      vp9_pred_mv(): misc fixes and optimizations · 9fd8abc5
      Yaowu Xu authored
      1. skip near if it is same as nearest
      2. correct rounding for converting mv to fullpel position
      3. update pred_mv_sad after new mv search.
      
      Overall .1%~.25% compression gains on rtc set for speed 5, 6, 7, 8.

      Revised rd adjustment for variance. · 7e234b92
      paulwilkins authored
      Revised adjustment for rd based on source complexity.
      Two cases:
      
      1) Bias against low variance intra predictors
      when the actual source variance is higher.
      
      2) When the source variance is very low to give a slight
      bias against predictors that might introduce false texture
      or features.
      
      The impact on metrics of this change across the test sets is
      small and mixed.
      
      derf -0.073%, -0.049%, -0.291%
      std hd -0.093%, -0.1%, -0.557%
      yt  +0.186%, +0.04%, - 0.074%
      ythd +0.625%, + 0.563%, +0.584%
      
      Medium to strong psycho-visual improvements in some
      problem clips.
      
      This feature and intra weight on GF group length now
      turned on by default.

      Experimental rd bias based on source vs recon variance. · 9a1ce7be
      paulwilkins authored
      This experiment biases the rd decision based on the impact
      a mode decision has on the relative spatial complexity of the
      reconstruction vs the source.
      
      The aim is to better retain a semblance of texture even if it
      is slightly misaligned / wrong, rather than use a simple rd
      measure that tends to favor use of a flat predictor if a perfect
      match can't be found.
      
      This improves the appearance of texture and visual quality
      on specific test clips but is hidden under a flag and currently
      off by default pending visual quality testing on a wider Yt set.
