It depends how do you want to grab private stream.

If you pay for your private stream there is high likelihood rtmpsuck will get it if it can get free stream.

You will not get all parameters wirh rtmpsuck, so I would not pay them untill at least I can see all parameters.

If you want to go one step further and grab private stream for free,
I am certain you need to figure out how to get secure token, plus who knows how they may be encrypting -y ( playpath ) and that has to be looked at as well.
