  avcodec/mpeg12dec: Don't initialize unused parts of ScanTable
  
  The MPEG-1/2 decoders don't need ScanTable.raster_end
  (as the coefficients are unquantized as they are parsed).

  avcodec/h26[134]dec: Always report the buffer to be completely consumed
  
  It is pointless to try to report the true number because
  decode_simple_internal() always treats the buffer as
  completely consumed for video codecs anyway.
  (Apart from that: The h263dec code would report to only
  have consumed the header data in case decoding is aborted
  due to skip_frame which makes no sense.)

  avcodec/mpeg4videoenc: Remove dead FF_BUG_MS code
  
  Added in 59fa3f96f48d12e189492ca3670991f91c316d4e,
  yet avctx->workaround_bugs is never copied to
  MpegEncContext.workaround_bugs, so this code is dead
  (it seems that this was true even when it was added).
  Furthermore, workaround_bugs is flagged as decoder-only,
  so just remove the code.

  avcodec/vc1: Add max_b_frames field to VC1Context
  
  Don't reuse MpegEncContext.max_b_frames, which is supposed
  to be encoder-only.

• avcodec/mpegvideo_dec : Move syncing DivX-stuff to mpeg4videodec.c

  24 février, par Andreas Rheinhardt

  avcodec/mpegvideo_dec: Move syncing DivX-stuff to mpeg4videodec.c
  
  It is only used by MPEG-4 (and is used in h263dec.c and can therefore
  not just be moved to Mpeg4DecContext...).
