I have my own VR app where I display VR videos. Currently I use a Unity plugin to display the videos.
Is it possible to use DeoVR video player from my app?
I don't want to open up DeoVR app while the user is on my app.
You can setup your videos to be played in Deo https://deovr.com/doc
There's also a feature of remote playback, but deo needs to be launched. It's not a Unity asset.
