I have a multicast stream containing six programs coming into my office over one single udp port. I am using ffmpeg to push the streams to wowza…
I am able to map the programs, and run multiple instances of ffmpeg using the same port without a port binding error by using the option ?reuse=1.
Now, my problem is that when I push these streams back out to our broadcast server, only one stream can be watched. It seems to be the last ffmpeg instance that I run is the one that is viewable. The other streams just dont show up.
How can I get wowza to accept all of the streams and play them successfully?
Thanks in advance!!

Try setting Application.xml /RTP /DatagramPortSharing to “true”

Hi. Thanks for your reply. Unfortunately, I have already tried doing that. I restarted wowza after making the change, and the result is the same.
