    [CFL] Custom block-level DC_PRED · f8164157
    Luc Trudeau authored
    Adds the CfL experiment flag and computes a block-level DC_PRED that is
    required by CfL in order to compute alpha_cb and alpha_cr.
    
    The rate-distorsion impact of computing DC_PRED at the prediction block level
    for chroma planes is rather small
