Hi,
so if you do use the debug mode then you can see right at the top what the problem was.
If you execute the link as one string without to declare the playpath then rtmpdump does execute the paramters wrong (in that case) = (playpath / app / tcUrl).Just set the playpath start manually and set a second slash after app or before playpath and now it works or just separate the parameters (-r / -a / -y).So I think its not necessary to post some basics & verify checks of rtmpdump personally by PM.
