They are the IGMP messages sent to join the multicast group the server will
be sending to, which in this case seems to be 228.67.43.91.
On most decent (and properly configured) pieces of network hardware you have
to join the group in order to receive packets sent to the multicast address.
These messages are required for multicast, but not for unicast, so if you
configure your server to stream unicast these messages should not appear.
