08ea7d6b8e lavc/hevcdec: constify source frame in hevc_ref_frame() 2024-06-11 17:39:35 +02:00
Anton Khirnov
ccd391d6a3 lavc/hevcdec: do not unref current frame on frame_end() failure 
It's a race with frame threading.

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.

edb6a471c4 lavc/hevcdec: factor decoding a slice NALU out of decode_nal_unit() 2024-06-11 17:39:35 +02:00

90e75c4ec9 lavc/hevcdec: drop a redundant multiple-frame-per-packet check 2024-06-11 17:39:35 +02:00
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.

a8f9d52c22 lavc/hevcdec: move setting slice_initialized out of hls_slice_header() 
hls_slice_header() no longer modifies anything in HEVCContext besides
SliceHeader.

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.
 2024-06-11 17:39:35 +02:00
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.

47d34ba7fb lavc/hevcdec: move constructing slice RPL to decode_slice_data() 2024-06-11 17:39:35 +02:00

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.

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.

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().
 2024-06-11 17:39:35 +02:00

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).
 2024-06-11 17:39:35 +02:00
Anton Khirnov
7cce612a26 lavc/hevcdec: move a slice segment sanity check to hls_slice_header() 
Combine it with an existing similar check.

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().

e4e9e1da15 lavc/hevcdec: drop redundant HEVCContext.threads_{type,number} 
They are useless duplicates of corresponding AVCodecContext fields.
 2024-06-11 17:39:35 +02:00

b0c29a45dc lavc/hevc/cabac: do not infer WPP use based on HEVCContext.threads_number 
Pass this information explicitly instead.

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.

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.

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().

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.

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.

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.

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.

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.

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.

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.
