Wowza cannot read multicast stream (via SDP file) but VLC can

I am running into an issue where Wowza cannot pick up a multicast stream (shows no media is flowing through) for a given SDP file. The stream is originating from another machine in my network.

The same .SDP file can be played successfully using VLC.

Following is the SDP file:


o=- 1 9 IN IP4


i=H264 session of mnt-2530245144-stream1-high


c=IN IP4

t=0 0

m=video 5006/1 RTP/AVP 102

i=Video stream

c=IN IP4

a=fmtp:102 width=1920;height=1080;depth=0;framerate=0;fieldrate=0;


a=rtpmap:102 H264/90000
