It's generally not necessary to send a new caps event when streams change if
the caps do not change, same goes for getting a new buffer pool. The old one
should continue to work as the stream format did not change.

Independent of that, requesting a new buffer pool would happen with the
ALLOCATION query and has nothing to do with the caps event.

Why exactly is it necessary in your case, what's the use case?
