Matroska (MKV) is not a codec (like are MPEG-1, XviD, DivX, or VP3) but a container as well as the MPEG4 ( .mp4 ), QuickTime ( .mov ) or the Audio Video Interleave ( .avi ). The difference with this last is that the MKV can gather within the same file (generally with the extension .mkv ) several video and audio tracks as well as subtitles and chapters (just like QuickTime), the whole for a size of file equivalent to traditional the DivX. In comparison, the AVI is limited to only one video track and to 99 audio tracks, with limitations as for the possible codecs. The audio codecs supported by Matroska include Ogg Vorbis, AAC, MP3, and AC3. The supported video codecs include DivX, XviD, RV10, H.264 and Theora. The formats of supported subtitles include SubRip (srt) and SubStationAlpha (ssa). This container thus allows the use of the most powerful codecs such as the H.264 and AAC.
The purpose of Matroska is to become the standard formats multimedia. It is derived from project MCF, but remotely appreciably because it uses EBML (Extensible Binary Meta Language), a binary format derived from XML. EBML makes it possible the development team of Matroska to obtain an important advantage with regard to the future extensions of the format, without to be incompatible with the former parseurs.
OriginMatroska comes from the Russian word matriochka (Russian headstock) which corresponds well to the definition of the matroska: it is a video container which makes it possible to mix several audio tracks and subtitles with a video track.
