*[Forking the thread]*
*
*
*Hello folks,*

Google confirms that the VP8 patent grant applies to both third-party
hardware and software implementations of VP8.
*
*
*Google encourages the community to create hardware implementations of VP8,
and has recently blogged about a number of new hardware implementations on
the WebM blog (
http://blog.webmproject.org/2012/03/webm-gaining-momentum-in-hardware.html).
*
*
*
*Google is quite proud of what the community has done with VP8 and looks
forward to seeing more implementations of VP8 in both hardware and
software. *
*
*
*Regards,*
*
*
*/Serge Lachapelle, Google, Stockholm*
