I was looking for a solution to play video on my vr headset ($3) Samsung 8 in some viewer, aka the cardboard vr. First I thought that I would just view them over the network, but my rooted chosen ROM (Linage 17) doesn’t support smb from boot, so no fstab mapping can be done leaving me with a hacky file browse and view by another app solution. Then by chance playing with my TV and trying to watch films on the computer I finally found a use for a UPNP/DLNA Server. I found also my VR apps that any for of networking found the uPNP/DLNA server no problem, not smb loging on etc, sweet! Looking at the Windows uPNP offering I found none, for free or paid for, they could not make a custom menu from meta data tags. So Linux… Gerbera free and claimed to be able to do this so I had a go. A bit of hack trial and error later I got it going how I wanted with a sort of 2 level keyword search and reading all the tags I need to sort the collection. I meta tagged all my MP4 video with Mp3Tag v3.01, which is excellent util for the meta tagging via many different ways and easily expandable due to a simple text based plugin type feature.

I leave it here so maybe it’ll help someone else. config.xml, notably.

The import script. Function addVideo(obj) is when the only modified function and does all the heavy lifting for rhe menu.
