AV1 hardware decoder needs entropy parameters to decode frames.
They are computed from various arrays defined in AV1 section
"9.4. Default CDF tables".

Add helpers functions to init, store and get these parameters.

Is 'GPL-2.0-only' correct?


In their proprietary MPP code rockchip claims the copyright but Nicolas notices
it originally comes from AOM.
The correct license shoud be BSD-2-Clause, I will fix that in v4.

Weird, this doesn't seem to be used. I would expect this to be static as well.

Same for (I think) all these non-static arrays above.

What's going on with that?


I thought I have remove all unused arrays but obviously I have miss some.
The original file contains all the arrays from AV1 specifications but the
hardware/driver don't need all of them.
That will be fix in v4.
