LEAD MKV Media Source

LEAD's MKV Media Source can be used to play files based on the open source Matroska (MKV) File Format.

WebM is a new multimedia  format sponsored by Google, among other companies, for use with HTML5 video. The WebM format was developed with the goal of creating a completely open and free multimedia streaming format designed for use over the internet. WebM is encapsulated as a Matroska file using a VP8 codec for video and a Vorbis codec for audio..Both VP8 and Vorbis are based on free and open standards and by using the WebM format, developers can possibly eliminate the potential third party patent issues associated with some of the other streaming technologies, such as H.264 and  MPEG4.

MKV files are very popular as file exchange formats for large (over 4GB) video files. The LEAD MKV Media Source does not support every video and audio compression. The following compressions are supported:
