All things related to multicast

[Frank Fulchiero <>]

Hi all,
I know there have been other problems using QT Broadcaster and  
multicast relays in QTSS, so I came up with some documentation, but  
not sure it's totally correct.

If someone has a chance to scan it for inaccuracies, and/or also let  
me know if the multicast test (not optimized by any means) is working,  
I would appreciate it. The sdp file in QTSS/Movies can of course be  
created by other encoders.

We usually use Wirecast for live encoding, and I realize QT  
Broadcaster and Wirecast can both multicast without a relay, but  
wanted to test out the relays...and also placing the multicast sdp  
file on a regular web server.

Directions at

(I also would like to write up directions for creating the relay in  
the web admin, for DSS users)

Test stream at
http://136.244.12.62/mc/broadcaster-1mc.sdp
(use QT Player or VLC for client)

Thanks,
