sorry, I mispaste the output. Here is the correct:
THe pipeline is :
gst-launch -v filesrc location=shake.mp4 ! qtdemux name=d \
d. ! { queue ! rtpmp4gpay ! udpsink port=5000 } \
d. ! { queue ! rtpmp4vpay ! udpsink port=5002 }
and the output is;
Setting pipeline to PAUSED ...

Pipeline is PREROLLING ...
There is really only one udpsink. What's problem?
