| | | | | | | | | This allows to avoid the codes table; furthermore, given that the runs fit into seven bits and level into nine, one can put them into one int16_t and use as symbols table in ff_vlc_init_from_lengths(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/hq_hqadata: Avoid relocationsAndreas Rheinhardt2025-04-132-251/+268
| | | | | | | | | | | | Initialize a list of 128 pointers at decoder init instead of using a const list of pointers (which will be initialized at runtime when libavcodec is loaded when using pic code with Elf); the former takes only 128 bytes (+ a bit of initialization code), the latter 1KiB on 64 bit systems (+3KiB on x64 elf for relocation information).

* avcodec/hq_hqa: Don't zero in small chunks, don't zero twiceAndreas Rheinhardt2025-04-131-4/+3
| | | | | | | | | | | | | | Up until now, hq_decode_block() zeroed every block (of 128 bytes) before decoding a block; yet this is suboptimal for all modes, because all modes need to reset all the blocks they use anyway and so it should be done in one go for all blocks. For the alpha mode (where blocks need not be coded) all blocks are zeroed initially anyway, because decode_block() might not be doing it, so zeroing there again for the coded blocks is a waste.

* avcodec/hq{xvlc,_hqadata}: Deduplicate and hardcode cbp tableAndreas Rheinhardt2025-04-137-37/+82
| | | | | | | | | | This table is so small (32 elements amounting to 128 bytes) that it is more efficient size-wise to hardcode it instead of initializing it at runtime. Also stop duplicating it in hq_hqa.o and hqx.o. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/mediacodecdec: Reset optional fields when parse formatZhao Zhili2025-04-111-0/+2
| | | | | | | | | Parse format can be called multiple times, e.g., when resolution changed. If getInt32 fails, optional member variables will retain their previously set values without modification. This can be a big problem for new resolution with old crop info. This patch reset optional fields to zero when getInt32 failed.

* tests/fate/vcodec: Test "default" Huffman tables, tooAndreas Rheinhardt2025-04-0910-46/+46
| | | | | | | | | | | | | | Since 45eeb1f785d6c726181568db341bbf80b43e32c0 optimal Huffman tables are the default (without slice-threading). This made the fate-vsynth*-mjpeg-{trell-,}-huffman tests identical to their corresponding tests without "-huffman". This is of course wasteful, so switch the two tests with "-huffman" counterparts back to the default tables. Also use one of these tests to test slice threaded encoding. It has so far been untested.

| | | | | | | | | | | | | | | | | | | | | | | | | | Given that there are actually ASM functions of this type, one can't simply remove the ff_ prefix from the definitions and declare them as static. Yet one can do nearly that if one keeps the ff_ prefix and removes the declarations for the (now static) functions defined in dsp_init.c from hevcdsp.h and if one defines the functions in the correct order (smaller width first) so that no forward declarations are necessary (which was already true). The new declarations avoid nested macros to simplify things. It nevertheless turned out to be beneficial line-wise. (It would be possible to avoid most of these declarations: It is legal to repeat a function declaration without static if the first declaration declared a function as static. So if the macros simply declared all the functions that they call, one could avoid declarations for the functions that are called. While this is legal C, it unfortuntaly clashes with GCC's -Wredundant-decls (which configure enables) and it is also ugly, as these macro definitions would provide declarations used in ff_hevc_dsp_init_x86().)
