How do you work out the props?

Thank you both.  Nothing seemed obviously wrong in the output when I increased the debug level.  However, when I ran wireshark, I got an unending list of "Destination unreachable (unreachable port)" ICMP packets for the destination port.

The weird part is that my firewall should not be blocking this.  I'm running Fedora 20 with the standard firewall setup, the first two entries of which are,

   -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
   -A INPUT -i lo -j ACCEPT

So all loopback connections should go through.

Anyone have any ideas?


Also, I'd like to look into RTSP but although I found a packet receiver
(rtspsrc)
with gst-inspect, I can't seem to figure out how to invoke the server.   
The
gstreamer-rtsp-server documentation only lists the library functions.   
Does it
have to be done via a program or can I create an RTSP stream with a command line?
