  "message": "Use tx_size 1 level down for transform type search\n\nThis addresses an inconsistency between the set used\nto decode the tx_type in the bitstream and the set used\nfor the tx_type search. Previously, the set used to\nread/write the tx_type was based on the smallest tx_size\nin the vartx partitioning, but the search uses a set\nbased on the largest possible tx_size. This patch\nchanges the tx_type search to use the transform type\nset associated with the tx_size 1 recursive level down from\nthe max square tx_size to make the search more consistent\nwith the bitstream syntax. If a tx_size is selected for an\ninvalid tx_type, DCT_DCT is used for that partition instead.\n\nThis patch also adds assertions to all exposed transform\nfunctions to ensure that no illegal transform type/size\ncombinations occur.\n\nThis currently gets a 0.1% drop in performance on lowres.\nThe drop is due to the reduction of the tx_types available\nfor 32x16 and 16x32 transform sizes. Before this patch,\n32x16 and 16x32 transforms were getting assigned a\nset of 12 tx_types, some of which we did not intend to\nsupport for these sizes.\n\nChange-Id: I44aca4876b261c345623cd04ad6235bca4532701\n",
