rtsp-server source video from udpsrc

Hi all,

I use this pipeline for local video stream into my IP camera:

    v4l2src always-copy=FALSE !
    'video/x-raw-yuv,format=(fourcc)NV12,width=640,height=480,framerate=(fraction)30/1' ! 
    TIVidenc1 bitRate=6000000 encodingPreset=2 codecName=h264enc engineName=codecServer contiguousInputFrame=TRUE !
    rtph264pay pt=96 !
    udpsink host= port=5000

I want to capture this video with rtsp-server and send it via network.
This is the code:

  pipeline = g_strdup_printf("("
    " udpsrc uri=udp://"
    " caps=\"application/x-rtp,media=(string)video,encoding-name=(string)H264\" !"
    " queue min-threshold-time=0 max-size-buffers=0 max-size-bytes=0 max-size-time=0 !"
    " rtph264pay pt=96 name=pay0 )");
  gst_rtsp_media_factory_set_launch(GST_RTSP_MEDIA_FACTORY(factory), pipeline);

I launch this receiver pipeline on my pc:

  gst-launch rtspsrc location=rtsp:// ! rtph264depay ! ffdec_h264 ! xvimagesink

In my IPCam I lauch before the pipeline and then rtsp-server, or otherwise, but no
video is received from my pc.

I haven't found solution to using rtsp-server with udpsrc!

I think that the pipeline must be launch only when rtsp stream is request by client (pc), because
if I launch first pipeline and then rtsp-server, this second lost the header h264.

Any help!?!
