      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.

      Minor change in forward updates · a4d906c1
      Deb Mukherjee authored
      Removes the case of coding prob = 0 for forward updates, since that
      is not an allowed probability to code.
      Slightly improves efficiency but may not matter in practice.

      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

      Implement intra-coded frames · eac344ef

      Implements ability to signal and decode frames that are
      encoded using only intra coding modes. Only the decode
      side has been implemented here.

      TX_SIZE contexts simplification. · 17da2cab
      Deb Mukherjee authored
      Reduces TX_SIZE contexts to 2 for each kind. The code is
      cleaner and there is hardly any performance difference with
      more than two contexts.
      
      Results: almost neutral

      Uncompressed header: new encoding for frame size · 4053fde7
      Dmitry Kovalev authored
      For key frames everything is the same as before. For inter frames we try
      to reference last/golden/altref frame size. If there is no match then the
      actual size is encoded. Also we don't allow zero width and height anymore.

      Frame header changes to support intra_only frames · 07a5777b
      Adrian Grange authored
      Made changes to the frame header to write the sync
      code in the frame header for a non-displayable,
      intra-only frame.
      
      Extended reset_frame_context to 2-bits.

      Deb Mukherjee authored
      Adds coding of transform size within a frame by use of context
      of transform sizes selected in left and above blocks.
      
      Also incorporates code for generating stats.

      Refactors mbskip coding to be compatible with coding of the rest of

      the legacy code.

      Handle partition type coding of boundary blocks · 78b8190c
      Jingning Han authored
      The partition types of blocks sitting on the frame boundary are
      constrained by the block size and the position of each sub-block
      relative to the frame. Hence we use truncated probability models
      to handle the coding of such information.
