Anton Khirnov	82ded1ad3a	lavc/hevcdec: move sequence increment/IDR handling to hevc_frame_start() From hls_slice_header(). It is only done once per frame, so that is a more appropriate place for this code.	9 months ago
Anton Khirnov	a2e77caf37	lavc/hevcdec: set active PPS/SPS in hevc_frame_start() Not in hls_slice_header(), as it should only be done once per frame.	9 months ago
Anton Khirnov	47d34ba7fb	lavc/hevcdec: move constructing slice RPL to decode_slice_data()	9 months ago
Anton Khirnov	fe171a3b51	lavc/hevcdec: move calling hwaccel decode_slice to decode_slice_data() From decode_nal_unit(), as that is a more appropriate place for it.	9 months ago
Anton Khirnov	6ee550d83d	lavc/hevcdec: move calling hwaccel start_frame to hevc_frame_start() From decode_nal_unit(), as that is a more appropriate place for it.	9 months ago
Anton Khirnov	3bbb5d78c7	lavc/hevcdec: move per-slice local_ctx setup out of hls_slice_header() Into decode_slice_data(). This is a step towards constifying HEVCContext in hls_slice_header().	9 months ago
Anton Khirnov	efc827bf6f	lavc/hevcdec: move slice decoding dispatch to its own function Also move there a sanity check from hls_decode_entry() that should also be performed when WPP is active (note that the check is not moved to hls_slice_header() because it requires the HEVCContext.tab_slice_address to be set up).	9 months ago
Anton Khirnov	7cce612a26	lavc/hevcdec: move a slice segment sanity check to hls_slice_header() Combine it with an existing similar check.	9 months ago
Anton Khirnov	d43527a1a0	lavc/hevcdec: store slice header POC in SliceHeader Rather than decoding directly into HEVCContext.poc. This is a step towards constifying HEVCContext in hls_slice_header().	9 months ago
Anton Khirnov	e4e9e1da15	lavc/hevcdec: drop redundant HEVCContext.threads_{type,number} They are useless duplicates of corresponding AVCodecContext fields.	9 months ago
Anton Khirnov	b0c29a45dc	lavc/hevc/cabac: do not infer WPP use based on HEVCContext.threads_number Pass this information explicitly instead.	9 months ago
Anton Khirnov	d86ac94df2	lavc/hevcdec: output RASL frames based on the value of no_rasl_output_flag Instead of an ad-hoc scheme. Also, combine skipping RASL frames with skip_frame handling - current code seems flawed as it only executes for the first slice of a RASL frame and unnecessarily unsets is_decoded, which should not be set at this point anyway.. Some RASL frames in fate-hevc-afd-tc-sei that were previously discarded are now output.	9 months ago
Anton Khirnov	3115c84015	lavc/hevcdec: only set no_rasl_output_flag for IRAP frames Its meaning is only specified for IRAP frames. As it's currently never used otherwise, this should not change decoder behaviour, but will be useful in future commits.	9 months ago
Anton Khirnov	381b70e173	lavc/hevcdec: do not pass HEVCContext to ff_hevc_frame_nb_refs() Pass the only things required from it - slice header and PPS - explicitly. Will be useful in the following commits to avoid mofiying HEVCContext in hls_slice_header().	9 months ago
Anton Khirnov	07eb60c0da	lavc/hevcdec: only call export_stream_params_from_sei() once per frame Not once per each slice header, as it makes no sense and may cause races with frame threading.	9 months ago
Anton Khirnov	01b379a93e	lavc/hevcdec: move pocTid0 computation to hevc_frame_start() It is only done once per frame. Also, rename the variable to poc_tid0 to be consistent with our naming conventions.	9 months ago
Anton Khirnov	5e438511ab	lavc/hevcdec: do not pass HEVCContext to decode_lt_rps() Pass the two numbers needed from it explicitly. Makes it clear that HEVCContext is not modified by this function.	9 months ago
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.	9 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.	9 months ago
Anton Khirnov	8eb134f4f9	lavc/hevcdec: drop an always-zero variable	9 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.	9 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.	9 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.	9 months ago
