      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 It has been replaced
      by the new ec_multisymbol zero token handling.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.

      Fix encode/decode mismatches for supertx + delta-q · 3aec8d6c
      David Barker authored
      This fixes the following mismatch bugs:
      * At the bitstream level, the decoder would not read the delta_qindex
        information for supertx blocks, but the encoder always sent it,
        leading to the encoder and decoder becoming misaligned.
        The delta_qindex information is still required for supertx blocks,
        so change the decoder to read it.
      * In addition, the quantizer was not properly adjusted for supertx
        blocks at the decoder. We copy the quantizer setup code from
        non-supertx blocks.
      
      Since this does not change the encoder, it should not have any
      quality impact.

      Fix mismtach with ref-mv and ext-partition-types · ff59b6ac
      Debargha Mukherjee authored
      Change the list of search offsets searched when ext-partition-types
      is on for square block_sizes. This is because the VERTICAL_A and
      HORIZONTAL_A partitions are incompatible with the default list.

      Palette: Don't store tokens for pixels outside image boundary. · 56ba91bb
      Urvang Joshi authored
      If part of a block falls outside right and/or bottom image boundary,
      then only store tokens for the part of it within the boundary.
      
      Also, consider only the part of the block within the boundary when
      calculating the number of colors in the image, deciding the base
      colors for palette, RD calculation etc.
      
      The part of color map corresponding to pixels outside the image
      boundary is padded with color indices copied from same row/column.
      This behavior is similar to how pixels outside the boundary are padded.
      
      For screen_content set, this is improves compression performance by
      0.038 overall. One clip, in particular, has a significant gain of 0.8.
