      Remove redundant loop in ctx_reset · 98bc74ca
      Luc Trudeau authored
      Merges two consecutive loops that iterated over TX_SIZES. There's no
      impact to the bitstream. The 4 used as the termination threshold in the
      second loop is equivalent to TX_SIZES.

      Thomas Davies authored
      When creating the CDF head, do not use 8-bit probabilities
      to make the CDF tables, but load them directly.
      
      CDF tail values are created from the ONE_TOKEN relative
      probability as before.

      improving palette throughput · 33bcd117
      Fangwen Fu authored
      * code the palette color index using 45 wavefront
      * interleave the coeff and palette color index in
        transform block level
      * the above change does not change code efficiency
      
      Details: 
      The 45 wavefront scan allows to compute the ctx of
      the diagonal samples' indices  at the same time. 
      Interleaving palette indices and palette residual
      on a transform block basis means that the entropy
       decoding and further processing of the palette 
      residual is not delayed by the entropy decoding 
      of all the color indices of the palette encoded 
      block.

      Allow disabling the 8-bit (low-bitdepth) operating path. · 98378137
      Sebastien Alaiwan authored
      This allows compiling a codec using the same operating path (the generic
      "high-bitdepth" one), regardless of the profile of the input bitstream.
      For now, keep the 16-bit (generic) pixel operating path disabled by default.

      Add get_plane_type() helper function. · 005feb6b
      Luc Trudeau authored
      Adds the static inline function get_plane_type to convert a plane number
      to the corresponding PLANE_TYPE.
      
      There's no change to the bitstream, it only encapsulates the logic to
      get the PLANE_TYPE.

      Add chroma 2x2 block experiment · 31b6a4f9
      Jingning Han authored
      Support the use of 2x2 prediction and transform block size for
      chroma components. This experiment builds on top of cb4x4. It
      brings back the loss in performance gains due to 4x4 chroma
      component constrain. The coding gains for lowres are up from 1.5%
      to 2.5%.

      Change gm_get_motion_vector · 45390c18
      David Barker authored
      Since gm_get_motion_vector is trying to give a motion vector for
      "the frame as a whole", it makes more sense for it to calculate
      the motion of the *center* of the block rather than the top-left
      corner of the frame.
      
      In theory, this change should also help the encoder make better
      decisions on when to use global motion. It avoids an issue
      where, early in the frame, NEARESTMV looks like a good way to use
      the global motion vector *without* paying the rate cost applied
      to the first few global motion blocks in each frame. This seems
      to lead to a better overall result.

      Fix bottom ref condition for intra prediction in cb4x4 · f0179c3c
      Jingning Han authored
      Resolve a rare enc/dec mismatch issue triggered by the 4x4 chroma
      block size in sub8x8 block coding.
      
      To avoid using 2x2 chroma block size, it always uses the top-left
      4x4 luma block coding information to predict the 4x4 chroma block.
      The rest 3 4x4 luma blocks will be coded independently without
      coding the collocated chroma blocks.
      
      The compression performance gains are 1.45% for lowres set (down
      from 2.4% of the original cb4x4 design).
