As far as I know the only thing that needs integration with the
QEventLoop is the bus messages. On X11, if Qt is compiled with GLib
support enabled, it is possible to use the GStreamer API without doing
anything else, just like you would use it with GLib/GObject. On other
platforms (and X11 with GLib support disabled), you need to poll the
bus for messages from the Qt event loop.

You might be interested in QtGStreamer [1], which already has this
kind of integration with the Qt event loop. Note that this library is
still a work in progress and it has no compatibility promises yet.
