I would like to send a multicast flow over our local network

It works perfectly when Wirecast and clients (QuickTime) are on the same subnet

But when Wirecast and clients are on 2 different subnet it fails
(Router OK other multicast flow get trough)

I have seen with WireShark that Wirecast send frame with TTL always at 1. So it's quite normal that router drops

Does anyone have an idea or get the same problem?
This is a limitation from Wirecast ? (so why we have a TTL field)


Thanks for your help


I use Wirecast 3.5.5 on windows XP 32 SP3

I'm looking into this for you.
Do you have a network log that might indicate what's happening?

As you can see bellow TTL value is always at 1.
( If i use wirecast --> VLC and VLC Multicast, there is no problem with TTL value VLC handle correctly.
vlc -vvv rtsp://193.48.90.102:7070/test.sdp --sout udp:239.50.50.10 --ttl 5)

You can easily reproduce and snif with wireshark

I'm not seeing the screenshot. Please do post the link again. It's pointing to what looks like a D drive on a system and not an http link.
