The rtp and rtcp ports used in the rtspsrc filter are read from udpsrc elements
after setting them to the PAUSED state. The result is that sometimes, the RTP
port is odd. 

RFC3550 states that the RTP port SHOULD be even while the RTCP port SHOULD be
the next higher (odd) port number. Apple's Darwin Streaming server returns an
error if the RTP port is odd:
