* 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.

* avcodec/av1dec: infer and store film grain param values in AV1FrameJames Almer2020-11-30
| | | | | | | | | They are not always coded in the bistream for each frame. In some cases, the values need to be taken from a reference frame. See section 6.8.20 from the AV1 spec. Signed-off-by: James Almer <jamrial@gmail.com>

* avcodec: add AV1 hardware accelerated decoderFei Wang2020-09-12
This AV1 decoder is currently only used for hardware accelerated decoding. It can be extended into a native decoder in the future, so set its name to "av1" and temporarily give it the lowest priority in the codec list.
