History

edit

Development of MPlayer began in 2000. The original author,HungarianÁrpád Gereöffy, started the project because he was unable to find any satisfactory video players for Linux afterXAnimstopped development in 1999. The first version was titledmpg12play v0.1and was hacked together in half an hour usinglibmpeg3fromCinelerra-HV.Aftermpg12play v0.95pre5,the code was merged with anAVIplayer based onavifile'sWin32DLLloaderto form MPlayer v0.3 in November 2000.[7] Gereöffy was soon joined by many other programmers, in the beginning mostly fromHungary,but later worldwide.

Alex Beregszászi has maintained MPlayer since 2003 when Gereöffy left MPlayer development to begin work on a second generation MPlayer. TheMPlayer G2project was abandoned, and all the development effort was put on MPlayer 1.0.[8]

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

edit

There are variousSIP blocksthat can accelerate video decoding computation in several formats, includingPureVideo,UVD,QuickSync Video,TI Ducatiand others. Two studies in 2007 and 2010 implemented hardware decoding for MPlayer,[9]including for specific mobile device architectures.[10]

Capabilities and classification

edit

MPlayer can play a wide variety of media formats,[11]namely any format supported byFFmpeglibraries, and can also save all streamed content to a file locally.

A companion program, calledMEncoder,can take an input stream, file or a sequence of picture files, andtranscodeit into several different output formats, optionally applying various transforms along the way.

A variety ofcommand-lineparameters allows changing the appearance of the player, including-speed [number],-af scaletempofor changing audio speed while maintaining the pitch,-ss(start at ___ seconds),-sb(start at ___ bytes),-endpos(stop playing at ___ seconds),-novideofor only playing the audio track of a video, and-loop [number]for looping.[12]

Media formats

edit
MPlayer being run via command line in Microsoft Windows.

MPlayer can play many formats, including:[13]

MPlayer can also use a variety of output driver protocols to display video, includingVDPAU,theX video extension,OpenGL,DirectX,Direct3D,Quartz Compositor,VESA,Framebuffer,SDLand rarer ones such asASCII art(usingAAlibandlibcaca) andBlinkenlights.It can also be used to display TV from a TV card using the devicetv://channel,or play and capture radio channels viaradio://channel|frequency.

Since version 1.0RC1, Mplayer can decode subtitles inASS/SSAsubtitle format, usinglibass.

Available plugins

Interface and graphical front-ends

edit
Gnome-MPlayer v1.0.9 onGNOME

LikeGStreamer,MPlayer has onlycommand line interfaceand there are a couple offront-endsavailable, which useGUI widgetsofGTK,Qtor some other widget library. When not using these front-ends, mplayer can still display video in a window (with no visible controls on it), and is controlled using a keyboard.

  • GTK-based aregmplayer(official)[14][15]andGnome-MPlayer
  • Qt-based areSMPlayerandKMPlayer,among others.
  • Cocoa-based are MPlayer OS X Extended and MPlayerX[16]

Forks

edit

mplayer2was a GPLv3-licensed fork of MPlayer, largely the work of Uoti Urpala, who was excluded from the MPlayer project in May 2010 due to "long standing differences" with the MPlayer Team.[17]The main changes from MPlayer were improved pause handling, Matroska support, seeking, and support for Nvidia VDPAU; enabling multithreading by default; and the removal of MEncoder, the GUI interface, and various video drivers and bundled libraries, such as ffmpeg, relying instead on shared libraries.[18][19]The developers also indicated intentions to enable MPlayer2 to useLibavas an alternative to ffmpeg.[20]The first release, 2.0, was published in March 2011. There have been no subsequent stable releases.

mpv[21]is a GPLv2-licensed fork of mplayer2. Since June 2015, mpv has worked to relicense its code asLGPLv2.1 or above.[22]

MPlayer, MPlayer2 and mpv all use incompatibleEDLformats.[23][24][25]

edit

In January 2004, the MPlayer website was updated with an allegation that the Danish DVD player manufacturer,Kiss Technology,were marketing DVD players withfirmwarethat 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.[26]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.[26]
