* avcodec/huffyuv(dec|enc): Use union for temp/temp16Andreas Rheinhardt2024-04-07
| | | | | | | | These pointers already point to the same buffers, so using a union is possible and avoids the overhead of syncing the pointers (and saves some memory). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* lavc/vvc: Error if SPS ID is duplicated within CVSFrank Plowman2024-04-07
| | | | | | | | | | | | | | | | | | | | Key line from the spec is: "All SPS NAL units with a particular value of sps_seq_parameter_set_id in a CVS shall have the same content." Prior to this patch, the VVC decoder's behaviour on encountering a duplicated SPS ID (within the entire bitstream, not restricted to a CVS) was simply to replace the entry in the SPS lookup table with the new data. Illegal bitstreams with multiple SPSs in the same CVS sharing an ID but differing elsewhere could cause all manner of issues. The patch tracks which SPS IDs have been used in the given CVS using the new sps_id_used field of VVCParamSets. If it encounters an SPS with an ID already in use and whose content differs from the previous SPS, it throws an AVERROR_INVALIDDATA. Signed-off-by: Frank Plowman <post@frankplowman.com>

* avocdec/ass: simplify linebreaksOneric2024-04-06
| | | | | | ff_ass_subtitle_header_* still used explicit CRLF linebreaks eventhough they will get normalised to LF later since commit 7bf1b9b35769b37684dd2f18a54f01d852a540c8. Just directly use LF.
* avcodec/ass,webvttdec: implement more portable curly brace escapesOneric2024-04-06
| | | | | | | | | | | | | Unlike what the old comment suggested, standard ASS has no character escape mechanism, but a closing curly bracket doesn't even need one. For manual authored sub files using a full-width variant of an appropriate font and with scaling and spacing modifiers is a common workaround. This is not an option here, but we can still make things much less bad. Now the desired opening bracket still shows up in libass, and standard renders will merely display a backslash in its place instead of stripping the following text like before.
* avcodec/ass,webvttdec: fix handling of backslashesOneric2024-04-06
| | | | | | | Backslashes cannot be escaped by a backslash in any ASS renderer, but unless followed by specific characters it is just printed out. Insert a word-joiner character after a backslash to break up active sequences without changing the visual output.

* avcodec/libaomenc: bump the minimum required version to 2.0.0James Almer2024-04-05
| | | | | | | | v2.0.0 is already four years old and even newer versions are available on stable distro releases. With this we stop setting codec capabilities during static data initialization. Signed-off-by: James Almer <jamrial@gmail.com>
* 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.
