  "message": "Add speed feature to turn off global motion recode\n\nThis feature is turned on by default. There are big speedups\non certain sequences.\nEx. city_cif.y4m 20 frames goes from: 410ms -\u003e 234ms\n\nCoding efficiency loss is +0.21% on cam_lowres, and\n+0.14% on lowres.\n\nThe global motion recode loop is quite inefficient, and other ways\nto recover the loss  by better implementation of the strategy\nwithout a full recode will be explored next. But as of now the\ntrade off seems reasonable.\n\nThe reduced reference global motion search feature is also\nturned on by default. It gives a small speedup, but negligible\nloss in coding efficiency.\n\nSTATS_CHANGED expected.\n\nChange-Id: If7c971717af60c1c12cef8bc2ba44b3a651ea96a\n",
