Application Element interaction

[Yogesh Tyagi]

 If I add a probe to src pad of my element and emit a signal from this
probe handler which will be received by the application.Upon receiving this
signal, application is supposed to do state change of this element.
Will it be a valid implementation? Does g_signal_emit or signal handler(in
application) run in pipeline context?

Thanks,
Yogesh
