			Support for VDPAU accelerated VP9 decoding was added with libvdpau-1.3. Support for the same in ffmpeg is added with this patch. Profiles related to VDPAU VP9 can be found in latest vdpau.h present in libvdpau-1.3. DRC clips are not supported yet due to http://trac.ffmpeg.org/ticket/8068 Add VP9 VDPAU to list of hwaccels and supported formats Added file vdpau_vp9.c and Modified configure to add VDPAU VP9 support. Mapped VP9 profiles to VDPAU VP9 profiles. Populated the codec specific params that need to be passed to VDPAU. Signed-off-by: Philip Langdale <philipl@overt.org>
