I am trying to play live feed (using FLVPlayback) and getting this error:

[COLOR=“Red”][COLOR=“Navy”]Error #2044: Unhandled AsyncErrorEvent:. text=Error #2095: flash.net.NetConnection was unable to invoke callback onFCSubscribe. error=ReferenceError: Error #1069: Property onFCSubscribe not found on fl.video.ConnectClient and there is no default value.

I have tried adding various NetStausListeners, AsyncErrorEvent, SecurityErrorEvent etc but no use. Is there any way to avoid this. I was thinking of changing the inbuilt ConnectClient class to include property “onFCSubscribe” but not sure how to go about that.Any ideas?
