      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

      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.

      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.

      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.

      Fixes an issue with reducing branch cts in the encoder causing

      to it, and checked that results are identical to the parent
      of that patch.

      Added two flags to the frame header:

      reset_frame_context:
      Indicates that the coding context specified
      in the frame header should be reset to default values before the
      frame is encoded/decoded.

      Balancing coef-tree to reduce bool decodes · b8b3f1a4
      Deb Mukherjee authored
      This patch changes the coefficient tree to move the EOB to below
      the ZERO node in order to save number of bool decodes.
      
      The advantages of moving EOB one step down as opposed to two steps down
      in the other parallel patch are: 1. The coef modeling based on
      the One-node becomes independent of the tree structure above it, and
      2. Fewer conext/counter increases are needed.
      
      The drawback is that the potential savings in bool decodes will be
      less, but assuming that 0s are much more predominant than 1's the
      potential savings is still likely to be substantial.
