  avcodec/mpeg12dec: Don't reinit upon aspect ratio change
  
  The spec indeed does not allow the aspect ratio to change
  within a video sequence, but this does not imply that we
  must reinitialize the decoder if only the aspect ratio changes,
  as this value does not affect the decoding process at all.
  Moreover, our reinitialization is a bit buggy: If there is
  frame reordering, then the not yet output next P-frame is
  simply discarded upon reinit. With this patch this no longer
  happens when only the aspect ratio changes.

• avcodec/mpeg4videodec : Don't set chroma matrices unnecessarily

  avcodec/mpeg4videodec: Don't set chroma matrices unnecessarily
  
  Only the studio profile uses chroma_inter/intra matrices;
  the ordinary profile has only inter/intra matrices.
  And our code (namely the MPEG-2 unquantize functions)
  only use these two matrices (the MPEG-2 decoder unquantizes
  on its own while parsing).
