'''MPlayer''' is a [[free and open-source]] [[media player software]] application. It is available for [[Linux]], [[OS X]] and [[Microsoft Windows]]. Versions for [[OS/2]], [[Syllable Desktop|Syllable]], [[AmigaOS]], [[MorphOS]] and [[AROS Research Operating System]] are also available. A port for [[DOS]] using [[DJGPP]] is also available.<ref>{{cite web |url=http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/util/user/mplayer/ |title=Index of /pub/micro/pc-stuff/freedos/files/util/user/mplayer |publisher=Ibiblio.org |access-date=2012-01-01}}</ref> Versions for the [[Wii]] [[Homebrew Channel]]<ref>{{cite web |author=Erant |url=http://hackmii.com/2008/08/libdi-and-the-dvdx-installer/ |title=libdi and the DVDX installer |publisher=Hackmii.com |access-date=2012-01-01}}</ref> and Amazon Kindle<ref>{{cite web |url=http://gitorious.org/kindlebrew |title=kindlebrew |publisher=Gitorious |access-date=2012-01-01 |url-status=dead |archive-url=https://web.archive.org/web/20120407063924/http://gitorious.org/kindlebrew |archive-date=2012-04-07 }}</ref> have also been developed.

==History==
Development of MPlayer began in 2000. The original author, [[Hungary|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 half an hour using ''libmpeg3'' from [[Cinelerra|Cinelerra-HV]]. After ''mpg12play v0.95pre5'', the code was merged with an [[Audio Video Interleave|AVI]] player based on ''avifile''{{'}}s ''[[Win32]] [[Dynamic-link library|DLL]] loader'' to form MPlayer v0.3 in November 2000.<ref>[http://www.mplayerhq.hu/design7/history.html History]</ref> 
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 was abandoned, and all the development effort was put on MPlayer 1.0.<ref>{{cite web |title=MPlayer - The Movie Player |url=http://mplayerhq.hu/design7/news.html |access-date=2012-06-24}}</ref>

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 [[Semiconductor intellectual property core|SIP blocks]] that can accelerate video decoding computation in several formats, including [[Nvidia PureVideo|PureVideo]], [[Unified Video Decoder|UVD]], [[Intel Quick Sync Video|QuickSync Video]], [[OMAP 4|TI Ducati]] and others. Two studies in 2007 and 2010 implemented  hardware decoding for MPlayer,<ref name=zhang>{{Cite conference |date=2010 |title=The design and implementation of an embedded high definition player |conference=The 2nd International Conference on Computer and Automation Engineering (ICCAE) |volume=4 |vauthors=Zhang H etal}}</ref> including for specific mobile device architectures.<ref>{{Cite book |last1=Chang |first1=Hoseok |last2=Lee |first2=Youngjoon |last3=Sung |first3=Wonyong |chapter=Performance Optimization of a Multimedia Player on a Mobile CPU Platform |date=October 2007 |title=2007 IEEE Workshop on Signal Processing Systems |chapter-url=http://dx.doi.org/10.1109/sips.2007.4387538 |pages=163–168 |publisher=IEEE |doi=10.1109/sips.2007.4387538|isbn=978-1-4244-1221-1 |s2cid=8023880 }}</ref>

==Capabilities and classification==
MPlayer can play a wide variety of media formats,<ref>{{cite web |url=http://www.mplayerhq.hu/DOCS/codecs-status.html |title=Codec Status Table |publisher=Mplayerhq.hu |access-date=2012-01-01}}</ref> 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, file or a sequence of picture files, and [[transcoding|transcode]] it into several different output formats, optionally applying various transforms along the way.

A variety of [[command-line interface|command-line]] parameters allows changing the appearance of the player, including <code>-speed [number]</code>, <code>-af scaletempo</code> for changing audio speed while maintaining the pitch, <code>-ss</code> (start at ___ seconds), <code>-sb</code> (start at ___ bytes), <code>-endpos</code> (stop playing at ___ seconds), <code>-novideo</code> for only playing the audio track of a video, and <code>-loop [number]</code> for looping.<ref>MPlayer documentation and user manual</ref>

==Media formats==
[[File:MPlayer cmd win32.png|thumb|MPlayer being run via command line in Microsoft Windows.]]

