  "message": "Define coding parameters for GF group of 16\n\nPropose the coding structure for GF Group of 16 to use the following\nmulti-layer design:\n  1st Layer: Frame 0 and Frame 16 (ALTREF)\n  2nd Layer: Frame 8 (ALTREF2)\n  3rd Layer: Frame 4 and 12 (ALTREF2)\n  4th Layer: Frame 2, 6, 10, and 14 (BWDREF)\n  5th Layer: Frame 1, 3, 5, 7, 9, 11, 13, and 15\n\nThis CL implements the reference frame update for a GF group of 16\nusing a look-up table, which is different from the current\nimplementation. The motivation behind is to try out various GF group\ncoding structures simply through manipulating the look-up table,\ninstead of making changes on swapping the reference indexes and\nassociated flags throughout the codebase.\n\nChange-Id: I823edae1c26263e0e0642a580685a25e81caa0a9\n",
