If there is little unread data in the ByteIOContext buffer, this may lead to reducing the size of the ByteIOContext buffer to little more the probe data size. This can lead to suboptimal aviobuf behaviour, e.g. making some demuxers fail to do short seeks backwards (if the input isn't seekable).

This is a lot more reliable to get cmov rather than trying to trick gcc into generating it, useful since it's 2% faster overall. Patch by Eli Friedman <eli.friedman at gmail> Originally committed as revision 24471 to svn://svn.ffmpeg.org/ffmpeg/trunk

on the huffman tree, instead of traversing the tree in a while loop. Based on the similar optimization in libvpx's detokenize.c 10% faster at normal bitrates, and 30% faster for high-bitrate intra-only Originally committed as revision 24468 to svn://svn.ffmpeg.org/ffmpeg/trunk

Take shortcuts based on statistically common situations. Add 4-at-a-time idct_dc function (mmx and sse2) since rows of 4 DC-only DCT blocks are common. TODO: tie this more directly into the MB mode, since the DC-level transform is only used for non-splitmv blocks? Originally committed as revision 24452 to svn://svn.ffmpeg.org/ffmpeg/trunk

Don't prefetch reference frames that were used less than 1/32th of the time so far in the frame. This helps speed up to ~2% on videos that, in many frames, make near-zero (but not entirely zero) use of golden and/or alt-refs. This is a very common property of videos encoded by libvpx.

Prefetch all refs (including altref), but only if they've been used so far this frame. ~2.5% faster overall. TODO: Do something even smarter, like using how often each ref has been used so far, so that a couple blocks of a rarely-used ref don't force us to prefetch it.
