      ncobmc_adapt_weight: Add bitstream syntax · 85a8f70c
      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

      Add encoder/decoder support for var-refs · 7b1ec7a9
      Zoe Liu authored
      Check the availability of the reference frames at the frame level at
      both encoder and decoder, and if a reference frame is not available
      for a specific video frame, remove the signaling of such reference
      frame info at the block level.
      
      This patch adds the consideration of the bit saving inside the RD
      optimization loop.

      Rework txfm_above and txfm_left context offset · 331662e9
      Jingning Han authored
      Make the txfm_above and txfm_left be processed in the unit of
      miniumum transform block size. Scale the transform block step
      size with respect to the mode_info step size.
