  "message": "Optimizing obmc rd decision by checking the real rd cost\n\nInstead of using model_rd_for_sb() to estimate the cost and make the\ndecision on bmc/obmc, we use super_block_yrd/uvrd() to calculate and\ncompare the real rd costs of bmc and obmc.\n\nAverage bit-rate reduction(%) of obmc experiment:\nderflr/derfhd/hevcmr/hevchd\n2.353/TBD/TBD/TBD\nBefore the optimization, the coding gain was:\n1.582/1.109/1.600/1.164\n\nNote: there is still some mysterious bug because that compared to\nthe previous version, the performance at low bit rate drops a lot.\n\nChange-Id: I8dbee04a272190f10516a3953c1ae690f8136766\n",
