The important point is that you should never use or care about any of
the ff* or avpriv* symbols, unless you are actually developing inside
the libraries.
What happens to avpriv symbols is only a factor for in-between the av*
libraries, and of no concern to the users, since both are not part of
the official ABI/API.

Anyhow, the original question has been resolved, and there sadly are a
bunch of hacks that require a few ff symbols to be exported for use in
between libraries, but its already grown a lot less over the last few
versions, and hopefully can be removed at some point.
And just because its exported doesn't make it officially part of the
ABI, though.
