      Cleans up mbskip encoding · 869a39ba
      Deb Mukherjee authored
      Refactors mbskip coding to be compatible with coding of the rest of
      the symbols. Adds forward/backward adaptation and removes a lot of
      the legacy code.

      Code intra/inter, then comp/single, then the ref frame selection.
      Use contextualization for all steps. Don't code two past frames
      in comp pred mode.

      Balancing coef-tree to reduce bool decodes · b8b3f1a4
      Deb Mukherjee authored
      This patch changes the coefficient tree to move the EOB to below
      the ZERO node in order to save number of bool decodes.
      
      The advantages of moving EOB one step down as opposed to two steps down
      in the other parallel patch are: 1. The coef modeling based on
      the One-node becomes independent of the tree structure above it, and
      2. Fewer conext/counter increases are needed.
      
      The drawback is that the potential savings in bool decodes will be
      less, but assuming that 0s are much more predominant than 1's the
      potential savings is still likely to be substantial.

      Residual coding to cache energy class of tokens. · 88a4d4c5
      Sami Pietila authored
      Proposal for tuning the residual coding by changing how the context
      from previous tokens is calculated. Storing the energy class of previous
      tokens instead of the token itself eases the critical path of
      HW implementations.

      Merge 4x4 block level partition into codebase · 7ac5ac52

      Move 4x4/4x8/8x4 partition coding out of experimental list.
      
      This commit fixed the unit test failure issues. It also resolved
      the merge conflicts between 4x4 block level partition and iterative
      motion search for comp_inter_inter.

      Using 128 entry look up table for coef models · de4d682c
      Deb Mukherjee authored
      Reverts to using 128 bit LUT for the coef models rather than 48
      to ease hardware implementation.
      
      Also incorporates some cleanups including removing various
      hooks to support different lookup tables based on block_type and
      ref_type.

      Updating the model coef experiment · 39a90bc8
      Deb Mukherjee authored
      Cleans up the experiment. Actually uses reduced counts for backward
      updates, and reduced number of probabilities in the context.
      
      No change in bitstream when the experiment is on.
      
      Between expt on and off:
      derfraw300 is down only -0.062% (which is better than when expts
      were run previously).

      Enable recursive partition down to 4x4 · 1f26840f
      Jingning Han authored
      This commit allows the rate-distortion optimization recursion
      at encoder to go down to 4x4 block size. It deprecates the use
      of I4X4_PRED and SPLITMV syntax elements from bit-stream
      writing/reading. Will remove the unused probability models in
      the next patch.
      
      The partition type search and bit-stream are now capable of
      supporting the rectangular partition of 8x8 block, i.e., 8x4
      and 4x8. Need to revise the rate-distortion parts to get these
      two partition tested in the rd loop.

      Change to band calculation. · e5f71520
      Paul Wilkins authored
      Change band calculation back to simpler model based
      on the order in which coefficients are coded in scan order
      not the absolute coefficient positions.
      
      With the scatter scan experiment enabled the results were
      appear broadly neutral on derf (-0.028) but up a little on std-hd +0.134).
      
      Without the scatterscan experiment on the results were up derf as well.

      Framework changes in nzc to allow more flexibility · fe9b5143
      Deb Mukherjee authored
      The patch adds the flexibility to use standard EOB based coding
      on smaller block sizes and nzc based coding on larger blocksizes.
      The tx-sizes that use nzc based coding and those that use EOB based
      coding are controlled by a function get_nzc_used().
      By default, this function uses nzc based coding for 16x16 and 32x32
      transform blocks, which seem to bridge the performance gap
      substantially.
      
      All sets are now lower by 0.5% to 0.7%, as opposed to ~1.8% before.
