Matroska aims to become THE standard
of multimedia container formats. It was derived from a project called MCF, but
differentiates from it significantly because it is based on EBML (Extensible
Binary Meta Language), a binary derivative of XML. EBML enables the Matroska
Development Team to gain significant advantages in terms of future format extensibility,
without breaking file support in old parsers.
It is intended to serve as a universal format for storing common multimedia
content, like movies or TV shows. Matroska is similar in conception to other
containers like AVI, MP4 or ASF, but is completely open source. Matroska file
types are .MKV for video (and audio) and .MKA for audio-only files.
To encode MKV video, please have CCCP
