  dsputil_mmx: Honor HAVE_AMD3DNOW
  lavf,lavd: remove all usage of AVFormatParameters from demuxers.
  jack: add 'channels' private option.
  VC-1: fix reading of custom PAR.
  Remove redundant and dubious video codec detection by its extradata
  mpeg12: remove repeat-field code disabled since May 2002
  patch checklist: suggest fate instead of regression tests
  Turn on resampling on sudden size change instead of bailing out during recode.
  avtools: reinitialise filter chain when input video stream changes dimensions
