      Cleaning up vp9_mvref_common.c. · d689f2ad
      Dmitry Kovalev authored
      different_ref_found is always equal to one (if calculated) because
      ref_frame[0] != ref_frame[1] for each mi-block.

      Removed the reset of mode_info from previous frame · 896d79a5
      Yaowu Xu authored
      Prior to this commit, both encoder and decoder reset mode/mv info from
      previous frame in error resilient mode to ensure bitstreams are able to
      decode when there is loss of frame in decoder side. However, this is
      not necessary. This commit changed to remove the reset, so encoder can
      continue to use mode/mv/partition information from previously encoded
      frame without affecting decodeablilty under loss of frame.

      Define POSITION to differentiate from MV · 3cce4643
      Yaowu Xu authored
      MV struct was ussed to indicate the postition of a MI_BLOCK with row
      and col components. The expression was confusing, this commit added a
      new stucture "POSITION" with row and col component to better describe
      the position of a mi_block.

      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.

      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.

      This can only happen if partition is partly out-of-frame, in which
      case the referenced mv is either out-of-frame also (and thus has the
      same value as an already-read one), or it is actually uninitialized,
      in which case we don't want to use it.

      New inter mode context. · 6ff3eb16
      Paul Wilkins authored
      This patch creates a new inter mode contest that avoids
      a dependence on the reconstructed motion vectors from
      neighboring blocks. This was a change requested by
      a hardware vendor to improve decode performance.
      
      As part of this change I have also made some modifications
      to stats output code (under a flag) to allow accumulation of
      inter mode context flags over multiple clips
      
      Some further changes will be required to accommodate the
      deprecation of the split mv mode over the next few days.
      
      Performance as stands is around -0.25% on derf and
      std-hd but up on the YT and YT-HD sets. With further tuning
      or some adjustment to the context criteria it should be
      possible to make this change broadly neutral.
