Hello now it seem to work.

Jean-Pierre you are right with the Multicast address range of

224.0.0.0 - 239.255.255.255

Some reserved Ranges are :

224.0.0.1: all Multicast-Systems
224.0.0.2: all Router
224.0.0.12: all DHCP-Server/Relays

So I tried different setting as I do not have a router in my system only a switch
I used now at the end.


Conf_AddrUDP=224.0.0.1
Conf_Port=9001
Conf_LocalIP=172.24.53.211

I set the VLC Player to:

udp://@224.0.0.1:9001

With this setting it works.

The other thing I mentioned was the .255 for UDP this is excepted by any device in the subnet as Multicast locally.
So in my case a UDP to address 172.24.53.255 will be accepted by all devices. Now other information must be check if a device should respond to that UDP packet.

So we might talk also about different things.
