xbapps/xbvr: Tool to organize and stream your VR adult library (github.com)
XBVR is a tool that stores adult-focused VR videos. It organizes them, scrapes metadata for them from the most popular websites, and has a proper setup to allow playback from the most popular VR players. It has a DLNA server as well as an interface/API that can be leveraged from DeoVR.
The current dev container is a bit rough - Docker Hub
It has no latest tag or beta tag, so you need to specify the version and modify that for any upgrades. Also, it does not have any way to configure file permissions or ownership, so generated previews and metadata are all stored with root:root ownership.