Anton Khirnov	d0868d70ea	lavc/hevc/cabac: stop accessing parameter sets through HEVCParamSets Instead, accept PPS/SPS as function arguments. Makes the code shorter and significantly reduces diff in future commits.	9 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.	9 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.	9 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.	9 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.	9 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()	9 months ago
Anton Khirnov	a82f2b0924	lavc/hevcdec: simplify condition	9 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.	9 months ago
Anton Khirnov	a13b892080	lavc/hevcdec: deduplicate calling hwaccel decode_params()	9 months ago
Anton Khirnov	e4601cc339	lavc/hevc*: move to hevc/ subdir	9 months ago
Anton Khirnov	ba56a300a9	lavc/hevcdec: drop HEVCContext.frame It is merely a redundant pointer to cur_frame->f	9 months ago
Anton Khirnov	db84c1c6ef	lavc/hevcdec: rename HEVCFrame.frame to just f This is shorter, loses no information, and is consistent with other similar structs.	9 months ago
Anton Khirnov	9226514ced	lavc/hevcdec: rename HEVCContext.ref to cur_frame Since it stores a pointer to the current frame.	9 months ago
Anton Khirnov	7ad9400952	lavc/hevcdec: drop HEVCContext.HEVClc It is merely a pointer to local_ctx[0], which we can just as well use directly.	9 months ago
Anton Khirnov	67ca18dd56	lavc/hevcdec: drop HEVCLocalContext.gb In all HEVCLocalContext instances except the first one, the bitreader is never used for actually reading bits, but merely for passing the buffer to ff_init_cabac_decoder(), which is better done directly. The instance that actually is used for bitreading gets moved to stack in decode_nal_unit(), which makes its lifetime clearer.	9 months ago
Anton Khirnov	ac69e6caf6	lavc/hevcdec: include first row in SliceHeader.offset/size Will be useful in the following commit.	9 months ago
Anton Khirnov	79c0310aca	lavc/hevcdec: drop a useless condition hls_slice_data_wpp() is only called when num_entry_point_offsets>0	9 months ago
Anton Khirnov	74159cbfc3	lavc/hevcdec: move handling of byte alignment at the end of slice header Do it in hls_slice_header() rather than cabac_init_decoder() - the former is a more logical place as according the spec the byte alignment is a part of the slice header, not slice data. Avoids a second instance of alignment handling in vaapi_hevc. Also, check that alignment_bit_equal_to_one is, in fact, equal to one.	9 months ago
Anton Khirnov	6fed1841a1	lavc/hevc_ps/HEVCSPS: change flags into uint8_t Reduces sizeof(HEVCSPS) by 64 bytes. Also improve flag names: drop redundant suffixes and prefixes, and consistently use disabled/enabled.	9 months ago
Anton Khirnov	bd1a06dc43	lavc/hevc_ps: reduce the size of used_by_curr_pic_lt_sps_flag It is currently an array of 32 uint8_t, each storing a single flag. A single uint32_t is sufficient.	9 months ago
Anton Khirnov	72bdbce00d	lavc/hevcdec: drop a useless execute() call with 1 job	9 months ago
Anton Khirnov	f0aece90d9	lavc/hevcdec: allocate local_ctx as array of structs rather than pointers It is more efficient and easier to manage.	9 months ago
Anton Khirnov	25ce44efa5	lavc/hevcdec: track local context count separately from WPP thread count The latter can be lowered while decoding, which would lead to memleaks.	9 months ago
Anton Khirnov	a1471ec8ad	lavc/hevcdec: rename HEVCContext.HEVClcList to local_ctx It is more consistent with our naming conventions.	9 months ago
Michael Niedermayer	5eb05f4450	avcodec/hevcdec: Check ref frame Fixes: NULL pointer dereferences Fixes: 68197/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_HEVC_fuzzer-6382538823106560 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Reviewed-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	11 months ago
Niklas Haas	d0392619a7	avcodec/dovi_rpu: store entire config record And make it public. For encoding, users may also be interested in the configured level and compatibility ID. So generalize the dv_profile field and just expose the whole configuration record. This makes the already rather reductive ff_dovi_update_cfg() function almost wholly redundant, since users can just directly assign DOVIContext.cfg.	11 months ago
Andreas Rheinhardt	0ec886ddc7	avcodec/hevcdec: Use union for AVFrame* and ProgressFrame It avoids having to sync ProgressFrame.f and the pointer typically used to access the AVFrame. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	11 months ago
