  avcodec/mpeg4videodec: Avoid copying packed bitstream data
  
  This is possible because the packet is reference-counted
  and because we never combine the data from several packets.

  tests/swscale: switch from MSE to SSIM
  
  And bias it towards Y. This is much better at ignoring errors due to differing
  dither patterns, and rewards algorithms that lower luma noise at the cost of
  higher chroma noise.
  
  The (0.8, 0.1, 0.1) weights for YCbCr are taken from the paper:
    "Understanding SSIM" by Jim Nilsson and Tomas Akenine-Möller
    (https://arxiv.org/abs/2006.13846)

  tests/swscale: use yuva444p as reference
  
  Instead of the lossy yuva420p. This does change the results compared to the
  status quo, but is more reflective of the actual strength of a conversion,
  since it will faithfully measure the round-trip error from subsampling and
  upsampling.

  avutil/frame: Port AVFrame.private_ref to RefStruct API
  
  This is possible without deprecation period, because said field
  is documented as only for our libav* libraries and not the general
  public.
