Hay people! I need in your help!

Tell me please: Then i want using Multicast - programm show me this dialog...

UDP Multicast: Stream to multiple computers using multicast. Enter the IP address of the multicast group (in the 224.0.0.0 to 239.255.255.255 range).

The Question: What I must enter the group address?

My network begins since 192.168.55.10, but ends 192.168.55.255!
Help me please!

Hey,
Multicast is working a bit different to your noemal IP Protocol.

You can send ie. to 224.0.0.10 even if your IP is 192.168.99.55!
Your Switches and Router will transport the IP Trafic to all Hosts, that request it.
So, if you are sending on 224.0.0.10 Port 2000, all Clients that listen to this IP and Port will receive the Stream.

So feel free to choose a Multicast IP between 224.0.0.0 through 239.255.255.255

Here is a List of "Official" Multicast IP's...
(But inside your "Home" Network, you don't need to take care about the Reservations....)

Hope, that's anserwing your question?

I'm sorry, but I have one more question!

As other users will be connected to my multicast Stream?

What actions to them it is necessary will make in its VLC player?

Beforehand thank you!

Hi,

For other users to listen/view your multicast streams, all they have to do is to start VLC and enter your multicast address and port in the Network tab (windows UI) under the UDP/RTP Multicast fields.

The equivalent command line would be "vlc udp://@239.20.30.40:1233" for instance.

If the VLC viewer is not running in the same subnet perhaps the stream may have to go through routers. In this case I think the VLC streamer needs to specify the TTL (time to live) parameter to ensure proper delivery of the streams trough different numbers of routers. Check to doc to make sure.
