Once the mainloop run, all signal handlers will be
triggered. E.g. if you run a
UI, you can do the
gst_element_set_state (pipeline, GST_STATE_NULL);
call, when the user presses a button. If you do a
commandline application, you
have to handle that on your own.

You could try adding a glib IO channel connected to stdin to
the glib main loop:

b-IO-Channels.html

see g_io_add_watch().
