How can i make custom video feed instead of using camerafeed like in the 8thWall cloud editor?

I am doing local develop project with Three.js and i want to display video instead of real-time camera feed on the desktop. The thing i want to do is exactly same as 8thWall cloud editor’s video background changing for the AR test.

Is it related with XR8.GLTextureRenderer?
If so, what should i do?

Still have no clue, Is it possible to make video background(like mp4 video) to use fake camera stream for AR instead of the real camera stream?

This is not supported at the moment, but it is a great feature request.
Can you share some more details on your use-case?

Any update??
It would be very useful, especially for demo and debug purpose!
