      Use CDFs to compute all intra mode related costs. · 693eedd1
      Nathan E. Egge authored
      When EC_ADAPT is enabled, this patch uses the adapted CDF after
       encoding the entire frame to compute the non-adapted costs that are
       used in RDO decision making when coding the following frame.
      Future patches will update these costs periodically while coding the
       frame to keep them in sync with the actual rates used when coding the
       symbols with the adapted CDF.

      Wei-Ting Lin authored
      Define the syntax and entropy coding templates for
      NCOBMC_ADAPT_WEIGHT. The actual values of the default
      probabilities and the index tree structure need to
      be fine tuned.
      
      In this experiment all mv's in a superblock are sent
      first as in the ncobmc case.

      Add new coding tool of ext-comp-refs · c082bbcb
      Zoe Liu authored
      The tool of ext-comp-refs adds the uni-directional compound reference
      prediction. In details, 3 pairs of uni-direcitonal compound references
      are added for the comp ref prediction:
      (LAST_FRAME, LAST2_FRAME),
      (LAST_FRAME, GOLDEN_FRAME), and
      (BWDREF_FRAME, ALTREF_FRAME).
      
      This new tool of ext-comp-refs will eventually overwrite
      one-side-compound and have the two coding tools to merge to one.
      
      It achieves -0.35 ~ -0.55% coding gains in BDRate, compared against
      AV1 baseline with the default experiments on, but without
      one-sided-compound. It achieves -0.2% ~ -0.3% coding gains when
      one-sided-compound is on. It achieves larger gains on higher
      resolution.

      Add encoder/decoder pipeline to support single ref comp modes · 85b66463
      Zoe Liu authored
      Now the single ref comp mode should work with WEDGE and
      COMPOUND_SEGMENT. For motion_var, the OBMC_CAUSAL mode uses the 2nd
      predictor if the neighboring block is single ref comp mode predicted.
      
      This patch removes the mode of SR_NEAREST_NEWMV and leaves four
      single ref comp modes in total:
      
      SR_NEAREST_NEARMV
      SR_NEAR_NEWMV
      SR_ZERO_NEWMV
      SR_NEW_NEWMV

      cb4x4: Move sub-4X4 TX sizes behind CONFIG_CHROMA_2X2. · fe67ed6a
      Timothy B. Terriberry authored
      cb4x4 itself should not require these sizes.
      
      This simplifies compatibility with other experiments, since we can
      first make them work with cb4x4 (which is now on by default), and
      then worry about chroma_2x2 (which is not) in separate steps.
      
      Encoder and decoder output should remain unchanged.

      Add CONFIG_INTERINTRA flags and reduce # of interintra modes to 4 · 4d26acb4
      Yue Chen authored
      Use CONFIG_INTERINTRA to properly separate interintra from the basic
      ext_inter experiment.
      When macro REDUCE_INTERINTRA_MODES is 1, only 4 ii modes are enabled
      so as to reduce the complexity overhead.
      (Right now the flag is off)

      [CFL] use CDF_SIZE macro · e21c0811
      Luc Trudeau authored
      EC_ADAPT stores the count at the last position. As such, the CDF_SIZE
      macro adds 1 to the array size. This resolves valgrind warnings about
      jumps on uninitialized variables.
