I use a custom tool what can read the rtmp data in realtime and there I can execute it also directly before stream is loaded in browser.

So you could try to use the rtmpsrv-vlc but this dosen't work for your site.On the other hand you can patch your rtmpsuck file to execute rtmpdump with actually obtained rtmpdatas (instead to write a output file) so this should work too.Maybe anyone here can compile a version for you what can do this so I just patch or write new codes pieces by myself in debugger (OllyDBG) only.

But a better solution would be if anyone writes a script for your site (similar as WeebTV script by KSV) to read the app hash.
