Goto a chaturbate room in your browser and then goto the tools menu (or whatever it is in whichever browser you use) and "view source". Search that for "password" and you will see it, something like
Code:
password: 'pbkdf2_sha256$10000$B7osw0jRC3Qb$ etc etc etc kSMBOHwjzZk\u003D',
You need to go through and put a ^ in front of all the $'s and replace the \u003D with a "=" (minus the quotes). Then put the resulting string (starting with pdkd and ending with =) in place of "anonymous" in the 4th parameter in the rtmpdump command string.
