  "message": "Speed up by dropping some ref frames in compound search\n\nRecord distortion for each single ref in rd. Rank according to their\ndistortions. Then in compound search, drop the combination of ref\nframes of the largest and second largest distortions\n\nThis patch shows neutral performance on google test using lowres\nwith 20 frame.\n\nLocal tests show ~5% speed up over baseline.\n\nChange-Id: I722fe66a0551f5f8a044c57c55caa74e46db7ee8\n",
