[Live-devel] multicast streams using same port

[PROMONET Michel]

                Hi Ross,

Googeling I found https://bugzilla.redhat.com/show_bug.cgi?id=231899 that is closed considering that it is not a bug.
Is it what you have in mind "Unfortunately at least some Linux kernel fanatics don't think it's a bug" ?
In fact I used since many years the workaround of bind the socket to the multicast group.

I tried on different kernel and used, something like a 3.4.x, the behaviour is the same.

Regards,

            Michel.

Yes, I read all that, and the sense I got from it is, Linux works one way, everything else works another way.  Thus my suggestion for a Linux-specific ifdef wrapping the bind() call.

Yes, but I also recall someone reporting that they tried this, but it didn't work for them (on Linux); apparently when they did this, they stopped receiving packets at all.

But if people want to try this themselves, then they're welcome to.  They probably don't even need to modify the "groupsock" code; instead, they could call "bind()" on the multicast address in their application code, immediately after they've created a "Groupsock" object.
