MiniDLNA is a lightweight DLNA/UPnP media server. The MiniDNLA daemon serves media files (music, pictures, and video) to clients on a network.

This describes the configuration options in /etc/config/minidlna.

This is just an initial dump of all the options I found, I am not certain about any other options or their actual meaning!

I just guessed the Type entries. — hcc23 2013/02/21 02:02
