I got Apple's visionOS Simulator streaming wirelessly to a Meta Quest using ALVR.

@zhuowei that’s fantastic, did it also free up some CPU/GPU time?

currently the left eye is much laggier than the right eye, but it works and it's stereo-correct and that's what matters

@ShinyQuagsire I'm successfully sending Magic Leap eye data (well a unified gaze direction vector) and pinch boolean to the XRGyroControls.

@zhuowei OBS made the chroma keyed stream available as a virtual camera device, I then streamed that over webRTC to the Magic Leap which was also sending gyro events. It was laggy and I haven't gone back to optimise.
@zhuowei I played around with this using OBS and chroma keying out colours while looking at blocks of colour in the sim. Due to the inherent alpha blending of the app icon grid and frosted glass panels it didn't look great. Are you able to isolate the layers pre-composition?
@zhuowei VP8/VP9 does it and some Quicktime codecs such as ProRes 4444
