Ronald S. Bultje	726501a34e	vp9: add 32x32 idct AVX2 implementation. About 1.8x speedup compared to AVX version for full IDCT. Other sub-IDCT scenarios also see speedups.

Ivan Uskov	b4054100f6	Revert "Merge commit '3c53627ac17fc6bdea5029be57da1e03b32d265d'" This reverts commit `d30cf57a7b`, reversing changes made to `acc155ac55`. The commit `d30cf57a7b` provided irrelevant code complexity and decoding slowdown. But the main disadvantage of this commit is a decoder crash. So it should be reverted.

Chris Cunningham	d59820f6fe	libavformat/matroskadec: fix unsigned overflow to improve seeking When seeking a file where codec delay is greater than 0, the timecode can become negative after offsetting by the codec delay. Failing to cast to a signed int64 will cause the check against skip_to_timecode to evaluate true for these negative values. This breaks the "skip_to" seek mechanism.

Jan Sebechlebsky	8c997b3d3d	avcodec/mpeg4_unpack_bframes_bsf: Copy packet props mpeg4_unpack_bframes_bsf bitstream filters constructs resulting packet using av_packet_from_data() function. This function however modifies only buffer (data) and leaves other fields untouched, so the content of other fields of the output packet is undefined. It is working with old BSF API, since old API filters just data and the packet fields are copied in av_apply_bitstream_filters from input packet. This change fixes the behaviour for the new BSF API.
