That's strange; I wonder if it could be a firewall problem?  I.e., maybe you 
have a firewall - sitting between the proxy server and the back-end server - 
that is blocking UDP packets?  But that wouldn't explain the problem if the 
*only* difference between a working back-end server and a non-working back-end 
server is its port number.  But I suspect that - in reality - the RTSP port 
number is *not* the only difference between these two streams :-)

Does the "DESCRIBE" command - sent from the proxy server to the back-end server 
- still work successfully when the back-end server uses a port other than 554?

This suggests that you do, indeed, have a problem with receiving UDP (because 
VLC works by first requesting regular RTP-over-UDP streaming, and then - if it 
fails to receive packets within several seconds - requesting RTP-over-TCP 
streaming instead; that would explain the long delay).

To test this:

NOTE TO EVERYONE:  If you want to test a RTSP stream, you should do so first 
using our client applications: "testRTSPClient" and/or "openRTSP".  Only after 
you have gotten those to work should you then try using VLC.  (VLC is not our 
software.)

Try running "openRTSP -n rtsp://<ip address>:9494/axis-media/media.amp", and 
see whether it reports that "Data packets have begun arriving".  If it doesn't, 
then try again, but this time adding the "-t" option to "openRTSP" (to request 
RTP-over-TCP streaming).

If the "-t" option to "openRTSP" works, then the "LIVE555 Proxy Server" should 
also work (with this back-end stream) if you give it the "-t" option also.
