  "message": "Introduce one pass svm early termination speed feature.\n\nThis speed feature extracts regional data after rd_pick_partition\ntries none partition, and then uses a rd_weighted svm to decide whether\nto early terminate partition decisions.\n\nThis speed feature currently out-performs two_pass_partition_search in\nboth BDBR and time reduction. However, most of the performance gain\ncomes from low bitrate regime, so two_pass_partititon_search still\noutperforms at high bit-rate regime. Thus this speed feature is not on\nby default.\n\n                 | ONE PASS SVM | TWO PASS |\nBDBR             |    0.5310    |  0.6930  |\nTime Reduction 1 |    0.1080    |  0.0790  |\nTime Reduction 2 |    0.1268    |  0.1224  |\n\nAll metrics are calculated relative to one pass baseline. BDBR is\ncalculated on midres. Time reduction 1 is calculated over 15 midres clips\nat qp 35, 45, 55. Time reduction 2 is calculated over 5 midres clips at 6\ndiffernt bitrates from 75 to 8000.\n\nChange-Id: I640f5546b1eb3b212fcc6821e3311c4b13798ccf\n",
