This is a bug, can you report it here?
https://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer

It should work with your syntax, and it also does after making the
#ifdef here also for Linux:
https://cgit.freedesktop.org/gstreamer/gst-plugins-good/tree/gst/udp/gstudpsrc.c#n953


So apparently for IPv6 multicast addresses you can't bind directly to
them. While for IPv4 multicast addresses, binding directly to them is
required to filter out any packets that are for other destinations than
that multicast address. I wonder how to do the filtering with IPv6.
Someone needs to research that :)
