      Super transform - ported from nextgen branch · 3787b174
      Debargha Mukherjee authored
      Various additional changes were made to make the experiment
      compatible with misc_fixes.
      
      derflr: +0.979%
      hevcmr: +0.865%
      
      Speed-wise with --enable-supertx the encoder is only about 10%
      slower than without. Decoding impact is about 30% slowdown.
      
      Note this does not work with ext-tx or var-tx yet. That is
      a TODO.

      Restore the flexibility for the new 3 references · ec36a2b0
      Zoe Liu authored
      For the experiment of EXT_REFS, removed the previous special handling
      on the new last 3 references, i.e. LAST2_FRAME, LAST3_FRAME, and
      LAST4_FRAME, at the decoder, so that these new last references are
      treated the same way as the other 3 references (LAST_FRAME,
      GOLDEN_FRAME, and ALTREF_FRAME). Encoder changes have been made
      accordingly to realize this flexibility.

      Fix a enc/dec mismatch under CONFIG_MISC_FIXES · c7101830
      Yaowu Xu authored
      The culprit is on the decode side xd->lossless[i] setup was in wrong
      location where segment features are not yet decoded.
      
      Also on the encoder side, transform mode was not set consistently
      between when tx_mode is selected and how tx_mode is enforced in
      tx size selection.

      Reduce transform options for ext-tx experiment · 56ab215d
      Debargha Mukherjee authored
      Reduces the transform optons for INTRA as well as INTER when
      transform size is 16x16 to not use any of the DSTs.
      Thus, a total of 10 options are used for 16x16, while 4x4
      and 8x8 still uses 17 options.
      
      derflr/hevchd actually improves a little, while hevcmr drops
      a little.
      
      About 10% speed improvement.

      New interpolation experiment · 85514c40
      Debargha Mukherjee authored
      Adds a new interpolation experiment.
      
      Improves entropy coding to send the filter type only if
      the motion vectors have subpel components.
      Adds one new 8-tap smooth filter, and tweaks the others.
      
      derflr: +0.695%
      hevcmr: +0.305%
      
      About 5% encode slowdown. No visible impact for decoding.
      
      Also makes the interpolation framework flexible to support both
      strictly interpolating filters as well as non-interpolating
      filters that filter integer offsets. This is mainly for
      further experimentation and if not found useful the code will
      be removed.

      ext-intra experiment · be3559ba
      hui su authored
      Currently there are two parts in this experiment: extra directional intra
      prediction modes and the filter intra modes migrated from the nextgen branch.
      
      Several macros are defined in "blockd.h" to provide controls of the experiment
      settings. Setting "DR_ONLY" as 1 (default is 0) means we only use directional
      modes, and skip the filter-intra modes; "EXT_INTRA_ANGLES" (default is 128)
      defines the number of different angles we want to support; setting
      "ANGLE_FAST_SEARCH" as 1 (default is 1) means we use fast sub-optimal search
      for the best prediction angle, instead of exhaustive search. The fast search
      is about 6 times faster than the exhaustive search, while preserving about
      60% of the coding gains.
      
      With extra directional prediction modes (fast search), we observe the following
      code gains (number in parentheses is for all-key-frame setting):
      derflr +0.42%  (+1.79%)
      hevclr +0.78%  (+2.19%)
      hevcmr +1.20%  (+3.49%)
      stdhd  +0.56%
      Speed-wise, about 110% slower for key frames, and 30% slower overall.
      
      The gains of filter intra modes mostly add up with the gains of directional
      modes. The overall coding gain of this experiment:
      derflr +0.94%
      hevclr +1.46%
      hevcmr +1.94%
      stdhd  +1.58%

      This commit makes the coefficient token packtization process account
      for variable transform block sizes supported in a single processing
      block. It fixes an enc/dec mismatch issue when var-tx, ext-tx, and
      misc-fixes experiments are all turned on.

      This has various benefits:
      - simplify implementations because we don't have to switch between
        multiple probability tables depending on frametype
      - allows fw subexp and bw adaptivity for partitions/uvmode in keyframes

      vp10: make segmentation probs use generic probability model. · 6e5a1165

      Locate them (code-wise) in frame_context, and have them be updated

      See issue 1040 point 1.
      
      TODOs:
      - real-world default probabilities
      - why is counts sometimes NULL in the decoder? Does that mean bw
        adaptivity updates only work on some frames? (I haven't looked
        very closely yet, maybe this is a red herring.)
