I will look into the *_FFLIBS variables. I figured it would be an OK
patch because of the swresample one recently added.

This would be preferred, or at least looking at the other patches first
as they are more complex. This is an issue which can be looked at after
all the other major issues are discussed, the main one being:
How avdevice and avformat interact going forward (see the v2 of the patch
which removes a bunch of register_all() functions for an explanation
of this issue).
