      Contextual entropy coding of partition syntax · ff2b8aa2
      Jingning Han authored
      This commit enables selecting probability models for recursive block
      partition information syntax, depending on its above/left partition
      information, as well as the current block size. These conditional
      probability models are reasonably stationary and consistent across
      frames, hence the backward adaptive approach is used to maintain and
      update the contextual models.
      
      It achieves coding performance gains (on top of enabling rectangular
      block sizes):
      derf:   0.242%
      yt:     0.391%
      hd:     0.376%
      stdhd:  0.645%

      Convert coeff to per-plane MACROBLOCK data · 138ec38c
      John Koleszar authored
      This commit moves the coeff storage from the MACROBLOCK struct to its
      per-plane part. The next commit will remove the coeff member from the
      BLOCK structure so that it is consistently accessed per-plane.
      
      Also refactors vp9_sb_block_error_c and vp9_sb_uv_block_error_c to be
      variable subsampling aware.

      Move src_diff to per-plane MACROBLOCK data · cbd1315a
      John Koleszar authored
      First in a series of commits making certain MACROBLOCK members
      addressable per-plane. This commit also refactors the block subtraction
      functions vp9_subtract_b, vp9_subtract_sby_c, etc to be
      loops-over-planes and variable subsampling aware.

      Mv ref candidates cut to 2. · de80da39

      Further simplification of mvref search to return
      only the top two candidates. Distance weights removed
      as the test order reflects distance anyway.

      Simplification of MVref search. · 92e8a3f5
      Paul Wilkins authored
      As we are no longer able to sort the candidate
      mvrefs in both encoder and decode and given
      that the cost of explicit signalling has proved
      prohibitive, it no longer makes sense to find more
      than 2 candidates.
      
      This patch:
      
      Modifies and simplifies add_candidate_mv()
      
      Removes the forced addition of a 0 vector in the
      MAX_MV_REF_CANDIDATES-1 position (in preparation
      to reducing MAX_MV_REF_CANDIDATES to 2).
      
      Re-orders the addition of candidates slightly.
      
      This actually gives small gains (circa 0.2% on std-hd)
      
      A subsequent patch will remove NEW_MVREF experiment,
      reduce MAX_MV_REF_CANDIDATES to 2 and remove distance
      weights as these are implicit now in the order.

      Enable inter predictor for rectangular block size · 3ba9dd41
      Jingning Han authored
      Combine superblock inter predictors into a unified function that
      allows configurable block width and height. The inter predictions
      of block sizes smaller than 16x16 are handled differently. To be
      continued on merging them later.

      Make RD superblock mode search size-agnostic. · b4f6098e
      Ronald S. Bultje authored
      Merge various super_block_yrd and super_block_uvrd versions into one
      common function that works for all sizes. Make transform size selection
      size-agnostic also. This fixes a slight bug in the intra UV superblock
      code where it used the wrong transform size for txsz > 8x8, and stores
      the txsz selection for superblocks properly (instead of forgetting it).
      Lastly, it removes the trellis search that was done for 16x16 intra
      predictors, since trellis is relatively expensive and should thus only
      be done after RD mode selection.
      
      Gives basically identical results on derf (+0.009%).

      Merge sb32x32 and sb64x64 functions; allow for rectangular sizes. Code
      gives identical encoder results before and after. There are a few
      macros for rectangular block sizes under the sbsegment experiment; this
      experiment is not yet functional and should not yet be used.

      Clamp inferred motion vectors only · 12bf0796
      Jingning Han authored
      Clamp only the motion vectors inferred from neighboring reference
      macroblocks. The motion vectors obtained through motion search in
      NEWMV mode are constrained during the search process, which allows
      a relatively larger referencing region than the inferred mvs.
      Hence further clamping the best mv provided by the motion search may
      affect the efficacy of NEWMV mode.
      
      Synchronized the decoding process. The decoded mvs in NEWMV modes
      should be guaranteed to fit in the effective range. Put a mv range
      clamping function there for security purpose.
      
      This improves the coding performance of high motion sequences, e.g.,
      derf set:
      foreman 0.233%
      husky   0.175%
      icd     0.135%
      mother_daughter 0.337%
      pamphlet        0.561%
      
      stdhd set:
      blue_sky 0.408%
      city     0.455%
      also saw sunflower goes down by -0.469%.
