Hi.
how to extract ONVIF-metadata from RTSP-source?

So, by teams 
*gst-launch-1.0 rtspsrc
location="rtsp://user:pass@xxx.xxx.xxx.xx:ppp/somesrc" debug=true !
fakesink*

received the SDP-package description
...
v=0
o=- 1188340656180883 1 IN IP4 192.168.0.4
s=Session streamed with GStreamer
i=rtsp-server
t=0 0
a=tool:GStreamer
a=type:broadcast
a=control:*
a=range:npt=now-
m=video 0 RTP/AVP 96
c=IN IP4 0.0.0.0
a=rtpmap:96 H264/90000

a=rtpmap:96 vnd.onvif.metadata/90000

Problem is executing the command
*gst-launch-1.0 rtspsrc
location="rtsp://user:pass@xxx.xxx.xxx.xx:ppp/somesrc"  ! application/x-rtp,
media=application ! fakesink dump=true -vvv*
causes an error:
