If you want to process bus messages in a specific thread context that's
not the main application thread, then I would recommend just using
gst_bus_(timed)_pop_(filtered)() for this, either blocking in a while
loop with a small timeout, or hooked into whatever other event/loop
mechanism there is already. You don't need to use a GMainLoop to get to
the bus messages.
