* avcodec/error_resilience: Only keep what is needed from MECmpContextAndreas Rheinhardt2022-05-19
| | | | | | | | | ERContext currently has an embedded MECmpContext, despite only needing exactly one function from it. This is wasteful because MECmpContext is pretty large (135 pointers, 1080 B for eight byte pointers). So keep only what is needed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* 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.

| * error_resilience: move the MECmpContext initialization into ER codeAnton Khirnov2015-01-27
| | | | | | | | | | | | | | Currently, it needs to be initialized by the ER caller (which is currently either a mpegvideo decoder or h264dec). However, since none of those decoders use MECmpContext for anything except ER, it makes more sense to handle it purely inside ER.

| | | | | | | | | | | | | | This is done to disentangle ER from mpegvideo. In order to use a classic Picture, callers can use ff_mpeg_set_erpic() or use a custom function to set the fields. Please note that buffers need to be allocated before calling ff_er_frame_end().
