If this is true, in general, then we can improve designs by removing
avpriv_* functions ...

looking at what we have as avprivs, in the tree, i think some of these
could be indeed usefull as public APIs. And we need to already keep them
compatible as they are exported as avpriv too, so making such changes does
indeed in some cases look like a good idea to me

There are some avprivs we have currently though that are quite specific
to format intgernals, i dont think that its always a flaw to use avpriv
functions thus

but i think we should evaluate each of the currently existing avpriv
functions and check if the API wouldnt be usefull to user applications.
And if it wouldnt be better to make it properly public
