
devicetype can be one of:
oss - the Linux Open Sound System;
sun - the Sun audio system;
alsa - the Advanced Linux Sound Architecture;
alsa09 - the Advanced Linux Sound Architecture, version 0.9;
esd - the Enlightened Sound Daemon;
arts - the analog real-time synthesiser
See -a device, below.
-a device, --audiodevice device
Use device for audio-out instead of the default device,
depending on the output device you've chosen (via -o devicetype).
By default this is the native sound device.
Generally this is the device for devicetype
(or the default system device) to use for output (i.e. /dev/sound/dsp1).
This option has no effect with -o arts.
For -o esd, specify the host on which esd is running; defaults to localhost.
For -o alsa, specify card:device; defaults to 0:0.
-g N, --gain N
Set gain (volume) to N (1-100).
-k N, --skip N
Skip N frames into the file being played.
-n N, --frames N
Decode only the first N frames of the stream. By default, the entire stream is decoded.
-@ list, --list list
Use the file list for a playlist. The list should be in a format of filenames followed by a line feed. Multiple -@ or --list specifiers will be ignored; only the last -@ or --list option will be used. The playlist is concatenated with filenames specified on the command-line to produce one master playlist. A filename of '-' will cause standard input to be read as a playlist.
Shuffle playlists and files specified on the command-line. Produces a randomly-sorted playlist which is then played through once.
Randomise playlists and files specified on the command-line. Files are played through, choosing at random; this means that random files will be played for as long as mpg321 is running.
Be more verbose. Show current byte, bytes remaining, time, and time remaining, as well as more information about the mp3 file.
Use standard output instead of an audio device for output. Output is in 16-bit PCM, little-endian.
-w N, --wav N
Write to wav file N instead of using the audio device. This option will be preferred if --cdr or --au are specified too. Specifying '-' for N will cause the file to be written to standard output.
Write to cdr file N instead of using the audio device. Specifying '-' for N will cause the file to be written to standard output.
Write to au file N instead of using the audio device. Specifying '-' for N will cause the file to be written to standard output.
Test mode; do no output at all.
Quiet mode; suppress output of mpg123 boilerplate and file and song name.
"Remote control" mode. Useful for front-ends. Allows seeking and pausing of mp3 files. See README.remote (in /usr/share/doc/mpg321 on Debian and some other systems.)
Force stereo output: duplicates mono stream on second output channel. Useful for output for devices that don't understand mono, such as some CD players.
Aggressive mode; try to get higher priority on the system. Needs root permissions.
Skip N frames between printing a frame status update, in both Remote Control (-R) and verbose (-v) mode. Can help CPU utilisation on slower machines. This is an mpg321-specific option.
