What you mean with shuting down all processes? As far as I know GST
knows only one process: the main process. When I'm outside the main
process should it not be the case that each call to gst_perform or
similar is conclusive, hence finishing up? So how would a finalization
listener work once you exit again the byte code? Similar how would
saving a snapshot work? There you have to also save the image and
somehow "exit" back into C++ land to shut down. Am I missing here something?
