    [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.
