How to play a multicast stream?

Hi all,
I’m trying to create a layout to play a multicast stream like this src=“udp://@192.168.3.123:1234”

The stream is working fine in VLC player. I tried several embedded code but no one is working… Please find bellow what i’ve been tested.

Is there anybody who already have created a “multicast” widget ?

Cheers,
Philippe
