OGG Theora

Theora is a free video compression format derived from the proprietary VP3 codec, released into the public domain by On2 Technologies.

It is broadly comparable in design and bitrate efficiency to MPEG-4 Part 2, early versions of Windows Media Video, and RealVideo while lacking some of the features present in some of these other codecs. It is comparable in open standards philosophy to the BBC's Dirac codec.
