      The new motion mode "NCOBMC_ADAPT_WEIGHT" cannot be used
      in the motion search loop as it requires all mvs from the

      Define the syntax and entropy coding templates for

      supertx: Read and write transforms with CDF in decode_partition · 580943a7
      Rupert Swarbrick authored
      Patch b1bedf5f converted the three writes in bitstream.c that
      specify an extended transform from using av1_write_token (encoded with
      probability trees) to aom_write_symbol (encoded with CDFs).
      
      That patch fixed up the two reads in decodemv.c but didn't fix up the
      corresponding read in decodeframe.c. This patch does so.
      
      The patch also fixes up a write of a (non-extended) transform when not
      CONFIG_EXT_TX and the corresponding read.

      Add chorma tilesize option in loop-restoration · 84f567c7
      Debargha Mukherjee authored
      Adds an option bit in the bitstream syntax to allow chroma to
      have restoration tilesize that is coupled to luma based on
      subsmapling of the color components.
      
      This is meant to ease encoder hardware implementation.

      cb4x4: Move sub-4X4 block sizes behind chroma flags. · 81ec2619
      Timothy B. Terriberry authored
      cb4x4 itself should not require these sizes.
      
      This simplifies compatibility with other experiments, since we can
      first make them work with cb4x4 (which is now on by default), and
      then worry about chroma_sub8x8 and chroma_2x2 (which is not) in
      separate steps.
      
      Encoder and decoder output should remain unchanged.

      ext_inter: Skip compound type probs. for small block sizes. · 4a81001b
      Timothy B. Terriberry authored
      When writing the compressed header, prob_diff_update() was called
      for compound_type_prob[] for every defined block size, even though
      luma never uses block sizes smaller than 4x4.
      
      This fixes is_any_masked_compound_used() and
      is_interinter_compound_used() to properly return 0 for chroma-only
      block sizes, and then uses these functions to guard the probability
      updates in write_compressed_header() and read_compressed_header(),
      the same way the actual compound type values are guarded in
      read_inter_block_mode_info() and pack_inter_mode_mvs().
