Hi Hendrik,
two related questions:
1. Seems it's a generic code. Could we handle this in the av1dec.c?
2. For the current code, what's happened if frame A ref to B, B ref to C.
and both A, B has update_grain == 0.
Is that considered a valid bitstream? If so, then value inferring should
be done in either CBS (like it's done for segmentation and loop filter),
or in av1dec.c. Otherwise all the fields will be zero, same as is the
case right now.
thanks

When update_grain is zero, the parameters should be taken from a
reference frame instead.
