      As intra coded blocks are always decoded using decode_sb_intra(), this
      commmit removed the code no longer in use.

      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.

      changes intra coding to be based on txfm block · 8ba92a0b
      Yaowu Xu authored
      This commit changed the encoding and decoding of intra blocks to be
      based on transform block. In each prediction block, the intra coding
      iterates thorough each transform block based on raster scan order.
      
      This commit also fixed a bug in D135 prediction code.
      
      TODO next:
      The RD mode/txfm_size selection should take this into account when
      computing RD values.

      This commit allows the rate-distortion optimization of intra coding
      capable of supporting 8x4 and 4x8 partition settings.
      
      It enables the entropy coding of intra modes in key frame using a
      unified contextual probability model conditioned on its above/left
      prediction modes.

      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 bit-stream support to 8x4 and 4x8 partition · 810b612c
      Jingning Han authored
      The recursive partition type search is enabled down to 4x4, 4x8 and
      8x4, followed by the corresponding rate-distortion optimization for
      the per-partition encoding mode decisions.
      
      The bit-stream writing/reading synchronized in supporting the
      rectangular partition of 8x8 block.
      
      This provides above 1% coding performance gains on derf.
      
      To do next:
      1. re-design the rate-distortion loop for inter prediction below 8x8.
      2. re-design the rate-distortion loop for intra prediction below 4x4.
      3. make the loop-filter aware of rectangular partition of 8x8 block.
      4. clean the unused probability models.
      5. update default probability values.

      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 band calculation back to simpler model based

      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.