===Available plugins===
* [[XMMS]] plugins
* [[Avisynth]]

== {{Anchor|GNOME MPlayer|gMplayer|}}Interface and graphical front-ends==
[[File:Gnome-MPlayer v1.0.9 on Debian 8.png|thumb|Gnome-MPlayer v1.0.9 on [[GNOME]]]]

Like [[GStreamer]], MPlayer has only [[command line interface]] and there are a couple of [[Front-end (computing)|front-end]]s available, which use [[GUI widget]]s of [[GTK]], [[Qt (software)|Qt]] or 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 are '''gmplayer''' (official)<ref>{{cite web|url=http://www.mplayerhq.hu/DOCS/README|title=README|access-date=2016-03-19}}</ref><ref>{{cite web|url=http://www.mplayerhq.hu/DOCS/HTML/en/gui.html|title=What about the GUI?|access-date=2016-03-19}}</ref> and '''Gnome-MPlayer'''
* [[Qt (software)|Qt]]-based are [[SMPlayer]] and <abbr title="Konqueror Media Player">KMPlayer</abbr>, among others.
* [[Cocoa (API)|Cocoa]]-based are MPlayer OS X Extended and MPlayerX<ref>{{cite web |url=http://www.mplayerosx.ch/ |title=MPlayer OSX Extended |date= 2011-12-09 |access-date= 2015-01-23 }}</ref>

==Forks==
'''mplayer2''' was 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.<ref>{{cite web |url=https://www.phoronix.com/scan.php?page=news_item&px=OTI0Ng |title=Is MPlayer2 a viable fork of MPlayer? |publisher=[[Phoronix]] |date=2011-03-24 |access-date=2014-04-18}}</ref> 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.<ref>{{cite web|url=http://www.mplayer2.org/comparison.html |title=mplayer2 differences from mplayer |date=2011 |access-date=May 4, 2015 |url-status=dead |archive-url=https://web.archive.org/web/20120504055423/http://www.mplayer2.org/comparison.html |archive-date=May 4, 2012 }}</ref><ref>{{cite web |url=http://ostatic.com/blog/did-you-know-there-was-a-fork-of-mplayer |title=Did You Know there was a Fork of MPlayer? |publisher=ostatic.com |date=2011-03-22 |access-date=2011-11-29 |archive-date=2012-01-11 |archive-url=https://web.archive.org/web/20120111135451/http://ostatic.com/blog/did-you-know-there-was-a-fork-of-mplayer |url-status=dead }}</ref> The developers also indicated intentions to enable MPlayer2 to use [[Libav]] as an alternative to ffmpeg.<ref>{{cite web|url=https://blogs.gentoo.org/scarabeus/2013/01/15/libav-going-to-be-default-provider-for-your-codec-experience/#comment-2705|title=Libav going to be default provider for your codec experience (comment)|date=January 16, 2013}}</ref> The first release, 2.0, was published in March 2011. There have been no subsequent stable releases.

'''[[mpv (media player)|mpv]]'''<ref>{{cite web|url=http://mpv.io|title=mpv.io|access-date=2015-01-28}}</ref> is a GPLv2-licensed fork of mplayer2. Since June 2015, mpv has worked to relicense its code as [[GNU Lesser General Public License|LGPL]] v2.1 or above.<ref>{{cite web|url=https://github.com/mpv-player/mpv/issues/2033|title=Possible LGPL relicensing|website=[[GitHub]]|access-date=2016-09-27}}</ref>

MPlayer, MPlayer2 and mpv all use incompatible [[Edit decision list|EDL]] formats.<ref>{{cite web|url=https://www.mplayerhq.hu/DOCS/HTML/en/edl.html|title=3.7.

==Legal controversy==
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.<ref name="2004-03">{{cite web |title=MPlayer - The Movie Player |date=2004-01-10 |url=http://mplayerhq.hu/design7/news-archive.html#kiss05 |access-date=2012-06-24}}</ref> 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.<ref name="2004-03" />
