[ibr-dtn] Video Streaming issue

Hello, my video streaming from camera (axis 207) is not working. I'm using two alix3d3 and can see the streaming rtsp in source, but I cant get it in vlc on the receiver. On sender, I'm using

cvlc rtsp://192.168.1.4/mpeg4/media.3gp --sout=file/mp4:- | dtnstream -l 3600 -d dtn://node2.dtn/streamReceiver -s streamSource

and on receiver side

dtnstream -s streamReceiver | vlc

are any of these commands wrong? camera IP is 192.168.1.4
