VP8
From MobileRead
VP8 is an open video compression format released by Google, originally created by On2 Technologies.
[edit] Implementation
Google's libvpx is currently the only encoder and main decoder for this format. The WebM Project was launched in a major effort to use VP8 as the video format for HTML5. In the WebM container format, the VP8 video is used with Vorbis audio.
[edit] History
VP8 is derived from VP7 which itself comes from VP6 (Used in FLV), VP5 and earlier VP3 used in Theora.
