Anton Khirnov	08ea7d6b8e	lavc/hevcdec: constify source frame in hevc_ref_frame()	8 months ago
Anton Khirnov	ccd391d6a3	lavc/hevcdec: do not unref current frame on frame_end() failure It's a race with frame threading.	8 months ago
Anton Khirnov	d725c737fe	lavc/hevcdec: move some frame-end code to hevc_frame_end() Specifically, calling hwaccel end_frame, verifying frame checksum, and printing the frame-was-decoded message.	8 months ago
Anton Khirnov	edb6a471c4	lavc/hevcdec: factor decoding a slice NALU out of decode_nal_unit()	8 months ago
Anton Khirnov	90e75c4ec9	lavc/hevcdec: drop a redundant multiple-frame-per-packet check	8 months ago
Anton Khirnov	3cd6492fb5	lavc/hevcdec: move the check for multiple frames in a packet Do not do it in hls_slice_header(), which is the wrong place for it. Avoids special magic return value of 1 in that function. The comment mentioning potential corrupted state is no longer relevant, as hls_slice_header() modifies no state beyond SliceHeader, which will only get used for a valid frame.	8 months ago
Anton Khirnov	a8f9d52c22	lavc/hevcdec: move setting slice_initialized out of hls_slice_header() hls_slice_header() no longer modifies anything in HEVCContext besides SliceHeader.	8 months ago
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.	8 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.	8 months ago
Anton Khirnov	47d34ba7fb	lavc/hevcdec: move constructing slice RPL to decode_slice_data()	8 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.	8 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.	8 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().	8 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).	8 months ago
Anton Khirnov	7cce612a26	lavc/hevcdec: move a slice segment sanity check to hls_slice_header() Combine it with an existing similar check.	8 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().	8 months ago
Anton Khirnov	e4e9e1da15	lavc/hevcdec: drop redundant HEVCContext.threads_{type,number} They are useless duplicates of corresponding AVCodecContext fields.	8 months ago
Anton Khirnov	b0c29a45dc	lavc/hevc/cabac: do not infer WPP use based on HEVCContext.threads_number Pass this information explicitly instead.	8 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.	8 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.	8 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().	8 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.	8 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.	8 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.	8 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.	8 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.	8 months ago
Anton Khirnov	8eb134f4f9	lavc/hevcdec: drop an always-zero variable	8 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.	8 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.	8 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.	8 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.	8 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.	8 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.	8 months ago
Anton Khirnov	6ddba110eb	lavc/hevc/parser: stop using HEVCParamSets.[psv]ps The parser does not need to preserve these between frames.	8 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.	8 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.	8 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()	8 months ago
Anton Khirnov	a82f2b0924	lavc/hevcdec: simplify condition	8 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.	8 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
Anton Khirnov	9576a00527	lavc/hevcdec: drop unused HEVCContext.width/height	8 months ago
Anton Khirnov	a13b892080	lavc/hevcdec: deduplicate calling hwaccel decode_params()	8 months ago
Anton Khirnov	e4601cc339	lavc/hevc*: move to hevc/ subdir	8 months ago
