      Replace High 4:4:4 profile lossless with High 4:4:4 Predictive. · a9e86d24
      Fiona Glaser authored 
      This improves lossless compression by about 4-25% depending on source.
The benefit is generally higher for intra-only compression.
Also add support for 8x8dct and i8x8 blocks in lossless mode; this improves compression very slightly.
In some rare cases 8x8dct can hurt compression in lossless mode, but its usually helpful, albeit marginally.
Note that 8x8dct is only available with CABAC as it is never useful with CAVLC.
High 4:4:4 Predictive replaced the previous profile in a 2007 revision to the H.264 standard.
The only known compliant decoder for this profile is the latest version of CoreAVC.
As I write this, JM does not actually correctly decode this profile.
Hopefully this lack of support will soon change with this commit, as x264 will be (to my knowledge) the first compliant encoder.

      Cache motion vectors in lowres lookahead · c299b7d8
      Fiona Glaser authored 
      This vastly speeds up b-adapt 2, especially at large bframes values.
This changes output because now MV prediction in lookahead only uses L0/L1 MVs, not bidir.  This isn't a problem, since the bidir prediction wasn't really correct to begin with, so the change in output is neither positive nor negative.
This also allowed the removal of some unnecessary memsets, which should also give a small speed boost.
Finally, this allows the use of the lowres motion vectors for predictors in some future patch.

      lowres_init asm · 04dc2536
      Loren Merritt authored 
      rounding is changed for asm convenience. this makes the c version slower, but there's no way around that if all the implementations are to have the same results.

      New threading method: · 7b4f6a1f
      Loren Merritt authored 
      Encode multiple frames in prallel instead of dividing each frame into slices.
Improves speed, and reduces the bitrate penalty of threading.

Side effects:
It is no longer possible to re-encode a frame, so threaded scenecut detection
must run in the pre-me pass, which is faster but less precise. 
It is now useful to use more threads than you have cpus. --threads=auto has
been updated to use cpus*1.5.
Minor changes to ratecontrol.

New options: --pre-scenecut, --mvrange-thread, --non-deterministic
