Sorry, for dvb-t I have used:

gst-launch-0.10 -m dvbsrc pids=201:202:204 adapter=0 ! mpegtsdemux name=demux0
demux0. ! queue max-size-bytes=0 max-size-buffers=0 max-size-time=0 !
ffdec_h264 ! xvimagesink demux0. ! queue max-size-bytes=0
max-size-buffers=0 max-size-time=0 ! flump3dec ! pulsesink

"sync=true"
