      Removed bmi from blockd · 57f180b3
      Scott LaVarnway authored
      This originally was "Removed update_blockd_bmi()".  Now,
      this patch removed bmi from blockd and uses the bmi found
      in mode_info_context.  Eliminates unnecessary bmi copies between
      blockd and mode_info_context.

      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%

      Extension of segmentation to 8 segments. · 31ee193a
      Paul Wilkins authored
      Also some further simplification following removal
      of top node code.
      
      There is an issue in regards to the shared file vp8cx.h
      in regard to the roi_map as this interface assumes that
      there are only 4 segments. I have left the value here as
      4 for now meaning that the roi_map interface is broken
      for VP9.
      
      Note that this change would have been easier if I hadn't
      had to search for hard wire instances of the number 4
      and <= 3.

      make buid_inter_predictors block size agnostic (luma) · 4924934d
      John Koleszar authored
      This commit converts the luma versions of vp9_build_inter_predictors_sb
      to use a common function. Update the convolution functions to support
      block sizes larger than 16x16, and add a foreach_predicted_block walker.
      
      Next step will be to calculate the UV motion vector and implement SBUV,
      then fold in vp9_build_inter16x16_predictors_mb and SPLITMV.
      
      At the 16x16, 32x32, and 64x64 levels implemented in this commit, each
      plane is predicted with only a single call to vp9_build_inter_predictor.
      This is not yet called for SPLITMV. If the notion of SPLITMV/I8X8/I4X4
      goes away, then the prediction block walker can go away, since we'll
      always predict the whole bsize in a single step. Implemented using a
      block walker at this stage for SPLITMV, as a 4x4 "prediction block size"
      within the BLOCK_SIZE_MB16X16 macroblock. It would also support other
      rectangular sizes too, if the blocks smaller than 16x16 remain
      implemented as a SPLITMV-like thing. Just using 4x4 for now.
      
      There's also a potential to combine with the foreach_transformed_block
      walker if the logic for calculating the size of the subsampled
      transform is made more straightforward, perhaps as a consequence of
      supporing smaller macroblocks than 16x16. Will watch what happens there.

      Recursive partition syntax coding · 90a91cc6
      Jingning Han authored
      Enable recursive partition information coding from SB64X64 down to
      MB16X16. The bit-stream syntax is now supporting rectangular block
      sizes. It starts from SB64X64 and recursively describes the partition
      type of the current block. If the partition type is PARTITION_NONE,
      the block is coded as a single unit; if it is PARTITION_HORZ or
      PARTITION_VERT, the block is segmented into two independently coded
      rectangular units, with no further partition needed; otherwise, the
      block is segmented into 4 square blocks. i.e., PARTITION_SPLIT case,
      each can be potentially further partitioned.
      
      Forward adaptive probability modeling is used for the partition
      information coding, conditioned on the current block size.

      Optimize the scaling calculation · 148eb803
      Yunqing Wang authored
      In decoder, the scaling calculation, such as (mv * x_num / x_den),
      is fairly time-consuming. In this patch, we check if the scaling
      happens or not at frame level, and then decide which function to
      call to skip scaling calculation when no scaling is needed. Tests
      showed a 3% decoder performance gain.
