      Remove i4x4_pred. · 1efa79d3
      Ronald S. Bultje authored
      It remains as a local define in rdopt.c so we can distinguish between
      split and non-split modes in the RD loop, but disappears outside that
      scope in the codec.

      Patch to remove implicit segmentation. · 1b103f25
      Paul Wilkins authored
      This patch removes the implicit segmentation
      experiment from the code base as the benefits
      were still unproven as of the bitstream deadline.

      Add intra_only and reset_frame_context flags · 9e5bb959
      Adrian Grange authored
      Added two flags to the frame header:
      
      intra_only:
      Signals that the frame is encoded using only INTRA
      coding modes.
      
      reset_frame_context:
      Indicates that the coding context specified
      in the frame header should be reset to default values before the
      frame is encoded/decoded.

      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.
      
      Results on derf300: -0.237%

      Merge 4x4 block level partition into codebase · 7ac5ac52
      Jingning Han authored
      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.

      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.

      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).

      There is nothing particularly special about this code bitstream wise.
      Its derivation is the word "sync" coded using 4x6bit alphabetic indices.

      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 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.

      Make framebuffer allocations according to the chroma subsamping

      on keyframes, etc.
