How to play a live stream in VLC player?

Hi

I know how to display a live stream on a webpage but I do not know how to display it in players like VLC and others that support playing flash.

It all come down to that I don't know the address for the live streaming (to insert in the VLC player).

The address is: rtmp://mydomain123.com/live/ and the channel is "test".

I have tried inserting rtmp://mydomain123.com/live/test into the VLC player but it did not work.

Can you help?
