* lavc: do not implicitly share the frame pool between threadsAnton Khirnov2020-04-101-11/+2
| | | | | | | | | | | | | Currently the frame pool used by the default get_buffer2() implementation is a single struct, allocated when opening the decoder. A pointer to it is simply copied to each frame thread and we assume that no thread attempts to modify it at an unexpected time. This is rather fragile and potentially dangerous. With this commit, the frame pool is made refcounted, with the reference being propagated across threads along with other context variables. The frame pool is now also immutable - when the stream parameters change we drop the old reference and create a new one.

* lavc: implement an ATRAC9 decoderRostislav Pehlivanov2018-07-031-0/+1
| | | | | | | | | | | | | | | | | | | | This commit implements a full ATRAC9 decoder, a simple low-delay codec developed by Sony and used in most PSVita games, some PS3 games and some PS4 games. Its similar to AAC in that it uses Huffman coded scalefactors but instead of vector quantization it just Huffman codes the spectral coefficients (in a way similar to how Opus splits band energy coding into coarse and fine precision). It opts to write rather large Huffman codes by packing several small coefficients into one Huffman coded symbol, though I don't believe this increases efficiency at all. Band extension implements SBC in a simple way, first it mirrors the lower spectrum onto the higher frequencies and then it uses one of 5 filters to shape it. Noise substitution is implemented via 2 of them. Unlike previous ATRAC codecs, there's no QMF, this is a standard MDCT codec. Based off of the reverse engineering work of Alex Barney.

* lavc: remove complex debug code around avcodec init lockingwm42017-12-261-41/+14
| | | | | | | | | | | | | | | | | | | | | This is just a lot of complicated and confusing code that had no purpose anymore. Also, the functions return values were checked only sometimes. Locking shouldn't fail anyway, so remove the return values. Barely any other pthread lock calls check the return value (including more important code that is more likely to fail horribly if locking fails). It could be argued that it might be helpful in some debugging situations, or when the user built FFmpeg without thread support against all good advice. But there are dummy atomics too, so the atomic check won't help with ensuring correctness absolutely. You gain very little. Also, for debugging, you can just raise the ASSERT_LEVEL, and then libavutil/thread.h will redefine the locking functions to explicitly check the return values.
* lavc, lavf: move avformat static mutex from avcodec to avformatwm42017-12-261-11/+0
| | | | | | | | It's completely absurd that libavcodec would care about libavformat locking, but it was there because the lock manager was in libavcodec. This is more stright forward. Changes ABI, but we don't require ABI compatibility currently.
* lavc: replace and deprecate the lock managerwm42017-12-261-97/+10
| | | | | | | Use static mutexes instead of requiring a lock manager. The behavior should be roughly the same before and after this change for API users which did not set the lock manager at all (except that a minor memory leak disappears).
* Revert "libavcodec/utils.c: simplify avcodec locking with atomics"Hendrik Leppkes2017-12-111-6/+6
| | | | | | | | | | This reverts commit 590136e78da3d091ea99ab5432543d47a559a461. Atomics are not required for this variable, because it is protected through the lock manager, and the use of atomics here is not compatible with the c11 emulation wrappersi. Fixes FATE on MSVC, among other setups which use the compat wrappers.
