My problem is the one discribed in this issue - https://github.com/OpenRTMFP/ArcusNode/issues/5
ArcusNode is dumping the same error for me when I try to stream video to client with RTMFP.
The streamer part is in this repository: https://github.com/JanisGruzis/RtmfpStreamer
The receiver part is in this repository: https://github.com/JanisGruzis/RtmfpVideoPlayer
Those are FDT ActionScript projects. As far as issue tells I should not use stream replication but what is that and how to avoid it in AS? Can I avoid it with NetStream class by configuring it somehow? As you can tell Im quite new to Flash world so maybe Im missing something.
Also, the tutorial I inspired from was the following, but that is probably for Adobe Cirrus. http://old.haxe.org/doc/flash/peer2peer
It seems that ArcusNode is no more maintained (last commit is from 2 years ago). You could try MonaServer which is a complete open source and lightweight server. It supports each features of RTMFP (object replication, NetStream, NetGroup...).
They are also some samples here : Mona Samples (source codes are here)
