* avcodec/mpegvideo: Enable private contextsAndreas Rheinhardt2022-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MpegEncContext is used by many different codecs and every one of these uses just a subset of its fields. If one tries to separate this and e.g. add a real MpegContext and extension structures (say MpegDecContext and MpegEncContext), one runs into two difficulties: a) Some code is shared between decoder and encoder of the same format and they therefore use the same contexts, either MpegEncContext itself or identical extensions thereof. The latter is the case for H.261 as well as WMV2. b) In case of slice threading, the generic code can only allocate and initialize the structure it knows about; right now this is an MpegEncContext. If the codec has an even more extensive structure, it is only available for the main thread's MpegEncContext. Fixing this would involve making ff_mpv_common_init() aware of the size the size of slice context to allocate and would be part of separating the main thread's context from the slice contexts in general. This commit only intends to tackle the first issue by adding a pointer to MpegEncContext that codecs can set to a common context so that the aforementioned codecs can use this context (together with the MpegEncContext) in their common code. This will allow to move fields only used by the main thread to more specialized contexts. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/vp6: return value check for av_malloczJiasheng Jiang2022-02-11
| | | | | | | | | | | | As the potential failure of the av_mallocz(), the 's->alpha_context' could be NULL and be dereferenced later. Therefore, it should be better to check it and deal with it if fails in order to prevent memory leak, same as the av_frame_alloc() in ff_vp56_init().

* avcodec/pthread_frame: Properly unref frame in case of decoding failureAndreas Rheinhardt2022-02-09
| | | | | | | | | | Use ff_thread_release_buffer() instead of av_frame_unref(), as the former handles the case of non-thread-safe callbacks properly.

* avcodec/thread: Don't use ThreadFrame when unnecessaryAndreas Rheinhardt2022-02-09
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | Several of our decoders support both frame- as well as slice-threading; in case of the latter avctx->internal->thread_ctx points to a SliceThreadContext, not to a frame-thread PerThreadContext. So only treat avctx->internal->thread_ctx as the latter after having checked that frame-threading is active.
