Michael Niedermayer 268098d8b2 Merge remote-tracking branch 'qatar/master'
* qatar/master: (29 commits)
  amrwb: remove duplicate arguments from extrapolate_isf().
  amrwb: error out early if mode is invalid.
  h264: change underread for 10bit QPEL to overread.
  matroska: check buffer size for RM-style byte reordering.
  vp8: disable mmx functions with sse/sse2 counterparts on x86-64.
  vp8: change int stride to ptrdiff_t stride.
  wma: fix invalid buffer size assumptions causing random overreads.
  Windows Media Audio Lossless decoder
  rv10/20: Fix slice overflow with checked bitstream reader.
  h263dec: Disallow width/height changing with frame threads.
  rv10/20: Fix a buffer overread caused by losing track of the remaining buffer size.
  rmdec: Honor .RMF tag size rather than assuming 18.
  g722: Fix the QMF scaling
  r3d: don't set codec timebase.
  electronicarts: set timebase for tgv video.
  electronicarts: parse the framerate for cmv video.
  ogg: don't set codec timebase
  electronicarts: don't set codec timebase
  avs: don't set codec timebase
  wavpack: Fix an integer overflow
