Today I just make it possible. Not using DLNA, but the best free video organizer in GitHub: Stash.
Because it's only possible with my modification, so for now you have to go to my cloned repo for the modified release:
https://github.com/philpw99/stash/releases
With Stash, you got a personal website that can organize all your performers, studios and scenes. Their community is at:
https://github.com/stashapp/stash
. Feel free to ask them quests in discord server. They are nice guys.
Now with my special modified Stash, you can browse and preview all your VR scenes, then click on a link to launch the file in VR, just like Skybox does. Quest 2 should be working.
