[Live-devel] live-devel Digest, Vol 157, Issue 1

[Weber, Patrick]

Thanks for the response. Is there a non-default way (via C++ API) to select the NIC/IP address?  My application may use multicast for other purposes (Web service discovery, for example), and I need to have it active on each NIC.

My application can have multiple NICs - how do I tell RTSPServer which IP address to use?

By default, the server uses the network interface that?s used for IP multicast routing - i.e., the one that has a route for 224.0.0.0/4.  (The reason for this is that it uses IP multicast to detect its own IP address.)

So, the easiest way to choose a particular network interface is to reconfigure your host so that it uses that network interface for IP multicast routing.  You should be able to do this by running (as root):
	route add 224.0.0.0/4 ip-address-for-that-nic
