I want to implement an immersive environment similar to AppleTV's Cinema environment for the video that plays in my app - currently, I want to use an AVPlayerViewController so that I don't have to build a control view or deal with aspect ratios (which I would have to do if I used VideoMaterial). To do this, it looks like I'll need to use the imagery from the video stream itself as an image for an ImageBasedLightComponent, but the API for that class seems restrict its input to an EnvironmentResource, which looks like it's meant to use an equirectangular still image that has to be part of the app bundle.
Does anyone know how to achieve this effect? Where the "light" from the video being played in an AVPlayerViewController's player can be cast on 3D objects in the RealityKit scene?
Is AppleTV doing something wild like combining an AVPlayerViewController and VideoMaterial? Where the VideoMaterial is layered onto the objects in the scene to simulate a light source?
Thanks in advance!
