I also configured my opnsense box for multicast streaming over VLANs some days ago. The goal was to make a DLNA server (minidlna) in one VLAN discoverable and available to clients in a different VLAN.
At first I tried using igmp-proxy. The problem is that it ignores site-local multicasting and therefore does not forward those packets upstream (see https://github.com/pali/igmpproxy/blob/d755b5b6327982434b87d631e089099dfd9a2ab4/src/igmp.c#L124).
After installing pimd it worked without having to configure anything. I tried to build the package myself but due to limited time ended up installing it from https://pkg.hardenedbsd.org/HardenedBSD/pkg/FreeBSD:11:amd64/All/pimd-2.3.2.txz.
Things to note:
It would be great if pimd would be made available as an official plugin since igmp-proxy seems not to be working for inter-VLAN service discovery (SSDP / DLNA etc.).

Things to note:
- pimd can be started with all interfaces disabled by default ("pimd -N")
- interfaces can be enabled selectively by modifying /usr/local/etc/pimd.conf (I only enabled the VLAN interfaces I want to be able to participate in multicasting)
