mpg123 is a fast and versatile command-line MPEG audio player for Linux and other Unix-like operating systems. It supports various MPEG audio versions and layers, including MPEG 1.0/2.0/2.5 layers 1, 2, and 3 (MP3).
It can play audio from local files, network streams (URLs), and even from standard input. mpg123 offers a range of command-line options for controlling playback, volume, output device, and more.
It's widely used in scripting and embedded systems due to its lightweight design and robust performance. The application decodes the stream and produces a sound output via audio cards installed in the computer. mpg123 can also be used as a library to decode audio streams into raw PCM audio for other software.

Some advanced features or decoders may require optional dependencies to be installed. Output device names can be system-dependent.

mpg123 supports various output modules for different audio devices.
Use '--list-modules' to see the available modules on your system. Common examples include 'alsa', 'pulse', and 'oss'.

mpg123's return code indicates the success or failure of the playback process.
A return code of 0 typically indicates success, while non-zero values indicate errors.

During playback, you can use keyboard shortcuts to control the player.
Common shortcuts include 'space' to pause/resume, 'q' to quit, and '<' and '>' to seek backward and forward.

mpg123 was initially developed in the mid-1990s by Michael Hipp. It gained popularity as one of the first readily available and efficient MP3 decoders for Unix-like systems.
Over time, it has been actively maintained and improved by a community of developers. mpg123 has been widely used in various applications, including embedded systems, audio players, and command-line tools.
