      Remove redundant mode update in sub8x8 decoding · e85eaf6a
      Jingning Han authored
      The probability model used to code prediction mode is conditioned
      on the immediate above and left 8x8 blocks' prediction modes. When
      the above/left block is coded in sub8x8 mode, we use the prediction
      mode of the bottom-right sub8x8 block as the reference to generate
      the context.
      
      This commit moves the update of mbmi.mode out of the sub8x8 decoding
      loop, hence removing redundant update steps and keeping the bottom-
      right block's mode for the decoding process of next blocks.

      New mode_info_context storage -- undo revert · ac6093d1
      Scott LaVarnway authored
      mode_info_context was stored as a grid of MODE_INFO structs.
      The grid now constists of pointers to MODE_INFO structs.  The
      MODE_INFO structs are now stored as a stream (decoder only),
      eliminating unnecessary copies and is a little more cache
      friendly.

      For the test clips used, the decoder performance improved
      by ~4.3% (1080p) and ~9.7% (720p).
      
      Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p)
      and 5.9% (720p).

      make bsize requirement for SEG_LVL_SKIP explicit · 1ee66933
      Yaowu Xu authored
      The segment feature SEG_LVL_SKIP requires the prediction unit size
      to be at least BLOCK_8X8. This commit makes the requirement to be
      explicit. This is to prevent future encoder implementations from
      making wrong choices.

      Removing redundant calls to clamp_mv2. · cd2cc27a
      Dmitry Kovalev authored
      We could avoid calling clamp_mv2 because it has been already called
      inside vp9_find_best_ref_mvs function.

      Renaming in MB_MODE_INFO · 26fead7e
      Paul Wilkins authored
      The macro block mode info context originally contained an
      entry for each 16x16 macroblock. In VP9 each entry refers
      to an 8x8 region not a macro block, so the naming is misleading.
      
      This first stage clean up changes the names of 3 entries in the
      structure to remove the mb_ prefix.
      
      TODO clean up the nomenclature more widely in respect of
      mbmi and bmi.

      Renamed:

        MB_SEG_TREE_PROBS to SEG_TREE_PROBS
      
      The minimum unit for segmentation in the segment map
      is now 8x8 so it is misleading to use MB_ as macro-block
      traditionally refers to a 16x16 region.
