* lavc/hevc_ps: Add SPS/PPS parse support for HEVC extension syntaxLinjie Fu2023-02-27
| | | | | | | | | | | | 1. Add extension syntax according to 7.3.2.2.3/7.3.2.3.3 in T-REC-H.265-201911. 2. Keep using parsed PPS when bitstream overread for compatibility. For example, the clip PS_A_VIDYO_3.bit in FATE test has incomplete extension syntax which will be overread and un-decodable if without this change. 3. Format brace in pps_range_extensions().

| | | | | | | | | Parse all the constraint flags according to ITU-T Rec. H.265 (02/2018). They have to be passed to hw decoders to determine the exact profile for Range Extension HEVC. Signed-off-by: Linjie Fu <linjie.fu@intel.com>

* avcodec/hevc_ps: Expose all SPS and PPS range extension flagsPhilip Langdale2019-02-16
| | | | | | | We need all the flags to be exposed to be able to pass them on to HW decoders. I did not attempt to nuance any of the warnings about flags being unsupported as there's no way, at the point we extract flags, to say whether an HW decoder is being used.

* hevc: Improve stream constraint values in common headerMark Thompson2017-10-17
| | | | | | | | | | Add comments to describe the sources of the constraint values expressed here, and add some more related values which will be used in following patches. Fix the incorrect values for SPS and PPS count (they are not the same as those used for H.264), and remove HEVC_MAX_CU_SIZE because it is not used anywhere. (cherry picked from commit b88da98b34809dedf8882d43ed543632ed233538)

* hevcdec: move parameter set parsing into a separate headerAnton Khirnov2016-10-16
This code is independent from the decoder, so it makes more sense for it to to have its own header.
