[gst-devel] rtpbin + mpegtsmux

I'm trying to stream MPEG-TS data via RTP/RTCP using these pipelines:

Server:
   gst-launch -v gstrtpbin name=rtpbin v4l2src ! video/x-raw-yuv,width=720,height=480 !
     x264enc ! mpegtsmux ! rtpmp2tpay ! rtpbin.send_rtp_sink_0
     rtpbin.send_rtp_src_0 ! udpsink port=5000 host=192.168.1.101 ts-offset=0 name=vrtpsink
     rtpbin.send_rtcp_src_0 ! udpsink port=5001 host=192.168.1.101 sync=false async=false name=vrtcpsink
     udpsrc port=5005 name=vrtpsrc ! rtpbin.recv_rtcp_sink_0

Client:
   gst-launch -v gstrtpbin name=rtpbin latency=200
     udpsrc caps=application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)MP2T-ES port=5000 !
        rtpbin.recv_rtp_sink_0 rtpbin. ! rtpmp2tdepay ! mpegtsdemux name=demux ! ffdec_h264 ! xvimagesink demux.
     udpsrc port=5001 ! rtpbin.recv_rtcp_sink_0 rtpbin.send_rtcp_src_0 !
        udpsink port=5005 host=192.168.1.101 sync=false async=false

When the server starts up, I get these notices:

Sadly, even though the server is pumping out data, I don't see
anything at the client (my xvimagesink window never opens up)

Any ideas what I'm doing wrong or how to diagnose this?

Thanks

Note: I'm also a bit unsure how to write these pipelines if I want
to put audio data into the .TS container as well.  Any pointers
on this would be most helpful.
