    Optimizing obmc rd decision by checking the real rd cost · a614262e
    Yue Chen authored
    Instead of using model_rd_for_sb() to estimate the cost and make the
    decision on bmc/obmc, we use super_block_yrd/uvrd() to calculate and
    compare the real rd costs of bmc and obmc.
    Average bit-rate reduction(%) of obmc experiment:
    Before the optimization, the coding gain was:
    Note: there is still some mysterious bug because that compared to
    the previous version, the performance at low bit rate drops a lot.
