      Decoder's code cleanup. · 3231da0a
      Dmitry Kovalev authored
      Using vp9_set_pred_flag function instead of custom code, adding
      decode_tokens function which is now called from decode_atom,
      decode_sb_intra, and decode_sb.

      Make intra predictor reference buffer configurable · 861cb06c
      Jingning Han authored
      This commit enables configurable reference buffer pointer for intra
      predictor. This allows later removal of spatial dependency between
      blocks inside a 64x64 superblock in the rate-distortion optimization
      loop.

      Avoid inverse transform/recon without residual · a5657f2c
      John Koleszar authored
      Avoid calling decode_block, inverse transform/add in the block is
      a skip block for SBs smaller than 8x8 and intra-coded SBs.

      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.

      * Makes a change to not reset to defaults for the tx_size
      probs if an intermediate frame reverts to using a fixed tx_size.

      Reduces TX_SIZE contexts to 2 for each kind. The code is

      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.

      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.
