There's no need to run a main loop for this. You can check for messages on the bus with functions like gst_bus_pop() gst_bus_timed_pop() etc. which will block or not block, depending on your circumstances. See here: http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstBus.html#gst-bus-timed-pop You should check for messages on the bus regularly. How often regularly is, is up to you really. Cheers -Tim
