      Replacing {VP9_COEF, MODE}_UPDATE_PROB with DIFF_UPDATE_PROB. · 4a0f9478
      Dmitry Kovalev authored
      Values of MODE_UPDATE_PROB and VP9_COEF_UPDATE_PROB are equal, so replacing
      them with one constant. Inlining appropriate arguments for functions:
        vp9_cond_prob_diff_update (encoder)
        vp9_diff_update_prob (decoder)

      Deprecate the use of PARTITION_INFO from encoder · 03fe08ca
      Jingning Han authored
      Use b_mode_info to store the inter prediction mode of sub8x8 block,
      in replacement of the use of partition_info. Remove redundant buffer
      update for partition_info. For bus_cif at 2000 kbps, this seem to make
      speed 0 about 1% faster.

      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.

      Scott LaVarnway authored
      mode_info_context was stored as a grid of MODE_INFO structs.
      The grid now constists of a pointer to a MODE_INFO struct and
      a "in the image" flag.  The MODE_INFO structs are now stored
      as a stream, 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).

      Adds a speed feature for fast 1-loop forw updates · e02dc84c
      Deb Mukherjee authored
      Incorporates a speed feature for fast forward updates of
      coefficients. This feature takes 3 values:
      0 - use standard 2-loop version
      1 - use a 1-loop version
      2 - use a 1-loop version with reduced updates
      
      Results: derfraw300 +0.007% (on speed 0) at feature value = 1
                          -0.160% (on speed 0) at feature value = 2
      
      There is substantial speed up at speeds 2 and above for low
      resolution sequences where the entropy updates are a big part
      of the overall computations.

      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.
