Laurie,

I got this working on WireCast for Mac.  The difference in my config and yours is that I used the same mcast address for both video and audio. Like you, I used the specified video port 5434 and audio 5432.

Has anyone managed to get multicast streaming working directly from a  PC running Wirecast?  we are having no luck getting it working.  Any success stories or thoughts on what we are doing wrong would be appreciated.

Here's the message I just sent to VaraSoft support:

We have been unable to configure Wirecast to produce a multicast LAN-MPEG4 stream on a Windows XP machine which is connected to a multicast-capable network.  I have successfully generated a multicast test data stream on the machine using iperf
The broadcast settings are:
Encoder preset: LAN-MPEG4
Destination: Multicast
Video Address: 233.0.237.212
Video Port: 5434
Audio Address: 233.0.237.210
Audio Port: 5432
TTL: 75

After exporting the SDP file, we try to open it on another machine on the multicast enabled network using QuickTime and the movie windows shows "Connecting..." for a few seconds and then shows "Ready" but we do not get any audio or video.
What are we missing?

We are hoping to use Wirecast  from the North American Network Operators (NANOG) meeting in Brooklyn NY on Monday to send out a multicast feed from the meeting location - that is if we can get Wirecast working properly.

cheers
