It appears that you cannot set up an encoder push and a multicast using WM9 Encoder and WMS 9 Enterprise Edition.

It's too bad. The scenario for this was from behind a corporate firewall, I would push the encoder to a Internet based server, which could take advantage of Multicast to broadcast to it's internal subnets.

Try this experiment.

Set up an encoder push session. Go to the server where you will find the Publishing Point now set up. In the properties for the Publishing Point, enable the Multicast Plug-in. Go back to the encoder and start it.

The server Publishing Point will not start and in my case, most of the time it deletes itself (disappears).

I was trying this programmatically and only realized my problem was that it won't even do it non-programmatically.

I think I may have a workaround by creating two publishing points, one the push and the other a multicast which sources from the push publishing point, but I haven't tried it yet. That's a lot more programming so if anyone has any comments in the meantime, feel free to.

Hi Wray,

In order to push from your encoder to server with
multicast enabled, you don't have to go to the server and
manually enable the multicast plug-in if you can
successfully establish an authenticated DCOM connection
between your encoder and the server. The encoder will try
and generate the announcement and enable multicast for you
through DCOM connection to the server.

The publishing point disappearing problem could be because
you might have selected "Auto Remove" option when you
specified the push distribution parameters. The encoder
will remove the publishing point from server once the
broadcast ends (or may be in your case, when it fails).
Please uncheck this option and see if it makes any
difference.

Hope this helps.

Thx,
Ravi
