  You can pace (or throttle) the time at which the rtp packets are sent
by adjusting the outgoing timestamps of all buffers (i.e. the ones
coming out of the payloaders and going into the udpsinks). The packets
without timestamps will be sent as soon as they are received.

  Wim is also working on a way to throttle that based on buffer(list?)
duration also fwiw.
