I'm not sure what you mean with 'officially' here. Every symbol exported by
a shared library can be used by another program.
Even if only other av* libraries use the avpriv_* symbols they can't just be
removed, because that would break ABI compatibility between the old version
of the library using such a symbol with the new version of the other library
not exporting this symbol anymore.
Unrelated to any ABI or API problems, a use-case of mixing different
versions of the libraries strongly advised against ever using or a
distribution enabling such use, because its hardly ever tested, and
results may be rather unpredictable, especially with a lot of
applications sadly still using some of the API "incorrectly".
There shouldn't be any problem, as long as libraries with the same major
SOVERSION are ABI backward-compatible.
If there would be a problem, I would call it a (very strange) bug.
Have you ever heard of such a problem?
If you don't want different versions of the libraries used together, you
should either bundle all these libraries into a big one or bump all
major SOVERSIONs in every release. Neither of those make much sense, I
think.
Best regards,
Andreas
