      Macro to disable warped/obmc_causal with global motion · 19234cc2
      Sarah Parker authored
      Enabling SEPARATE_GLOBAL_MOTION will remove the ability for
      a block that uses zeromv with global motion to pick warped_causal
      or obmc_causal as the motion mode. When this is enabled there is:
      
      0.05% drop on lowres for global + warped enabled
      0.15% drop on midres for global + warped enabled
      
      0.12% drop on lowres with global + motion var enabled
      0.07% drop on midres with global + motion var enabled
      No performance change for global, warped, or motion var individually.

      Fix sub8x8 rd costing to include global motion prediction · b3ebed1c
      Sarah Parker authored
      One codepath originally skipped a function which forks between
      gm prediction and regular inter prediction. This change fixes this
      for both high bit depth and regular bit depth.

      Restrict the number of neighbors in obmc mode · 5329a2bf
      Yue Chen authored
      Enable obmc mode only when there are <= 2 left neighbors and <=2
      above neighbors. Also disable it when there is no overlappable
      neighbors.
      
      Gain in AWCY test: 1.60%, was 1.64% when there is no restriction

      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.

      Fix ext-inter + compound-segment + supertx · 426a997e
      David Barker authored
      Allow the above combination of experiments to work together
      correctly, fixing an encode/decode mismatch bug when they
      were all enabled.
      
      This change causes build_masked_compound(_highbd) to only
      ever be called if CONFIG_SUPERTX is off, so wrap these functions
      in an '#if !CONFIG_SUPERTX' block.

      Angie Chiang authored
      By turning on CONVOLVE_POST_ROUNDING, in the compound inter
      prediction mode, FILTER_BITS rounding is moved after the summation
      of two predictions.

      This uses a segmentation mask (which is temporarily computed arbitrarily)
      to blend predictors in compound prediction. The mask will be computed
      using a color segmentation in a followup patch.

      Improve rdopt decisions for ext-inter · ac37fa3d
      David Barker authored
      Relative to previous ext-inter:
      lowres: -0.177%
           or -0.029% (with USE_RECT_INTERINTRA = 0)
      
      * When predicting interintra modes, the previous code did not provide
        the intra predictor with the correct context during rdopt. Add an
        explicit 'ctx' parameter to the relevant functions, to provide this
        context.
        This fixes a nondeterminism bug, which was causing test failures in
        *EncoderThreadTest*
      
      * For rectangular blocks, build_intra_predictors_for_interintra needs
        to overwrite part of the context buffer in order to set up the
        correct context for intra prediction. We now restore the original
        contents afterwards.
      
      * Add a flag to enable/disable rectangular interintra prediction;
        disabling improves encoding speed but reduces BDRATE improvement.
