[vlc-devel] [PATCH] rtsp: change default to unpriviledged

[Ross Finlayson]

A RTSP server should be using either port 554 or port 8554, as those 
are the two port numbers defined by IANA for RTSP; see 
http://www.iana.org/assignments/port-numbers

Port 5544 probably should not be used, because it's not defined 
anywhere (as far as I can tell).

Of these two valid ports (554 and 8554), port 554 is preferred, if 
possible, because that is the default port for RTSP.  If that port is 
used, then the port number doesn't need to appear in "rtsp://" URLs 
that clients use.  OTOH, if port 8554 is used (e.g., because the 
server doesn't have OS permission to use 554), then it will need to 
appear in "rtsp://" URLs - e.g., 
"rtsp://foo.example.com:8554/streamName".

FYI, our (LIVE555) pre-built RTSP server application works by first 
trying to use port 554.  If that fails, then it tries to use 8554 
instead.
