MPlayer supports a wide variety of media formats. 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. MEncoder is a free command line video decoding encoding and filtering tool released under the GNU General Public License. See also Lossy data conversion Transcoding is the direct digital-to-digital conversion of one encoding to another

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

Development

Development of MPlayer began in 2000. 2000 ( MM) was a Leap year that started on Saturday of the Common Era, in accordance with the Gregorian calendar. The original author, Árpád Gereöffy (known as A'rpi / Astral in the demoscene), was soon joined by many other programmers. The demoscene is a Computer art Subculture that specializes in producing demos, which are non-interactive audio-visual presentations that run in The project was started because A'rpi was unable to find any satisfactory video players for Linux. The first version was titled mpg12play v0. 1 and was hacked together in a half hour using libmpeg3 from http://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. The Windows API, informally WinAPI, is Microsoft's core set of Application programming interfaces (APIs available in the Microsoft Windows Operating 3 in November 2000 [1]. In the beginning most developers were from Hungary, but currently the developers are located worldwide. Hungary (Magyarország 'mɔɟɔrorsaːg) officially in English the Republic of Hungary ( Magyar Köztársaság, literally Magyar (Hungarian Republic Alex Beregszászi has maintained MPlayer since 2003 when Árpád Gereöffy left MPlayer development to begin work on a second generation MPlayer. Year 2003 ( MMIII) was a Common year starting on Wednesday of the Gregorian calendar. The MPlayer G2 project is currently paused for a number of reasons. [2]

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 multiple operating systems.

Legal issues

Most video and audio formats are supported natively through the libavcodec library of the FFmpeg project. libavcodec is a Free software / Open source LGPL -licensed library of Codecs for encoding and decoding video and audio data it is written in the In Computer science, a library is a collection of Subroutines used to develop Software. FFmpeg is a computer program that can record convert and stream digital audio and Video in numerous formats For those formats where no open source decoder has been implemented yet MPlayer relies on binary codecs. 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). In Software engineering, a project fork happens when developers take a copy of Source code from one software package and start independent development Wine is a free Software application which aims to allow Unix-like computer Operating systems on the X86 architecture to execute

The combination of CSS decryption software and implementation of formats covered by software patents places a fully-functional MPlayer in the legal bind shared by most open source multimedia players. Content Scramble System ( CSS) is a Digital Rights Management (DRM scheme used on almost all commercially produced DVD -Video discs Software patent does not have a universally accepted definition In the past MPlayer used to include OpenDivX, a GPL-incompatible decoder library. Xvid (formerly " XviD " is a Video codec library following the MPEG-4 standard This has since been removed, making MPlayer itself completely free software. Free software or software libre is Software that can be used studied and modified without restriction and which can be copied and redistributed in modified or unmodified Usage of patented codecs in free software however is a still pending potential problem affecting FFmpeg, MPlayer and similar software when used in countries where software patents apply. FFmpeg is a computer program that can record convert and stream digital audio and Video in numerous formats
