MiniDLNA plugin doesn't start

Can't get MiniDLNA to work in OMV 4 on my Raspberry Pi 3.
Installed through plugins page, no errors.
service minidlna status gives:

● minidlna.service - LSB: minidlna server

Any ideas?

I've googled libmmal_core.so, but haven't understood what it is or what it does (or in this case, doesn't do...).

Yes, that solved it! Thank you!

sudo apt-get install libraspberrypi0and then a reboot, and it works perfectly again.
