  "message": "Use more localized stats for ref frame candidate pruning\n\nFor the mode_pruning_based_on_two_pass_partition_search speed feature,\ncollect mode decision stats for every 32x32 block in the first pass of\nparition search pass, and use the stats to prune modes in the\ncorresponding regions.\n\nCurrently the pruning is only applied to reference frames; the pruning\nstrategy is to skip reference frames that have not been selected in the\nfirst parition search pass.\n\nThis only affects speed \u003e\u003d 1.\n\nCompression loss on lowres and midres(30 frames) is about 0.1%.\nEncoding speed gains on some cif sequences with QP \u003d 30:\ncheer_cif:        6.4%\ncity_cif:         9.4%\ncoastguard_cif:  16.3%\ncontainer_cif:    9.0%\ncrew_cif:        11.3%\naverage:         10.5%\n\nChange-Id: I31211f16cbe639d2230babc21870d7ac54ca9a89\n",
