VP8 is an open source video codec owned by Google and originally created by On2 Technologies to replace its predecessor VP7. The specifications are freely downloadable and Google has provided a free and irrevocable patent license promise for the format. It was announced on September 13, 2008.[1][2]

In May 2010, Google released source code for an implementation of the codec under a BSD-like open source license.[3][4]

History

On May 19, 2010, Google, which acquired On2 in 2010, released VP8 codec software under a BSD-like license and the VP8 bitstream format specification under an irrevocable free patent license[5] at its May 2010 Google I/O conference.[6] This made VP8 the second product from On2 Technologies to be open-sourced to the free software community following the 2001 release of the older VP3 codec, which was later donated (under the BSD license) to the Xiph.Org Foundation as the Theora codec; the most vocal urging for Google to release the VP8 source code came from the Free Software Foundation, which issued a March 12, 2010, open letter requesting Google to gradually replace the usage of the Adobe Flash Player and H.264 on YouTube with a mixture of HTML5 and an open-sourced VP8.[7]

On May 19, 2010, the WebM Project was launched, featuring contributions from "Mozilla,[8] Opera,[9][10] Google[11] and more than forty other publishers, software and hardware vendors" in a major effort to use VP8 as the codec for HTML5.[12] In the WebM container format, the VP8 video is used with Vorbis audio.[13][14] Internet Explorer 9 will support VP8 video playback if the proper codec is installed.[15]
