Thought of this a few days and I don't like this. This would make the
whole office (well, the package where the gstreamer thingy is in)
dependent on qt5. (Yes, I know it's already the case for gtk3, but that
imho is not a that big issue.)

I could hack around it but that doesn't scale
- needs 3 builds of avmedia (gtk3, qt5, neither)
- would need dpkg-divert and this effectively means you cannot coinstall
  the -gtk3 and -qt5 plugin packages (and thus not even -gtk3 and
  -kde5).

Can't the qt5 (and gtk3) libraries not dynamically loaded in some way?

Regards,

Rene
