* lavc/hevc_ps: compactify ShortTermRPSAnton Khirnov2024-05-311-3/+3
| | | | | | Do not use larger fields than needed, use size-1 bitfields for flags. Reduces sizeof(HEVCSPS) by 1280 bytes.
* lavc/hevc_ps: reduce the size of ShortTermRPS.usedAnton Khirnov2024-05-311-14/+19
| | | | | | | It is currently an array of 32 uint8_t, each storing a single flag. A single uint32_t is sufficient. Reduces sizeof(HEVCSPS) by 1792 bytes.
* lavc/hevc_ps: do not store delta_poc_s[01] in ShortTermRPSAnton Khirnov2024-05-311-2/+2
| | | | | | | | | They are only used in vulkan_hevc and are not actually needed, as they can be computed from delta_poc. Reduces sizeof(HEVCSPS) by 16kB. Also, fix a typo (s0->s1) in the code being touched.
* lavc/hevc_ps: fix variable signedness in ff_hevc_decode_short_term_rps()Anton Khirnov2024-05-311-2/+4
| | | | | | It is actually supposed to go negative in the loop over num_negative pics, but underflow does not break anything as the result is then assigned to a signed int.
* lavc/hevc_ps/HEVCSPS: change flags into uint8_tAnton Khirnov2024-05-311-48/+47
| | | | | | | Reduces sizeof(HEVCSPS) by 64 bytes. Also improve flag names: drop redundant suffixes and prefixes, and consistently use disabled/enabled.
* lavc/hevc_ps: reduce the size of used_by_curr_pic_lt_sps_flagAnton Khirnov2024-05-311-1/+3
| | | | | It is currently an array of 32 uint8_t, each storing a single flag. A single uint32_t is sufficient.

* avutil/common: Don't auto-include mem.hAndreas Rheinhardt2024-03-311-0/+1
| | | | | | | | | | | There are lots of files that don't need it: The number of object files that actually need it went down from 2011 to 884 here. Keep it for external users in order to not cause breakages. Also improve the other headers a bit while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/hevc_ps: don't use a fixed sized buffer for parameter set raw dataJames Almer2024-03-291-68/+72
| | | | | | Allocate it instead, and use it to compare sets instead of the parsed struct. Signed-off-by: James Almer <jamrial@gmail.com>
* avcodec/hevc_ps: fix the problem of memcmp losing effectivenessTong Wu2024-03-291-4/+15
| | | | | | | | | | | HEVCHdrParams* receives a pointer which points to a dynamically allocated memory block. It causes the memcmp always returning 1. Add a function to do the comparision. A condition is also added to avoid malloc(0). Reviewed-by: James Almer <jamrial@gmail.com> Signed-off-by: Tong Wu <tong1.wu@intel.com> Signed-off-by: James Almer <jamrial@gmail.com>
* avcodec/hevc_ps: fix setting HEVCHdrParams fieldsJames Almer2024-03-211-20/+24
| | | | | | | | These were defined in a way compatible with the Vulkan HEVC acceleration, which expects bitmasks, yet the fields were being overwritting on each loop with the latest read value. Signed-off-by: James Almer <jamrial@gmail.com>

* avcodec/hevc_ps: Use RefStruct API for parameter setsAndreas Rheinhardt2023-10-071-46/+34
| | | | | | | | | | Avoids allocations and error checks for these allocations; e.g. syncing buffers across threads can't fail any more and needn't be checked. It also gets rid of casts and indirections. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* hevc_ps: fix fixed_rate checkllyyr2023-09-101-1/+2
| | | | | | | Fixes: fc429d785e9e24c5520ce716d4bc3b5547e581eb Since fc429d785e9e24c5520ce716d4bc3b5547e581eb splits the fixed_rate flag into general and within_cvs, check for both.
* hevc_ps: fix cpb_cnt_minus1 initializationllyyr2023-09-101-4/+2
| | | | | | | | | | | Fixes: fc429d785e9e24c5520ce716d4bc3b5547e581eb cpb_cnt used to be initialized to 1 before fc429d785e9e24c5520ce716d4bc3b5547e581eb so cpb_cnt_minus1 should be initialized to 0. Also add +1 to the decode_sublayer_hrd call to account for the change to the offset
* avcodec/defs: Add AV_PROFILE_* defines, deprecate FF_PROFILE_* definesAndreas Rheinhardt2023-09-071-6/+6
| | | | | | | | | These defines are also used in other contexts than just AVCodecContext ones, e.g. in libavformat. Furthermore, given that these defines are public, the AV-prefix is the right one, so deprecate (and not just move) the FF-macros. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/hevc_ps: Improve PPS SCC extension bit depth checkAndreas Rheinhardt2023-07-101-4/+6
| | | | | | | | | | | | From the spec: "It is a requirement of bitstream conformance that the value of luma_bit_depth_entry_minus8 shall be equal to the value of bit_depth_luma_minus8"; similarly for chroma. Also fixes Coverity ticket #1529226 (complaining about the fact that chroma_bit_depth_entry is checked twice).

* lavc/hevc_ps: Add SPS/PPS parse support for HEVC extension syntaxLinjie Fu2023-02-271-12/+277
| | | | | | | | | | | | 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().
