      Splitting partition_probs array into two arrays. · dde8069e
      Dmitry Kovalev authored
      We only update partition_probs for inter frames but they are constant
      for key frames. It is not necessary to have constants inside frame
      context and copy them every time. This change reduces FRAME_CONTEXT size
      by at least 48 bytes.

      Replacing {VP9_COEF, MODE}_UPDATE_PROB with DIFF_UPDATE_PROB. · 4a0f9478

      Values of MODE_UPDATE_PROB and VP9_COEF_UPDATE_PROB are equal, so replacing
      them with one constant. Inlining appropriate arguments for functions:

      Changing the order switchable filter enum constants. · 3f611555
      Dmitry Kovalev authored
      This changeset allows to remove vp9_switchable_interp and
      vp9_switchable_interp_map arrays and make code much clear. Actually we
      still have to use these mapping but only inside read_interp_filter_type and
      write_interp_filter_type functions.

      Removing kf_{y, uv}_mode_prob arrays from VP9Common. · f9f453ec
      Dmitry Kovalev authored
      These arrays have constant values (no any updates). Removing two
      corresponding memcpy calls. Making a little cleanup in vp9_entropymode.h
      as well: removing redundant 'extern' keyword and moving all function
      declarations at the end.

      New probs for filters/tx_size and a few others · a43ff153
      Deb Mukherjee authored
      * New probs for subpel filters/tx_count
      * Makes a change to not reset to defaults for the tx_size
      probs if an intermediate frame reverts to using a fixed tx_size.
      * A few updates to the parameters for backward adaptation for mode/mv
      * some cosmetic cleanups

      New intra mode and partitioning probabilities. · ad343687
      Ronald S. Bultje authored
      Split partition probabilities between keyframes and non-keyframes,
      since they are fairly different. Also have per-blocksize interframe
      y intramode probabilities, since these vary heavily between different
      blocksizes.
      
      Lastly, replace default probabilities for partitioning and intra modes
      with new ones generated from current codec. Replace counts with actual
      probabilities also.

      1. remove prediction mode conversion

      coded ever. It is determined by ref_frame and block partition

      Replace default counts with default probs. · 99c4b1ee
      Paul Wilkins authored
      Replace vp9_kf_default_bmode_counts structure with
      direct default probabilities. The probability structure is
      smaller and it removes the need to specify in the bitstream
      how to convert the counts to probabilities.
      
      Note that I have concerns still about the size and value of
      the large intra mode context. This may cause problems for
      HW but it also means we rely heavily on reverse update as
      forwards update of a structure this size is problematic. I
      intend to review this more generally in the next few days to
      see if we can come up with a competitive solution that does
      not rely on such a large context.
