There is no need for qtdemux in this case. Just depayloaders and
decoders (for each stream).

Try:

gst-launch-0.10 -v rtspsrc location=rtsp://172.16.10.151:5544/cif !
rtph264depay ! h264dec ! fastoverlaysink

or even

gst-launch-0.10 -v uridecodebin uri=rtsp://172.16.10.151:5544/cif !
fastoverlaysink

(requires decoder element to have a rank and proper pad templates)

or even

gst-launch-0.10 -v playbin2 uri=rtsp://172.16.10.151:5544/cif
video-sink=fastoverlaysink

(depends a bit on your decoder + sink elements)
