      change to properly account for coef scaling in unit tests · 95ee7f11
      Yaowu Xu authored
      The transform functions in experimental branch absorbed a scaling
      factor of 4 to allow quantization steps closer to unit quantizer.
      This commit added scaling code in between forward and inverse
      transform to properly account for the scaling factor.

      New Motion Reference Search · 2d60bee1
      Paul Wilkins authored
      Alternative strategy for finding a list of candidate motion
      vectors to use as reference values in mv coding and as
      nearest and near.
      
      Sort by sad in vp8_find_best_ref_mvs() rather than just
      pick the best. Allow 0,0 as a best ref option but not a
      nearest or near unless there are no alternatives.
      
      Encode/Decode verified on at least some clips.
      
      Some commented out experimental and stats code still in place.
      
      Gain over existing code averages about 1% on derf (alll metrics)
      with improvement on all clips. Other test results pending.
      
      The entropy coding of the mode (nearest/near etc) still
      depends upon and requires the old "findnear" code so
      this needs looking at and may provide room for further gains.

      Superblock coding. · 5d4cffb3
      Ronald S. Bultje authored
      This commit adds a pick_sb_mode() function which selects the best 32x32
      superblock coding mode. Then it selects the best per-MB modes, compares
      the two and encodes that in the bitstream.
      
      The bitstream coding is rather simplistic right now. At the SB level,
      we code a bit to indicate whether this block uses SB-coding (32x32
      prediction) or MB-coding (anything else), and then we follow with the
      actual modes. This could and should be modified in the future, but is
      omitted from this commit because it will likely involve reorganizing
      much more code rather than just adding SB coding, so it's better to let
      that be judged on its own merits.
      
      Gains on derf: about even, YT/HD: +0.75%, STD/HD: +1.5%.
