      Add av1_convolve_2d_facade · 7927a97d
      Angie Chiang authored
      When convolve_round is on, av1_convolve_2d_facade will be used for
      interpolation rather than av1_convolve. Will remove the experiment
      code of convolve_round experiment from av1_convolve in another CL.
      
      So far we use 4-bit rounding in the intermediate stage on top of using
      post rounding for compound mode after the last stage.
      
      This will give us roughly 0.45% gain on lowres , 0.39% on midres and
      roughly 0.6-0.7% on hdres
      Altogether, is 1.15% on lowresm, 0.74% on midres and roughly 1.7-1.8% on
      hdres
      
      Note that there no restriction usage of 12-tap filter in the CL.
      Adding that, we will lose roughly 0.1% again on lowres.

      ec_multisymbol: Split off new new_tokenset experiment · a9598cd6
      Alex Converse authored
      The new_tokenset experiment replaces the unconstrained tokenset with a
      multisymbol alphabet in an inventive way.
      
      Tested configurations:
      new_tokenset + ec_adapt, new_tokenset, ec_multisymbol

      palette: fix bug in float_comparer() · e7a9133c
      Joe Young authored
      This function is used by av1_remove_duplicates() to remove
      duplicate palette colors.

      ans: Remove some dead code. · e8b34bb1
      Alex Converse authored
      This was part of the old ans zero token handling. It has been replaced
      by the new ec_multisymbol zero token handling.

      Add the new experiment tag 'tripred' · 70ae8f09
      Zoe Liu authored
      This experiment implements the idea of the uniform tri-prediction,
      which adds a 3rd inter prediction on top of the existing compound
      inter bi-prediction. The final predictor for an inter-coded block is
      the average of the compound bi-predictor and the third predictor,
      which is indentified by a third reference frame and a third motion
      vector.
