Anton Khirnov	0892ec947c	lavc/hevcdec: pass SliceHeader explicitly to pred_weight_table() And replace the HEVCContext* parameter by void *logctx. Makes it clear that only SliceHeader is modified by this function.	7 months ago
Anton Khirnov	90fc331b0f	lavc/hevcdec: only ignore INVALIDDATA in decode_nal_unit() All other errors should cause a failure, regardless of the value of err_recognition. Also, print a warning message when skipping invalid NAL units.	7 months ago
Anton Khirnov	8eb134f4f9	lavc/hevcdec: drop an always-zero variable	7 months ago
Anton Khirnov	8c8072c29c	lavc/hevcdec: move active PPS from HEVCParamSets to HEVCContext "Currently active PPS" is a property of the decoding process, not of the list of available parameter sets.	7 months ago
Anton Khirnov	0f47342c12	lavc/hevcdec: stop accessing parameter sets through HEVCParamSets Instead, accept PPS/SPS as function arguments. Makes the code shorter and significantly reduces diff in future commits.	7 months ago
Anton Khirnov	38b8ae4112	lavc/hevc/pred: stop accessing parameter sets through HEVCParamSets Instead, accept PPS/SPS as function arguments. Makes the code shorter and significantly reduces diff in future commits.	7 months ago

Anton Khirnov	b38aecffec	lavc/hevc/filter: stop accessing parameter sets through HEVCParamSets Instead, accept PPS as a function argument and retrieve SPS through it. Makes the code shorter and significantly reduces diff in future commits.	7 months ago
Anton Khirnov	fb873a05b3	lavc/hevc/mvs: stop accessing parameter sets through HEVCParamSets Instead, accept PPS as a function argument and retrieve SPS through it. Makes the code shorter and significantly reduces diff in future commits.	7 months ago
Anton Khirnov	6ddba110eb	lavc/hevc/parser: stop using HEVCParamSets.[psv]ps The parser does not need to preserve these between frames.	7 months ago
Anton Khirnov	2e46d68f55	lavc/hevc_ps: make SPS hold a reference to its VPS SPS and its dependent PPSes depend on, and are parsed for, specific VPS data. This will be useful in following commits.	7 months ago
Anton Khirnov	c879165b39	lavc/hevc_ps: make PPS hold a reference to its SPS PPS depends on, and is parsed for, specific SPS data. This will be useful in following commits.	7 months ago
Anton Khirnov	e12fd62d1d	lavc/hevcdec: drop a redundant assignment in hevc_decode_frame() The exact same code is executed at the beginning of decode_nal_units()	7 months ago
Anton Khirnov	a82f2b0924	lavc/hevcdec: simplify condition	7 months ago
Anton Khirnov	0407556716	lavc/hevcdec: do not free SliceHeader arrays in pic_arrays_free() SliceHeader.{entry_point_offset,size,offset} are not derived from frame size and do not need to be freed here.	7 months ago
Rémi Denis-Courmont	b6f37ffba7	lavc/vc1dsp: match C block layout in inv_trans_4x8_rvv Although checkasm does not verify this, the decoder requires that the transform updates the input block exactly like the C code does. This fixes vc1-ism, vc1_ilaced_twomv, vc1_sa00040, vc1_sa10091, vc1_sa10143, vc1_sa20021, vc1test_smm0005 and wmv3-drm-dec tests.	7 months ago

Andreas Rheinhardt	a0ff31e740	avcodec/vvc/inter: Don't return void Returning a void is not allowed by the spec. Just return instead. Reviewed-by: Nuo Mi <nuomi2021@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	7 months ago

Andreas Rheinhardt	dd8fb0aaae	avcodec/hevc/Makefile: Move rules for lavc/* files to lavc/Makefile If any of these files (say A) would be changed in such a way that A acquires a new dependency on another file B, building B would need to be added to all the rules that lead to A being built. Yet currently the rules for several files are spread over the lavc Makefile and the Makefile of the lavc/hevc subdir, making it more likely to be forgotten. So move the rules for these files to the lavc/Makefile. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	8 months ago

Lynne	1ad9a4008b	aacdec_usac: decouple TNS active from TNS data present flag The issue was that in case of common TNS parameters, TNS was entirely skipped, as tns.present was set to 0.	8 months ago

Lynne	ee419804da	mpeg4audio: explicitly define each AOT This makes it far easier to figure out which AOT belongs to which profile. Also, explicitly highlight the holes.	8 months ago
Lynne	8a2fe8a5b9	mpeg4audio: rename AOT_USAC_NOSBR to AOT_USAC The issue is that AOT 45 isn't defined anywhere, and looking at the git blame, it seems to have sprung up through a reordering of the enum, and adding a hole. The spec does not define an explicit AOT for SBR and no SBR, and only uses AOT 42 (previously AOT_USAC_NOSBR), so just rename AOT_USAC to it and replace its use everywhere.	8 months ago
