On2 TrueMotion VP6 is aproprietarylossyvideo compression format andvideo codec. It is an incarnation of theTrueMotion video codec, a series of video codecs developed byOn2 Technologies. This codec is commonly used byAdobe Flash,Flash Video, andJavaFX media files.
The VP6 codec was introduced in May 2003.[1] In October 2003, On2 officially released its TrueMotion VP6 codec.[2]
In November 2003, On2 announced that VP6 had been chosen as a codec for China'sEnhanced Versatile Disc (EVD), a competitor format toDVD.Beijing-based company E-World was to be the exclusive reseller of the EVD VP6 technology inChina, with On2 Technologies earning royalty payments of about $2 USD per player. Then in April 2004 On2 announced that negotiations with E-World had broken down and that On2 would file multiple breach of contract claims against E-World in arbitration proceedings. In March 2005, On2 announced that the arbitrator had dismissed all of On2's claims and had decided that E-World owed nothing to On2. Although E-World included VP6 to its EVD standardization proposal to the Chinese government, it is not clear what, if any, action was then taken by the government. The EVD format initiative appears to be indefinitely stalled.[3]
In November 2003, On2 announced that the VP6 codec will be used in products for broadcasting in the field, such as withBBC reporters andQuickLink software.[4][5]
In January 2005, On2 announced a newVP7 codec with better compression capabilities than VP6.[6]
In April 2005, On2 Technologies licensed On2 Video Codec (including VP6 and VP7) forMacromedia Flash.[7] In August 2005,Macromedia announced they had selected VP6 as the flagship new codec for video playback in the newFlash Player 8.[8][9]
In March 2006, a VP6 decoder (libvp62) appeared as anopen-source project, but was driven underground by On2 on copyright infringement claims.[10][11]
As of September 2006, an open-source implementation of the decoder is part of thelibavcodec project. VP6 decoder is part of stable versionFFmpeg 0.5, released in March 2009.[12] There are some claims that producing or dealing with VP6 video streams inside libavcodec/libavformat is discouraged and/or refused due to clashes between the FFmpeg's developers and On2 technologies by a claim of Intellectual Property and Trade Secrets Infringement made by the corporation itself.[citation needed]
In May 2008,Sun Microsystems announced it had licensed On2 TrueMotion codecs to add video capabilities to JavaFX, a family of products for creating Rich Internet Applications (RIAs) across Mobile, Desktop, TV and more.[13] JavaFX uses On2 VP6.[14]
Later incarnations of this codec areVP7,VP8 andVP9. With the Google acquisition of On2, VP8 is licensed as open source. Earlier versions such as VP6 remain unsupported.
