The 'watch' API is made especially with a GLib/Gtk main loop in mind. If
you don't run a main loop, you can use
gst_bus_have_pending()
gst_bus_pop()
gst_bus_timed_pop()
gst_bus_timed_pop_filtered()
whenever your application thread has some spare cycles to do so. If you
have a different kind of main loop or messaging system, you could
install a sync handler (called streaming threads), and signal your
application thread to check the bus for messages.
Alternatively, you could just start a thread of your own and do
gst_bus_timed_pop() in a loop with a -1 timeout. You can then send that
thread a custom application message to make it shutdown when needed.
(This solution means you might still need to be careful about
interacting with any other application threads though..)
