Can you be a little clearer here do you mean - doesn't work on that core 
or doesn't work on all cores ?

OK the 8916 to 8939 migration guide says HEVC decoder - encoder is not 
mentioned.

You can have a bitmask flag of whitelist or blacklist per core then - 
select which codecs are supported on which cores and then declare those 
to user-space.
