  "message": "Re-work rate-distortion optimization scheme for transform coding\n\nThis commit re-works the rate-distortion optimization scheme for\ntransform coding. It improves the overall compression performance.\nFor derf set, the ext-tx experiment provides 2.27% coding gains,\nand the new scheme that integrates multiple transform type selection\nand recursive transform block partitioning provides a total of 3.24%\ncoding gains.\n\nChange-Id: Ia1887c4c44b73dfb915d091d96660a99f09d5cc3\n",
