    avcodec/thread: Don't use ThreadFrame when unnecessary · 02220b88
    Andreas Rheinhardt authored
    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.
