Displaying HDMI sources on Apple Vision Pro

While it's possible to stream most content to Apple Vision Pro directly over the internet, having the ability to use Apple Vision Pro as an HDMI display can still be useful.

Since Apple Vision Pro does not support connecting to an HDMI input directly or using an HDMI capture card, we have to be a little creative to make this work. NDI provides the ability to stream HDMI content over a local network with really low latency, and it works great with Apple Vision Pro.

This page shows the setup I’m using.

If you have a Linux machine with KVM on it, you can manage those VMs remotely from a Mac using virt-manager.

Step 1: Allow your user non-root access to KVM

SSH to the Linux machine and add your SSH user to the libvirt group

sudo usermod -a -G libvirt $(whoami)

Note This is a little out of date. Rust has made some progress on some points, however many points still apply.

Philosophy

Progressive disclosure

Swift shares Rust's enthusiasm for zero-cost abstractions, but also emphasizes progressive disclosure. Progressive disclosure requires that language features should be added in a way that doesn't complicate the rest of the language. This means that Swift aims to be simple for simple tasks, and only as complex as needed for complex tasks.

Example

To remove a submodule you need to:

Delete the relevant section from the .gitmodules file.
Stage the .gitmodules changes git add .gitmodules
Delete the relevant section from .git/config.
Run git rm --cached path_to_submodule (no trailing slash).
Run rm -rf .git/modules/path_to_submodule (no trailing slash).
Commit git commit -m "Removed submodule "
Delete the now untracked submodule files rm -rf path_to_submodule
