LEAD MKV Demultiplexer

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

The MKV file format has several advantages over other formats:

• It can handle large (over 4 GB) video files.
• It supports subtitles.
• It is free from the potential third party patent issues associated with some streaming technologies, such as H.264 and MPEG4.

WebM is a 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.

MKV files are very popular for large (over 4GB) video files. LEAD's MKV Multiplexer does not support every audio compression. It does, however, support every video compression whose media type is indicated by a FOURCC value, just like the AVI format. The following compressions are supported:
