Viewing an RTSP stream

I have a number of Foscam Fi2918w cameras that all stream fine using HTTP. I need to change one of them to use RTSP via VLC. I consistently get back an error that says only that it can’t open the stream (for example) cvlc ‘rtsp://IPADDRESS:88’ just produces:

00007f2c88001130] live555 demux error: Failed to connect with rtsp://192.168.254.18:88/

[00007f2c94000c80] main input error: VLC is unable to open the MRL ‘rtsp://192.168.254.18:88/’. Check the log for details.

Any ideas about what I’m doing wrong?
