Propose the coding structure for GF Group of 16 to use the following multi-layer design: 1st Layer: Frame 0 and Frame 16 (ALTREF) 2nd Layer: Frame 8 (ALTREF2) 3rd Layer: Frame 4 and 12 (ALTREF2) 4th Layer: Frame 2, 6, 10, and 14 (BWDREF) 5th Layer: Frame 1, 3, 5, 7, 9, 11, 13, and 15 This CL implements the reference frame update for a GF group of 16 using a look-up table, which is different from the current implementation. The motivation behind is to try out various GF group coding structures simply through manipulating the look-up table, instead of making changes on swapping the reference indexes and associated flags throughout the codebase.
