How to specify source address for source-specific multicasting in Gstreamer

I'm trying to set up a gstreamer1.0 client to receive a source specific multicast. It's clear how to set the group ip for the multicast, but I don't see any properties to set the source address. http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-good-plugins/html/gst-plugins-good-plugins-udpsrc.html

Solution

Just found it. Set the uri property in the following format: udp://172.22.200.54@239.130.110.108:10108'
