      Migrating SPLITMV_4X4 decoding into decode_atom · ce3a8a6e
      Jingning Han authored
      Separate the decoding process of 4x4 block based coding (both intra
      and inter) from decode_mb and move it into decode_atom_. This allows
      to further move the rest per 16x16 block decoding of decode_mb into
      decode_sb, and hence eventually deprecating decode_mb when SB8X8 is
      enabled.

      Separate I4X4_PRED coding from macroblock modules · 94191b5c
      Jingning Han authored
      Separate the functionality of I4X4_PRED from decode_mb. Use
      decode_atom_intra instead, to enable recursive partition of superblock
      down to 8x8.

      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.

      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.

      Enable rectangular support for comp inter-intra · a26c1edb
      Jingning Han authored
      This commit enables rectangular block prediction of compound
      inter-intra mode. It combines the mb/sb32/sb64 prediction functions
      into a unified version with configurable block width and height.
      This fixes the enc/dec mismatch of the codebase when
      comp-interintra-pred is enabled.

      First in a series of commits making certain MACROBLOCK members
      addressable per-plane. This commit also refactors the block subtraction

      loops-over-planes and variable subsampling aware.

      End of orientation zero group experiment · 70d9f116
      Deb Mukherjee authored
      Adds an experiment that codes an end-of-orientation symbol
      for every eligible zero encountered in scan order.
      
      This cleans out various other sub-experiments that were part
      of the origiinal patch, which will be later included if found
      useful.
      
      Results are slightly positive on all sets (0.1 - 0.2% range).

      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.
