* 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 ...
