Patch to support VP9 encoding with new profiles 1-3. Profile 1 (8-bit 422/444) should work with default libvpx configuration. However you will need to configure libvpx with --enable-vp9-highbitdepth before building and linking with ffmpeg for profile 2 (10-/12-bit 420) and profile 3 (10-/12-bit 422/444) encoding. You may use the appropriate profile option on the command line: -profile:v 1 for 422/444 8-bit encoding -profile:v 2 for 420 10-/12- bit encoding -profile:v 3 for 422/444 10-/12-bit encoding If you do not use the -profile:v option, it will be deduced from the source format.
