Does anyone have any knowledge or experience with Apple's fisheye projection type? I'm guessing that it's as the name implies: a circular capture in a square frame (encoded in MV-HEVC) that is de-warped during playback.
It'd be nice to be able to experiment with this format without guessing/speculating on what to produce.
Just adding a comment that fisheye projection could be along the lines of what Google has described in their spatial media specs: https://github.com/google/spatial-media/blob/master/docs/vr180.md
Commenting here to see if Apple comments on this. It would be a great help for other users trying to create content similar to the one presented in the Apple TV app for Vision Pro.
