FFmpeg's libavformat wants you to call a special function when you want to
use any networking protocols.
However it is not generally possible to know if your use of libavformat
will end up using networking protocols or not.
So what libavformat "wants" isn't really possible to do in a sensible
way and thus I have so far just ignored these printouts.
However I guess we would make it happy in the cases where
it is easy (like https:// URLs) and thus reduce the number
of cases where this spam appears.
