Support for VDPAU accelerated AV1 decoding was added with libvdpau-1.5. Support for the same in ffmpeg is added with this patch. Profiles related to VDPAU AV1 can be found in latest vdpau.h present in libvdpau-1.5. Add AV1 VDPAU to list of hwaccels and supported formats Added file vdpau_av1.c and Modified configure to add VDPAU AV1 support. Mapped AV1 profiles to VDPAU AV1 profiles. Populated the codec specific params that need to be passed to VDPAU. Signed-off-by: Philip Langdale <philipl@overt.org>
