doPlay(url, this) help

[jinbao xu]

When I was viewing the medooze code, I read the rtmp protocol stack function:

void MultiConf::NetStream::doPlay(std::wstring& url, RTMPMediaStream::Listener* listener),

How does this function forward the data stream to the streaming end? 

Does it need to be associated with RTMPConnection? 

How is it connected? 

Thank you
