      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%

      Incorporate flexible tx type and tx partition in RD scheme · 4b594d3d
      Jingning Han authored
      This commit hooks up the rate-distortion optimization system to
      fully exploit recursive transform block partition and multiple
      transform type. The compression performance of the two experiments
      largely adds up. For derf set, ext-tx provides additional 2.1%
      coding gains on top of the gains due to recursive transform block
      partition (0.69%).

      Ronald S. Bultje authored
      We only write EOSB tokens if we write tokens (i.e. not for skip blocks),
      and we write EOSB tokens per-plane instead of per block.

      vp10: skip unreachable cat6 token extrabits. · 3461e8ce
      Ronald S. Bultje authored
      We have historically added new bits to cat6 whenever we added a new
      transform size (or bitdepth, for that matter). However, we have
      always coded these new bits regardless of the actual transform size,
      which means that for smaller transforms, we code bits that cannot
      possibly be set. The coding (quality) impact of this is negligible,
      but the bigger issue is that this allows creating bitstreams with
      coefficient values that are nonsensible and can cause int overflows,
      which then de facto become part of the bitstream spec. By not coding
      these bits, we remove this possibility.
      
      See issue 1065.
