Thanks, @ShinyQuagsire (the author of the original visionOS Simulator -> Quest streaming tool over wired Meta Quest Link) for helping me with my wireless version.
Also thanks to @jjtech and @keithahern for figuring out simulator input, and to ALVR devs for an amazing streaming tool.

@zhuowei @jjtech @ShinyQuagsire @keithahern [↑] The ALXR client works with the SteamVR OpenXR runtime, and is compatible (to my knowledge) with bog standard ALVR servers, so it /should/ work in theory…

@akemin_dayo Thanks! I have not tried it.

I'm using the latest ALVR nightly since it has a few fixes to run the dashboard + server on macOS, which came in handy for this, but I think it's quite a bit ahead of the current ALXR version.

Also, the nightly ALXR is no longer compatible with vanilla ALVR, it seems; I guess only the stable version from last year is?

If ALXR still uses the same Rust->C++ interface as upstream ALVR, then you might be able to just swap in the ALXR server code? I only replace the C++ side and the Rust side is mostly untouched.

I'll take a look at how ALXR's client does passthrough. I think it just takes a mask color, right? I can render a greenscreen (https://notnow.dev/notice/AXTQmrNkveomxqdIrw)

I was planning to stream the actual alpha channel as black-white at the bottom of the video, but visionOS doesn't use alpha blending much (only on the window handles).

Most of it is frosted glass, which I can't do anything about, since only Meta Quest Link gets access to the real camera images.

I also recently picked up a PSVR1 with the intention of adding support, so I can also test on PSVR if you want.
