  "message": "adjust sad per bit constants\n\nWhile investigating the effect of DC values on SAD and SSE in motion\nestimation, a side finding indicates the two table of constants need\nbe adjusted. The adjustment was done by multiplying old constants by\n90% with rounding. Also absorb the 1/2 scaling constant into the two\ntables. Refer to change Ifa285c3e for background of the 1/2 factor.\n\nCif set test showed a very small gain on all metric.\n\nChange-Id: I04333527a823371175dd46cb04a817e5b9a8b752\n",
