When the num_reorder_frames syntax element is not present, the value of
num_reorder_frames value shall be inferred to be equal to
When the max_dec_frame_buffering syntax element is not present, the
value of max_dec_frame_buffering shall be inferred to be equal to
MaxDpbSize is specified as a function of Level, which is not optional.
Or, since using a larger than necessary buffer will only waste memory
not change the result, you can ignore the chain of fallbacks and just
use 16 which is the max allowed value.
