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 intentionally 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. This series is based upon the following series: * media: cedrus: Add H264 decoding support Changes since v2: * Moved headers to non-public API; * Added H265 capability for A64 and H5; * Moved docs to ext-ctrls-codec.rst; * Mentionned sections of the spec in the docs; * Added padding to control structures for 32-bit alignment; * Made write function use void/size in bytes; * Reduced the number of arguments to helpers when possible; * Removed PHYS_OFFSET since we already set PFN_OFFSET; * Added comments where suggested; * Moved to timestamp for references instead of index; * Fixed some style issues reported by checkpatch. Changes since v1: * Added a H.265 capability to whitelist relevant platforms; * Switched over to tags instead of buffer indices in the DPB * Declared variable in their reduced scope as suggested; * Added the H.265/HEVC spec to the biblio; * Used in-doc references to the spec and the required APIs; * Removed debugging leftovers.
