It should work in principle, and we certainly want it to work, but
GStreamer is not an easy library to wrap and it's quite likely you'll be
hittingn bugs or missing features/annotations in both
gobject-introspection and GStreamer.

I think for the time being anything GStremaer/gi-related is still a bit
experimental.
