I am new to Wowza and I am trying to utilize MediaCaster feature. In Wowza's user guide I read the following:

The MediaCaster system pulls a stream from a stream source and makes it available for streaming to the different player technologies supported by Wowza Media Server. This system works on demand—when the first request comes in for a given stream, a connection is made to the source stream and the stream is then made available to the player.

So, I setup DarwinStreamingServer to emulate live RTSP source and added the following entry to StartupStreams.xml:




Indeed I can watch rtsp://, but the system does not seem to work on demand. Moreover, in wireshark I am seeing that Wowza on startup will do DESCRIBE,SETUP,PLAY on the stream without any clients demanding the stream.

Why does it work different than described?
