This introduces the required bits for supporting HEVC/H.265 both in the V4L2 framework and the Cedrus VPU driver that concerns Allwinner devices. A specific pixel format is introduced for the HEVC slice format and controls are provided to pass the bitstream metadata to the decoder. Some bitstream extensions are knowingly not supported at this point. Since this is the first proposal for stateless HEVC/H.265 support in V4L2, reviews and comments about the controls definitions are particularly welcome. On the Cedrus side, the H.265 implementation covers frame pictures with both uni-directional and bi-direction prediction modes (P/B slices). Field pictures (interleaved), scaling lists and 10-bit output are not supported at this point.
