      [lv_map_multi] Simplified multisymbol BR coding · 7d01ab54
      Dake He authored
      Multisymbol BR coding is simplified as follows.
      1. Remove computation of level counts by using a template of size 8;
      2. Context is derived by using a template of size 3.
      3. lps and eob probabilities are trained.
      4. Share contexts between TX_16X16 and above.
      
      The number of probability values used in BR coding are reduced from 1152 to 378.

      Overwrite frame level skip mode flag if no usage · 8a5d3437
      Zoe Liu authored
      Add a block level usage flag for skip mode. If no block has chosen the
      skip mode, the frame level flag for skip mode will be set off.
      
      This patch also includes a small code cleanup, including the check on
      whether the best RD mode is aligned with skip mode, if yes, the best
      RD mode will be replaced by skip mode.
      
      This patch slightly improves the coding performance of ext-skip.
