Enhancement layer level signaling in SVC test streams
It seems like some of the SVC streams have an issue with wrong level being signaled for enhancement layers.
For example, in both files with spatial scalability av1-1-b8-22-svc-L2T1.ivf and av1-1-b8-22-svc-L2T2.ivf the seq_level_idx[i] = 1 for all operating points meaning that the level is set to 2.1 for all operating points. However the MaxPicSize for level 2.1 is set to 278784 samples, which is exceeded when an enhancement layer with the resolution 1280x720 is played.
I suspect that the seq_level_idx[n] = 5 (level 3.1) needs to be set when n is the operating point of enhanced resolution.
I attach the analyzer headers dump for convenience. av1-1-b8-22-svc-L2T1_head.txt
