      Add 8-tap interpolation filter options for intra prediction · 3b1c7668
      hui su authored
      BD-rate performance improvement (on top of ext-intra):
      derflr  0.22%
      hevclr  0.36%
      hevcmr  0.48%
      hevchr  0.37%
      stdhd   0.19%
      
      Average speed impact on some derf clips is about 40% slower (on
      top of ext-intra). Speed improvment is a to-do.

      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%

      vp10: reimplement d45/4x4 to match vp8 instead of vp9. · 62a15795
      Ronald S. Bultje authored
      This is more a proof of concept than anything else. The problem here
      isn't so much how to code it, but rather where to place the resulting
      code. All intrapred DSP code lives in vpx_dsp, so do we want the vp10
      specific intra pred functions to live there, or in vp10/?
      
      See issue 1015.

      Code refactor on InterpKernel · 7186a2dd
      Zoe Liu authored
      It in essence refactors the code for both the interpolation
      filtering and the convolution. This change includes the moving
      of all the files as well as the changing of the code from vp9_
      prefix to vpx_ prefix accordingly, for underneath architectures:
      (1) x86;
      (2) arm/neon; and
      (3) mips/msa.
      The work on mips/drsp2 will be done in a separate change list.

      vp9_reconintra: simplify d63_predictor · 7012ba63
      James Zern authored
      calculate the averages needed for even and odd rows once; this removes a
      conditional from the inner loop
      the final average calculated currently relies on above[] being extended,
      it could be reduced to use
      above[block_size - 2] + 3 * above[block_size - 1]
