"by this application i stream 2 streams from vivotek camera and screen share, and that works to."
Sorry, there is a typo in the readme at the bottom. Two lines publish one incoming stream to two multicast streams it should look like this:
# Incoming stream myStream will be published to multicast addresses:
In the above "myStream" is the incoming stream. In your case I think you should have:
Test that the multicast publish module is receiving the incoming stream and publishing the new streamname:
Use a text editor to open up the .sdp file in the folder /[Wowza]/applications/live1/sdp/. It should have the multicast address. To test that multicast is working, you should be able to open the multicast stream from another computer and play the stream. Copy the actual .sdp file over to the other computer, or make it available, on your webserver, then open it with a player that supports .sdp files.
