In my project I was doing something similar. You can take a look at
the function which adjust caps for the scaler element here:
http://www.gitorious.org/veter/veter/blobs/master/src/vehicle/VideoSenderThread.cpp#line264
It assumes that there are scaler element named "qos-scaler" followed
by caps filter named "qos-caps" .

HTH,
Andrey.
