It should be needed as when the input changes there might be a new 
possible caps to be negotiated in the pipeline. Are you having any issue 
with it? input-selector should automatically send the reconfigure and 
the elements involved will act on it if needed, there should be no need 
for the application to interfere.

What issues are you having?
