  "message": "Adaptive txfm size selection depending on residual sse/variance\n\nThis commit enables an adaptive transform size selection method\nfor speed -6. It uses largest transform size when the sse is more\nthan 4 times of variance, i.e., most energy is compacted in the\nDC coefficient. Otherwise, use the default TX_8X8. It improves\nthe compression efficiency for rtc set of speed -6 by 0.8%, no\nspeed change observed.\n\nChange-Id: Ie6ed1e728ff7bf88ebe940a60811361cdd19969c\n",
