Note that you don't have to use a GMainLoop but you can also integrate
the GstBus with the Qt event loop:
  https://github.com/sdroege/gst-snippets/tree/master/qt5-eventloop

Nowadays (1.14 and newer) you can also get an fd from the GstBus which
always becomes readable when there is a message to read, which
potentially allows nicer integration but I didn't check that for Qt
yet.
