MPlayer is a free software and open source media player. The program is available for all major operating systems, including Linux, Mac OS X and other Unix-like systems, as well as for Microsoft Windows. Versions for OS/2, Syllable, AmigaOS, MorphOS and AROS Research Operating System are also available. A port for DOS using DJGPP is also available. Versions for the Wii Homebrew Channel and Amazon Kindle have also been developed.

History

Development of MPlayer began in 2000. The original author, Hungarian Árpád Gereöffy, started the project because he was unable to find any satisfactory video players for Linux after XAnim stopped development in 1999. The first version was titled mpg12play v0.1 and was hacked together in a half hour using libmpeg3 from www.heroinewarrior.com. After mpg12play v0.95pre5, the code was merged with an AVI player based on avifile's Win32 DLL loader to form MPlayer v0.3 in November 2000. Gereöffy was soon joined by many other programmers, in the beginning mostly from Hungary, but later worldwide.

Alex Beregszászi has maintained MPlayer since 2003 when Gereöffy left MPlayer development to begin work on a second generation MPlayer. The MPlayer G2 project is currently abandoned, and all the development effort is put on MPlayer 1.0.

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 became commonly used on other operating systems.

Video acceleration

There are various SIP blocks that can do the computations to decode video in certain formats, such as PureVideo, UVD, QuickSync Video, TI Ducati and more. Such needs to be supported by the device driver, which in turn provides one or multiple interfaces, like e.g. VDPAU, VAAPI, Distributed Codec Engine or DXVA to end-user software like MPlayer to access this hardware and offload computation to it.

Capabilities and classification

MPlayer can play a wide variety of media formats, namely any format supported by FFmpeg libraries, and can also save all streamed content to a file locally.

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

Media formats

MPlayer being run via command line in Microsoft Windows.

MPlayer can play many formats, including:

• Physical media: CDs, DVDs, Video CDs, Blu-ray discs
• Container formats: 3GP, AVI, ASF, FLV, Matroska, MOV (QuickTime), MP4, NUT, Ogg, OGM, RealMedia, Bink
• Video formats: Cinepak, DV, H.263, H.264/MPEG-4 AVC, HuffYUV, Indeo, MJPEG, MPEG-1, MPEG-2, MPEG-4 Part 2, RealVideo, Sorenson, Theora, WMV, Bink
• Audio formats: AAC, AC3, ALAC, AMR, DTS, FLAC, Intel Music Coder, Monkey's Audio, MP3, Musepack, RealAudio, Shorten, Speex, Vorbis, WMA, Bink
• Subtitle formats: AQTitle, ASS/SSA, CC, JACOsub, MicroDVD, MPsub, OGM, PJS, RT, Sami, SRT, SubViewer, VOBsub, VPlayer
• Image formats: BMP, JPEG, MNG, PCX, PTX, TGA, TIFF, SGI, Sun Raster
• Protocols: RTP, RTSP, HTTP, FTP, MMS, Netstream (mpst://), SMB, ffmpeg:// (Uses FFmpeg's protocol implementations)

MPlayer can also use a variety of output driver protocols to display video, including VDPAU, the X video extension, OpenGL, DirectX, Direct3D, Quartz Compositor, VESA, Framebuffer, SDL and rarer ones such as ASCII art (using AAlib and libcaca) and Blinkenlights. It can also be used to display TV from a TV card using the device tv://channel, or play and capture radio channels via radio://channel|frequency.

Since version 1.0RC1, Mplayer can decode subtitles in ASS/SSA subtitle format, using libass.

Available plugins

• XMMS plugins
• Avisynth

Graphical front-ends

Like GStreamer, MPlayer is a command-line application and there are a couple of front-ends available, which use GUI widgets of GTK+, Qt or some other widget library.

• GTK+-based are gMplayer and Gnome MPlayer
• Qt-based are SMPlayer, ExMplayer and KMPlayer
• Cocoa-based are MPlayer OS X Extended and MPlayerX

Forks

mplayer2 is a GPLv3-licensed fork of MPlayer, largely the work of Uoti Urpala, who has been ejected from the MPlayer project on May 30, 2010 due to "long standing differences" with the MPlayer Team.

The main changes from MPlayer were improved pause handling, Matroska support, seeking, and support for Nvidia VDPAU; enabling multithreading by default; using gettext for translations; and the removal of MEncoder, the GUI interface, and various video drivers and bundled libraries, such as ffmpeg, relying instead on shared libraries. The developers also indicated intentions to enable MPlayer2 to use libav as an alternative to ffmpeg.

The first release, 2.0, was published in March 2011. There have been no subsequent stable releases.

mpv is a GPLv2-licensed fork of mplayer2 and effectively its successor.

MPlayer, MPlayer2 and mpv all use incompatible EDL formats.

Legal issues

In January 2004, the MPlayer website was updated with an allegation that the Danish DVD player manufacturer, KISS Technology, were marketing DVD players with firmware that included parts of MPlayer's GPL-licensed code. The implication was that KISS was violating the GPL, since KISS did not release its firmware under the GPL license. The response from the managing director of KISS, Peter Wilmar Christensen, countered that the similarities between the two pieces of code indicate that the MPlayer team had in fact used code from KISS's firmware. However, the KISS DVD player, released in 2003, used a subtitle file format that is specific to MPlayer, which was designed by an MPlayer developer in 2001.
