      Palette code: add comments and rename some variables. · 23a61117
      Urvang Joshi authored
      - Added comments for some tables and #defines for clarity.
      - Renamed some variables to ensure we use "color_index" instead of
      "color" for palette color index related variables.

      Add unpoison_partition_ctx experiment · 55c6bdeb
      Alex Converse authored
      At the edges of the picture only a subset of partitions are legal. Add
      new contexts for these borders so they don't distort the probabilities of
      the interior of the image where all partitions are legal.
      
      Only include one context for each block size of each border direction
      because so few blocks fall into these contexts to begin with.

      Add intra-interp experiment flag · eda3d764
      hui su authored
      intra-interp experiment allows intra prediction to use different
      interpolation filters. It was part of the ext-intra in the nextgenv2
      branch.

      Add 2x2 block unit syntax · f1702dde
      Jingning Han authored
      Add 2x2 block size syntax to the codec system. It prepares for the
      4x4 coding block unit for 420 format. This change retains the same
      coding statistics.

      Code cleanup: mainly rd_pick_partition and methods called from there. · 52648448
      Urvang Joshi authored
      - Const correctness
      - Refactoring
      - Make variables local when possible etc
      - Remove -Wcast-qual to allow explicitly casting away const.
      
      Cherry-picked from aomedia/master: c27fcccc
      And then a number of more const correctness changes to make sure other
      experiments build OK.

      Wrap palette code inside CONFIG_PALETTE flag. · b100db7c
      Urvang Joshi authored
      This flag was already added to aomedia/master, so bringing it back to
      webm/nextgenv2, as part of an effort to get the two codebases in sync.

      Enable tile-adaptive restoration · 5cd2ab95
      Debargha Mukherjee authored
      Includes a major refactoring/enhancement to support
      tile-adaptive switchable restoration. The framework can be
      readily extended to add more restoration schemes in the
      future. Also includes various cleanups and fixes.
      
      Specifically the framework allows restoration to be conducted
      on tiles such that each tile can be either left unrestored, or
      use bilateral or wiener filtering.
      
      There is a modest improvemnt in coding efficiency (0.1 - 0.2%).
      
      Further enhancements will be added subsequently to improve coding
      efficiency and complexity.

      Insert extra ARFs' in a gf group · 41d5d52d
      Wei-ting Lin authored
      Insert multiple arfs in a gf group to emulate multi-layer backward
      reference frames structure. At maximum, two extra ARF's are inserted
      in a gf group.
      
      It improves the RD performance by 0.317% in Avg in lowres dataset.
