Dumping Rtmp streams

I have seen some posts on net about dumping rtmp streams. Usually  you need to record the traffic between you and the web page offering rtmp stream to find out the location of mp4 file and other things.
Here is a command line foo

rtmpdump -r "rtmp://server.hostname.app" -a "application" -y mp4:031cef05aa114ejr48krui846960d79a.mp4 -W http://pathtoplayer/xxxplayer.commercial.swf -f "WIN 11,5,502,135" -p http://web.site.referring -o output.mp4
