MPlayer is a free and open source media player distributed under the GNU General Public License. The program is available for all major operating systems, including Linux and other Unix-like systems, Microsoft Windows and Mac OS X.

MPlayer is known to support more multimedia formats than any other player^{[citation needed]}. In addition to its wide range of supported formats MPlayer can also save all streamed content to a file.

A companion program, MEncoder, can take an input stream or file and transcode it into several different output formats, optionally applying various transforms along the way.

MPlayer is a command line application which has different optional GUIs for each of its supported operating systems. Commonly used GUIs are GMPlayer (an X Window System GUI for GNU/Linux and other Unix-like systems), MPlayer OS X (for Mac OS X), MPUI (for Windows) and WinMPLauncher (also for Windows). Several alternative GUI frontends are also available for each platform.

[edit] Development

Development of MPlayer began in 2000. The original author, Árpád Gereöffy (known as A'rpi / Astral in the demoscene), was soon joined by many other programmers. In the beginning most developers were from Hungary, but nowadays the developers come from all over the world. Alex Beregszászi has maintained MPlayer since 2003 when Árpád Gereöffy left MPlayer development to begin work on a second generation MPlayer. The MPlayer G2 project is currently paused for a number of reasons. ^{[citation needed]}

MPlayer was previously called "MPlayer - The Movie Player for Linux" by its developers but this was later shortened to "MPlayer - The Movie Player" after it was made available for multiple operating systems.

[edit] Legal issues

Most video and audio codecs are supported natively through the libavcodec library of the FFmpeg project. For those codecs where no open source decoder has been implemented yet MPlayer relies on binary codecs. On x86 platforms it can use Windows DLLs directly with the help of a DLL loader forked from avifile (which itself forked its loader from the Wine project).

The combination of CSS decryption software and implementation of codecs covered by software patents places a fully-functional MPlayer in the legal bind shared by most open source multimedia players. In the past MPlayer used to include OpenDivX, a GPL-incompatible decoder library. This has since been removed, making MPlayer itself completely free software.
