Just came across a post
"It is if you start streams with StreamManager or StartupStreams.xml.
You can avoid that if you only have Flash RTMP clients, you can use StreamType "rtp-live", then you do not have to use StreamManager or StartUpStreams to start the stream. The first Flash RTMP client that plays the stream will start it and it will stop 60 seconds after the last one stops.
so can some one provide the steps to implement the "rtp-live" so the stream starts when the first user play the stream and stops when the last user stop playing the stream.
