[Live-devel] Multicast over RTSP

[DJM-Avalesta]

Hi, 

My live555-based RTSP video server is not working for multicast streams
when accessed from VLC via an RTSP URL such as: 

rtsp://10.100.10.71:554/Stream0 

When I use wireshark to view the IGMP packets I notice that the
following line is missing from the Session Description protocol returned
to the caller: 

Session Attribute (a): source-filter: incl IN IP4 224.180.10.71
10.100.10.71 

Do I somehow have to enable IGMPv3 to get this to work? 

When I use an SDP file from VLC, it works perfectly, but for ONVIF use,
I need it to work purely from an RTSP URL. 

Best regards 

DaveM
