    The condition is still not actually too ideal i am affraid.
udpsink just pulls packets from it's peer as fast as it can and throw
it on the network. So you really need an element in your pipelines
which would timestamp the packets and make the udpsink wait for the
expiry of the timestamp before it throws it on the network. The
simplest and the most obvious solution is to put 'identity' element
before udpsink and use it's 'datarate' property. Moreover, AFAIK the
'queue' doesn't help in here at all so you probably don't want to use
