Yeah you missing something.

Use this...
Code:
set /p username= What is the username to record?
title %username%
rtmpdump [...]
For the records... first line prompts for the model name you want to record, the second one set the window title to the name of the model (not necessary but nice).
Beware that I did not repeat the full rmtpdump command line, you have to add that.

Yeah, something is wrong. I can't get a cam working in my browser, but saving it with rtmpdump works fine.
