* lavc/hevc_ps: do not store delta_poc_s[01] in ShortTermRPShevcAnton Khirnov2024-04-10
| | | | | | | They are only used in vulkan_hevc and are not actually needed, as they can be computed from delta_poc. Reduces sizeof(HEVCSPS) by 16kB.
* lavc/hevc_ps: fix variable signedness in ff_hevc_decode_short_term_rps()Anton Khirnov2024-04-10
| | | | | | It is actually supposed to go negative in the loop over num_negative pics, but underflow does not break anything as the result is then assigned to a signed int.
* lavc/hevc_ps/HEVCSPS: change flags into size-1 bitfieldsAnton Khirnov2024-04-10
| | | | | | | Reduces sizeof(HEVCSPS) by 96 bytes. Also improve flag names: drop redundant suffixes and prefixes, and consistently use disabled/enabled.
* lavc/hevc_ps: reduce the size of used_by_curr_pic_lt_sps_flagAnton Khirnov2024-04-10
| | | | | It is currently an array of 32 uint8_t, each storing a single flag. A single uint32_t is sufficient.
* lavc/hevcdec: drop a useless execute() call with 1 jobAnton Khirnov2024-04-10
|
* lavc/hevcdec: allocate local_ctx as array of structs rather than pointersAnton Khirnov2024-04-10
| | | | It is more efficient and easier to manage.
* lavc/hevcdec: track local context count separately from WPP thread countAnton Khirnov2024-04-07
| | | | The latter can be lowered while decoding, which would lead to memleaks.
* lavc/hevcdec: rename HEVCContext.HEVClcList to local_ctxAnton Khirnov2024-04-07
| | | | It is more consistent with our naming conventions.
* lavc/decode: reindent after previous commitAnton Khirnov2024-04-05

* lavc: convert frame threading to the receive_frame() patternAnton Khirnov2024-04-05
| | | | | | | | | Reorganize the code such that the frame threading code does not call the decoders directly, but instead calls back into the generic decoding code. This avoids duplicating the logic that wraps the decoder invocation and will be useful in the following commits. Further work by Timo Rothenpieler <timo@rothenpieler.org>.
* lavc/internal: document the precise meaning of AVCodecInternal.drainingAnton Khirnov2024-04-05
| | | | | | | Also, set draining=1 in case a bitstream filter returns an internally-triggered EOF. While no bitstream filters currently inserted by decoders will do that, that may change in the future and it is better to cover this case.
* lavc/thread: move generic-layer API to avcodec_internal.hAnton Khirnov2024-04-05
| | | | | | thread.h currently contains both API for decoder use and functions internal to lavc generic layer. Move the latter to avcodec_internal.h, which is a more appropriate place for them.
* fate/ffmpeg: Avoid dependency on samplesAndreas Rheinhardt2024-04-05
| | | | | | | | | | | | | | | Creating vsynth_lena.yuv needs the FATE suite, yet several tests in ffmpeg.mak without a dependency on samples used it as input file. Fix this by using vsynth1.yuv (which does not have such a dependency) instead. Also use vsynth1.yuv in fate-shortest to avoid the samples dependency in this test, too. Fixes ticket #10947.

* avcodec/dsd: Hoist branch out of loopAndreas Rheinhardt2024-04-04
| | | | | | | | This is possible by not converting from LSBF to MSBF; instead add LSBF LUTs. This approach necessitates reversing the initial values. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/dsddec: Fix decoding LSBF samplesAndreas Rheinhardt2024-04-04
| | | | | | | | | | ff_dsd2pcm_translate() works internally by converting LSBF input to MSBF upon reading; its buffer is therefore always MSBF and should therefore be initialized with MSBF silence; but this is not true since e3d8963c3cb5b8cd31460dd9b3b9dba2a2343bf5 which this patch effectively reverts.

* avcodec/wavpack: Fix leak and segfault on reallocation errorAndreas Rheinhardt2024-04-04
| | | | | | | | | | | | | | av_realloc_f() frees the buffer it is given on allocation failure. But in this case, the buffer is an array of ownership pointers, causing leaks on error. Furthermore, the count of pointers is unchanged on error and the codec's close function uses it to free said ownership pointers, causing a NPD. This is a regression since 46412a8935e4632b2460988bfce4152c7dccce22. Fix this by switching to av_realloc_array(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/lossless_videoencdsp: Don't presume alignment in diff_bytesAndreas Rheinhardt2024-04-04
| | | | | | | | | | | The alignment of all the parameters in diff_bytes can be anything the despite the documentation claiming otherwise. 8ecd38312210d48ec9e50d78fc223d60e71a30ed was based around said documentation and is therefore insufficient to fix e.g. the misaligned loads that happen in the huffyuvbgra and huffyuvbgr24 vsynth FATE-tests.

* avcodec/libx265: do not arbitrarily limit color valuesJan Ekström2024-04-03
| | | | | | | | | | | Newer specifications such as H.273 have, and probably will further in the future add new values to these, so - instead of trying to update these limits - we should simply check if the values are not set to the value of "unspecified". This should allow newer avutil values such as IPT-C2 or YCgCo-R variants be passed to x265 itself, which apparently does its own validation further down the line.

* avutil/pix{desc,fmt}: add new matrix coefficients from H.273 v3Jan Ekström2024-04-03
| | | | | | | | | | | | * SMPTE ST 2128 IPT-C2 defines the coefficients utilized in DoVi Profile 5. Profile 5 can thus now be represented in VUI as {AVCOL_RANGE_JPEG, AVCOL_PRI_BT2020, AVCOL_TRC_SMPTE2084, AVCOL_SPC_IPT_C2, AVCHROMA_LOC_LEFT} (although other chroma sample locations are allowed). AVCOL_TRC_SMPTE2084 should in this case be interpreted as 'PQ with reshaping'. * YCgCo-Re and YCgCo-Ro define the bitexact YCgCo-R, where the number of bits added to a source RGB bit depth is 2 (i.e., even) and 1 (i.e., odd), respectively.
