I use the module Multicast Publish as instructed. In the conf/multicastmap.txt I just left it empty. I teseted with VLC the following rtsp link
rtsp://[wowza-ip-address]:1935/edge/xxjjkshjou?multicastplay
VLC can stream it with no problem. My question is how do I know if this is multicast or unicast? Again I note that there is nothing in the file multicastmap.txt
Thanks
