  "message": "Rework hash map for txk-sel\n\nThe txk-sel allows each transform block to select its own\ntransform kernel. Such locality enables one to store the selected\nRD cost including tx_type selection per transform block size.\nIt reduces the needed hash map size to 1 / 16 of what is needed\nwithout txk-sel.\n\nThis commit re-works the hash map RD cost fetch for txk-sel. Tested\non red_kayak_480p in speed 1, enabling txk-sel makes the encoding\nspeed 12% faster than the baseline without txk-sel on. Further\nenabling reduced hash map size gains speed 1 another 10%.\n\nChange-Id: I4a5d99d27e2a76b10e76c00a8178f692c95fdf13\n",
