Multicast stream is not working


#1

I have multicast video in group 239.1.1.1:1234, but it doesn’t work. How to fix it?

Hi,

Start with disabling firewall. It’s a most popular reason why Flussonic can’t ingest UDP traffic.
In Ubuntu you can do with the command:

iptables -F

Disable rp_filter if you have more then one physical interface.

sysctl -w 'net.ipv4.conf.all.rp_filter=0'

Actually, there are a lot of possible reasons, try to check the source with any player (e.g. VLC) and check that your server receives a multicast traffic. You can do it with tcpdump utility:

tcpdump host 239.255.1.1

(replace the host with a real address of multicast group)
