• avcodec/av1dec : Use ProgressFrames

  19 avril, par Andreas Rheinhardt

  avcodec/av1dec: Use ProgressFrames
  
  AV1 can put a frame into multiple reference slots;
  up until now, this involved creating a new reference
  to the underlying AVFrame; therefore av1_frame_ref()
  could fail.
  This commit changes this by using the ProgressFrame API
  to share the underlying AVFrames.
  
  (Hint: vaapi_av1_surface_id() checked whether the AV1Frames
  contained in the AV1DecContext were NULL or not (of course
  they were not); this has been changed to actually check for
  whether said AV1Frame is blank or not.)

• lavc/vvc/refs : Use dpb_max_num_reorder_pics to control output

  lavc/vvc/refs: Use dpb_max_num_reorder_pics to control output
  
  Use dpb_max_num_reorder_pics to control output instead of
  dpb_max_dec_pic_buffering, when dpb_max_dec_pic_buffering
  is much larger than dpb_max_num_reorder_pics, it may cause
  dpb overflow error.

  lavc/vvc_parser: Fixed the has_b_frames setting
  
  has_b_frames used in decoder for size of the frame reordering
  buffer, setting this field from dpb_max_num_reorder_pics.

• avcodec/hevcdec : Use union for AVFrame* and ProgressFrame

  19 avril, par Andreas Rheinhardt

  avcodec/hevcdec: Use union for AVFrame* and ProgressFrame
  
  It avoids having to sync ProgressFrame.f and the pointer
  typically used to access the AVFrame.
