| | | | | | | Use the decoded frame's sample_rate instead, which is the authoritative value. Drop a now-obsolete check validating AVCodecContext.sample_rate.

* avformat: Rename IPFS to IPFS gatewayDerek Buitenhuis2023-01-09
| | | | | | | It is a URL rewriter for IPFS gateways, not an actual implementation of IPFS, and naming it as such was both incorrect and misleading. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

* mov: Disable advanced_editlist for fragmented MP4 inputDerek Buitenhuis2023-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Advanced edit list support is entirely broken for fragmented MP4s, currently. mov_fix_index is never run in mov_build_index, since in fragmented MP4s the stco, stsz, stts, and stsc boxes have zero entries, with the index being filled in as each fragment's trun box is seen. The result of this is that the skip samples is never set properly, since half the code thinks it doesn't need to, as advanced_editlist is enabled, but as mov_fix_index is never called, it doesnt get set. This means that any edits for e.g. priming are not properly applied as skip samples side data. This also means remuxing to fragmented MP4 from progressive MP4 with lavf will quietly drop the edit list, currently. Example: $ ffmpeg -loglevel quiet -advanced_editlist 1 -i non_fragmented.mp4 -f md5 - MD5=d02d929f8eb4edef624758a298d5f7c6 $ ffmpeg -loglevel quiet -advanced_editlist 0 -i non_fragmented.mp4 -f md5 - MD5=d02d929f8eb4edef624758a298d5f7c6 $ ffmpeg -loglevel quiet -advanced_editlist 1 -i fragmented.mp4 -f md5 - MD5=e38b110f586fa886ff94e0ca98a95d59 <-- wrong, extra samples are output instead of being skipped $ ffmpeg -loglevel quiet -advanced_editlist 0 -i fragmented.mp4 -f md5 - MD5=d02d929f8eb4edef624758a298d5f7c6 We cannot call mov_fix_index after reading a trun box since mov_fix_index seems to assume it is only called once, on a fully complete index, an multiple calls to it don't seem like they'd work, so the "best" option seems to be disabling advanced edit list support entirely for the time being, as it is broken for these types of files.

* lavc: add standalone cached bitstream readerAlexandra Hájková2023-01-06
| | | | | | | | | | | | | | | | | | | | The cached bitstream reader was originally written by Alexandra Hájková for Libav, with significant input from Kostya Shishkov and Luca Barbato. It was then committed to FFmpeg in ca079b09549, by merging it with the implementation of the current bitstream reader. This merge makes the code of get_bits.h significantly harder to read, since it now contains two different bitstream readers interleaved with #ifdefs. Additionally, the code was committed without proper authorship attribution. This commit re-adds the cached bitstream reader as a standalone header, as it was originally developed. It will be made useful in following commits. Integration by Anton Khirnov. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* swresample/swresample_frame: fix regression in detecting changesPaul B Mahol2023-01-04
| | | | | Do not overwrite return variable values, instead use different one for checking results.
* lavc/libx265: restructure handling reordered_opaqueAnton Khirnov2023-01-04
| | | | | | | | | | Current code stores a pointer to allocated data in libx265 and frees it when the encoded packet is retrieved. This will leak if the packet is never retrieved, e.g. if the encoder is closed without being flushed. Restructure the code such that only indices to an array stored in our private data are given to libx265. This ensures no allocated memory can be lost.
