Gstreamer RTSP server: connection not established

[Mariem]

Hello, 

I am trying to stream a video between my target (which has Yocto installed)
and my PC (which has ubuntu) using a Logitech c920 HD Pro webcam. The usb
camera is plugged into the board.

In the server side (the board)  I have this:  
$gst-launch-1.0 -v v4l2src device=/dev/video8  !
video/x-raw,format=YUY2,width=1280,height=720 ! videoconvert ! queue !
x264enc ! rtph264pay ! udpsink host=127.0.0.1 port=5000

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
