Multi UDP Mux can't works when remote also enables Multi UDP Mux #507
Description
Your environment.
- Version: v2.2.12
What did you do?
I wrote sample code to simulcast multi-udp-mux for both of local and remote, such as two sfu cascade and they both use one signal udp port. And it CANNOT work
sample code

What did you expect?
It should work
What happened?
I currently think the reason is current code only use remote address as key in map to save udpMuxedConn, but in this case, all of the remote address is same. But I haven't confirm whether the root cause is it or not.
func (m *UDPMuxDefault) registerConnForAddress(conn *udpMuxedConn, addr string) {
if m.IsClosed() {
return
}
m.addressMapMu.Lock()
defer m.addressMapMu.Unlock()
existing, ok := m.addressMap[addr]
if ok {
existing.removeAddress(addr)
}
m.addressMap[addr] = conn
m.params.Logger.Debugf("Registered %s for %s", addr, conn.params.Key)
}
