      For ext-intra direcation intra modes:
      
      1. Use neighbor block modes to modify edge filtering strength
         Coding gain (lowres/midres/hdres):
           (8 keyframes)
           PSNR: -0.19 -0.22 -0.10
           SSIM: -0.29 -0.27 -0.13
      
      2. Use context-based cdf to code angle_delta syntax
           (8 keyframes)
           PSNR: -0.20 -0.24 -0.27
           SSIM: -0.29 -0.33 -0.37
      
      3. Filter corner sample:
           (8 keyframes)
           PSNR: -0.01 -0.02 -0.05
           SSIM: -0.03 -0.04 -0.05
      
      Combined Bd-rate improvement for 8 keyframes
           PSNR: -0.40 -0.47 -0.40
           SSIM: -0.57 -0.60 -0.51

      Add short_filter experiment · f02f8aef
      Zhijie Yang authored
      Reduce the motion interpolation filter taps for inter prediction
      blocks with widths or heights smaller than or equal to 4 to alleviate the memory
      bandwidth increase.

      Temporarily disable simple_bwd_adapt · c002bdf6
      Yaowu Xu authored
      This allows time to investiage the bug related to issue#917, adn the
      experiment should be re-enabled after a proper fix is in place for
      the issue.

      Find warped reference MV · 97d6a37e
      Yunqing Wang authored
      While finding the reference MV for a block, if one neighbouring block's
      motion mode is warped motion mode, instead of directly adding that
      block's MV to the candidate MV list, we use that neighbouring block's
      warped motion parameters to compute a MV for the center point of the
      current block, and then add that MV to the candidate MV list.
      
      Borg test result:
                   avg_psnr ovr_psnr ssim
      cam_lowres:  -0.507   -0.514  -0.685
      lowres:      -0.114   -0.122  -0.180
      
      The change is added under ext_warped_motion config flag.
