Hi, I have tried various versions of this instruction.  
PLAY STREAM 1-10 udp://224.2.2:1001 without any luck.

I can play the stream with VLC on the same computer. This is a multicast stream of a IPTV channel.

Does anyone have any idea what I’m doing wrong?

You don’t need to add “STREAM” in the command for playing it; the server will automatically detect the source.  
The correct command is `PLAY 1-10 udp://224.2.2:1001`

Tried that as well and it didn’t work no error message just no stream.

ensure the server has network access and is allowed through your firewall.  
Try testing with a locally generated UDP stream using a tool like VLC and see if CasparCG can play that.

Thanks for the reply. I can play the stream on the same PC with VLC.

So that I understand you right: You can play the stream playing from Caspar with VLC? Or you can play a stream using VLC, without going trough Caspar?

Hi all, I have it working in the office but didn’t get it working on site. So nothing to do with Caspar, thank you all for your responses.
