Hi everybody,
Currently coding a C application that is sending video over the network
using MULTICAST, I am looking for a way to set on which network
interface the RTP stream should be sent.
I tried to use 'rtp://237.0.0.1:1234?localaddr=192.168.1.1' but it does
not work. After digging in the source code of the RTP protocol, it seems
that this option is not supported right now.
Thus I would like to know if I can access to the underlying socket in
order to apply IP_MULTICAST_IF using setsockopt (6.3:
https://www.tldp.org/HOWTO/Multicast-HOWTO-6.html)
Any clues of how to solve this issue programmatically?
Thanks,
