That's done (like quite a bit of other stuff) using gobject signals,
in this particular case the invalidate signal. You use
g_signal_connect (player, "invalidate", G_CALLBACK
(invalidate_handler), callback_data); and the invalidate_handler will
be called whenever something on the screen changed.

The other interesting signal is the notify signal, which is emitted
whenever a property changes. You should probably look at
swfdec-gtk/swfdec_gtk_widget.c:swfdec_gtk_widget_invalidate_cb to see
what's done there.
