This allows detecting issues in side data related code, same as what
framecrc does for before already for packet data itself.

I am against this patch. Checksumming side data is a fundamentally wrong
thing to do.
It, or something equivalent is neccessary for regression testing.
(and it was you who asked also for the tests i run to be part of
fate. But here you object to it)
You know, not checking side data is not checking it so differences would then
not be
detected allowing for unintended changes to be introduced (aka bugs)
You have seen how much code is needed to get hashing to work for all
targets with some types, so it does feel like it's not the right thing
to do. ffprobe (and f_sidedata) are what should be used for actual
integrity checks.
And i insist that disabling printing the size (or any information about
side data) from framecrc is needed for FATE tests, as we can't even use
it to hash actual packet data otherwise.
