@Lilarcor -
Yes, the one piece of information you do need is the server's address, also known as the Host address. But this is usually fairly easy to find, by looking at the HTML source for the internet page which plays the media file that you are interested in.
Alternately, you can usually find it by running 'sniffer' software such as one of the programs
URL Snooper (a.k.a. Project URL Snooper) or
WinPcap or
Wireshark, that capture the packets passing through your internet connection - which you can then examine for the telltale
rtmpe:// string.
To tell rtmpdump that a stream is a live stream, you normally have to add the extra
switch
-live to the rtmpdump command line.
To stop recording a stream, simply close the Command window (a.k.a. "DOS Box") in which rtmpdump is running! Or simultaneously press the keyboard keys CTRL and BREAK.
But, certainly, if you want an easy life, rtmp streams on many websites can be captured using GUI front-ends for
rtmpdump -

I was just trying to demonstrate how to use rtmpdump on websites where the usual GUI front-end programs don't work.
