rtmpdump -r "rtmpe://edge4-b.stream.highwebmedia.com/live-edge" -W "http://chaturbate.com/static/flash/CBV_2p627.swf" -p "http://chaturbate.com/model_name/" -y mp4:%username%-sd-2c42ecd59c03850eaee04fd89924ee5c3a24b1a41b56711cf3c0176135569ad8" -o "CB\%username%-%date:~-4,4%%date:~-7,2%%date:~-10,2%%time:~-11,2%%time:~-8,2%%time:~-5,2%.flv" -C S:username -C S:%username% -C S:2.627 -C S:password -T "m9z#$dO0qe34Rxe@sMYxx%%" --live
