      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.

      * Dering and clpf were merged into a single pass.
      * 32x32 and 128x128 filter block sizes for clpf were removed.
      * RDO for dering and clpf merged and improved:
        - "0" no longer required to be in the strength selection
        - Dering strength can now be 0, 1 or 2 bits per block

      EC_ADAPT: Perform backwards updates directly on CDFs. · 028b57f5
      Thomas Davies authored
      The initial CDF for each frame is stored in
      the frame context. CDFs for actual coding are
      stored in the tile structures, and these are
      what get adapted. The initial CDF is replaced
      by an average CDF derived from these tile CDFs.
      This is carried forward to future frames when
      backward adaptation is on.
      
      CDFs are no longer set from the 8 bit probabilities
      in backwards adaptation.
      
      For now, 8 bit probabilities are maintained for
      use in the encoder and for symbols which do not
      have a CDF.

      The variables robust and nodesync appear to represent the same concept.
      In order to simplify, they are merged into nodesync. This change does
      not alter the bitstream as this value is hard coded to 1.

      TILE_GROUPS: omit tile length from last tile in the frame. · a0de6d59
      Thomas Davies authored
      This change improves efficiency and means that tile groups
      cause negligible loss (+0.03% BDR) in the current default
      encoding configurations (1 tile group no matter how many tiles)
      with frame-based wrapping.
      
      In future, when wrapper formats support tile groups, lengths
      can be omitted from the last tile in every tile group.

      Disable the support of compound prediction modes for sub8x8 codking
      blocks. Make the rate-distortion optimizations process account for
      such constraints.
      
      With the use 2x2 chroma prediction block, this makes the wrost case
      number of inter predictors same as vp9. It affects the coding
      gains by 0.35% for lowres, 0.17% for midres, and 0.08% for hdres.
      
      The encoding speed is up by 10%.
