This one will need a
REAL PRO 
Primero, the stream is geo-blocked! I had to proxy to Spain, and only then was able to view the vid

Moreover, the final token is constantly changing, which leads me to believe you will eventually need to regex this baby

=====================================
I think only KSV and few others on this forum may be able to help!
I couldn't even record it using RTMPDumpHelper
Probably due ton the proxy!
Good Luck!
