I use rtp multicast this time and refer to this post, 'How to set up live streaming using a native RTP encoder with SDP file' http://www.wowza.com/forums/content.php?38. The problem is I can't define outgoing stream to the IP of my Wowza Media Server as the encoder is multicasting and the encoder doesn't support generating a SDP file. Is there any way I can let the Wowza Media Server catch the stream by checking the multicast IP pool? Thank you.
