      Change above/left_context to use an 8x8 basis. · 2dbaa4f4
      Ronald S. Bultje authored
      Output changes slightly because of a minor bug in (at least) the sb32x16
      block2above tx16x16 tables that previously existed in vp9_blockd.c.

      Unify decode_sb for >16x16 in vp9_decodframe.c · d8a120c1
      John Koleszar authored
      First patch to make sb decoding based on the transform size. This patch
      is working for the sb modes, combining the parts of decode_mb that fit
      into this framework will come as a second patch.

      Merge two similar functions into one · bcf82cf5
      Yaowu Xu authored
      Function set_mb_row() and set_mb_col() do similar work and are always
      called together, this commit merged them into a single function for
      clarity and easy maintainence.  This was a TODO item.

      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.

      Simplify Segment Coding · c77aff12
      Paul Wilkins authored
      Remove top node optimization.
      The improvement this gives is not sufficient to justify
      the extra complexity.
