Device should send packets like this:
11:06:02.782172 IP 192.168.1.238.5004 > 239.255.42.42.5004: UDP, length 1328
11:06:02.782542 IP 192.168.1.238.5004 > 239.255.42.42.5004: UDP, length 1328
11:06:02.782775 IP 192.168.1.238.5004 > 239.255.42.42.5004: UDP, length 1328
11:06:02.783042 IP 192.168.1.238.5004 > 239.255.42.42.5004: UDP, length 1328
Connect to stream when on same subnet:
vlc udp://@239.255.42.42:5004
you can use SOCAT to relay from multicast to a unicast stream:
SRC=239.255.42.42
SRCP=5004
IF=eth0
DST=192.168.0.2:1234
# command to relay multicast to unicast
socat -T 3 UDP4-RECV:$SRCP,bind=$SRC,ip-add-membership=$SRC:$IF,reuseaddr UDP4-SENDTO:$DST,ip-multicast-ttl=8
# then run vlc on 192.168.0.2
vlc udp://@:1234
# another useful tool for passing stream between vlans
