VP8 is an open video compression format owned by Google and originally created by On2 Technologies to replace its predecessor VP7.

It was announced on September 13, 2008.[8][9] On May 19, 2010,[1][2] Google released technology IP rights for the VP8 format under irrevocable patent promise and for the specification text a Creative Commons license.[10] Google also released source code for libvpx - a VP8 codec reference implementation under a BSD-like license, later changed to a BSD license plus an additional patent grant.[6][7][11] There is contention over whether the old license for VP8 was in fact an open-source license.[12][13][14][15]

History

On May 19, 2010, Google, which acquired On2 in 2010,[16] released VP8 codec software under a BSD-like license and the VP8 bitstream format specification under an irrevocable free patent license[17] at its May 2010 Google I/O conference.[18] 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 an open letter on March 12, 2010 asking 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.[19]

On May 19, 2010, the WebM Project was launched, featuring contributions from "Mozilla,[20] Opera,[21][22] Google[23] and more than forty other publishers, software and hardware vendors" in a major effort to use VP8 as the codec for HTML5.[24] In the WebM container format, the VP8 video is used with Vorbis audio.[25][26] Internet Explorer 9 will support VP8 video playback if the proper codec is installed.[27] Android is also officially planned to be WebM-enabled in the 4th quarter of 2010.[28]
