Shortly before announcing its decision to remove H.264 support for HTML5 video from Chrome, Google's codec developers submitted an I-D of its VP8 Data Format and Decoding Guide to the IETF with a request for comments. The document provides a detailed description of the bitstream format and the decoding mechanism used for the VP8 video codec. Google took over the codec-lab just under a year ago and released the codec under an open source license as part of its WebM shortly thereafter.
