* avcodec/pthread_slice: Combine allocating and zeroing entriesAndreas Rheinhardt2022-07-251-2/+1
| | | | | | | | | Actually, ff_slice_thread_allocz_entries() always already allocates zeroed entries, so ff_reset_entries() was already unnecessary. Make this more clear by renaming it to ff_slice_thread_allocz_entries(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/pthread_slice: Don't reinitialise initialised mutexAndreas Rheinhardt2022-07-011-0/+1
| | | | | | | | | | | | | | It results in undefined behaviour. Instead initialize the mutexes and condition variables once during init (and check these initializations). Also combine the corresponding mutex and condition variable into one structure so that one can allocate their array jointly.

* avcodec/codec_internal: Add FFCodec, hide internal part of AVCodecAndreas Rheinhardt2022-03-211-2/+2
| | | | | | | | | | | | | | | | Up until now, codec.h contains both public and private parts of AVCodec. This exposes the internals of AVCodec to users and leads them into the temptation of actually using them and forces us to forward-declare structures and types that users can't use at all. This commit changes this by adding a new structure FFCodec to codec_internal.h that extends AVCodec, i.e. contains the public AVCodec as first member; the private fields of AVCodec are moved to this structure, leaving codec.h clean.

* avcodec/thread: Don't use ThreadFrame when unnecessaryAndreas Rheinhardt2022-02-091-12/+2
| | | | | | | | | | | | | | | | | | | | | | | The majority of frame-threaded decoders (mainly the intra-only) need exactly one part of ThreadFrame: The AVFrame. They don't need the owners nor the progress, yet they had to use it because ff_thread_(get|release)_buffer() requires it. This commit changes this and makes these functions work with ordinary AVFrames; the decoders that need the extra fields for progress use ff_thread_(get|release)_ext_buffer() which work exactly as ff_thread_(get|release)_buffer() used to do. This also avoids some unnecessary allocations of progress AVBuffers, namely for H.264 and HEVC film grain frames: These frames are not used for synchronization and therefore don't need a ThreadFrame. Also move the ThreadFrame structure as well as ff_thread_ref_frame() to threadframe.h, the header for frame-threaded decoders with inter-frame dependencies.

* avcodec/thread: Move ff_thread_(await|report)_progress to new headerAndreas Rheinhardt2022-02-091-26/+0
| | | | | | | | | | This is in preparation for further commits that will stop using ThreadFrame for frame-threaded codecs that don't use ff_thread_(await|report)_progress(); the API for those codecs having inter-frame depdendencies will live in threadframe.h.

* avcodec: deprecate thread_safe_callbacksAnton Khirnov2020-11-271-0/+4
| | | | | | | | | They add considerable complexity to frame-threading implementation, which includes an unavoidably leaking error path, while the advantages of this option to the users are highly dubious. It should be always possible and desirable for the callers to make their get_buffer2() implementation thread-safe, so deprecate this option.

* | pthread_frame: allow per-field ThreadFrame owners.Ronald S. Bultje2017-04-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This tries to handle cases where separate invocations of decode_frame() (each running in separate threads) write to respective fields in the same AVFrame->data[]. Having per-field owners makes interaction between readers (the referencing thread) and writers (the decoding thread) slightly more optimal if both accesses are field-based, since they will use the respective producer's thread objects (mutex/cond) instead of sharing the thread objects of the first field's producer. In practice, this fixes the following tsan-warning in fate-h264: WARNING: ThreadSanitizer: data race (pid=21615) Read of size 4 at 0x7d640000d9fc by thread T2 (mutexes: write M1006): #0 ff_thread_report_progress pthread_frame.c:569 (ffmpeg:x86_64+0x100f7cf54) [..] Previous write of size 4 at 0x7d640000d9fc by main thread (mutexes: write M1004): #0 update_context_from_user pthread_frame.c:335 (ffmpeg:x86_64+0x100f81abb)
