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.

TL;DR
Zsh initializations
- Zsh way of $PATH
- the special macOS
/usr/libexec/path_helper

Do not use forEach with async-await

TLDR: Use for...of instead of forEach() in asynchronous code.

For legacy browsers, use for(...;...;...) or [].reduce()

To execute the promises in parallel, use Promise.all([].map(...))

The problem

Encoding to Hap from the command line using FFmpeg

For users who prefer working with a command line or need to access advanced encoding settings for Hap the popular FFmpeg library can be used to work with Hap movies.

If this is your first time using FFmpeg you may need to install it on your system, or compile it from source. In either case be sure that Snappy is enabled as part of the binary. If you already have FFmpeg on your system with Snappy enabled, you can skip this step.

You can check that your version of FFmpeg can encode Hap using
```
ffmpeg -encoders | grep hap
```

Hybrid files

A short compilations of hybrid files I've used/modifies whats out there for my use.

What do I mean by hybrid files? A file that can be parsed by two or more scripting lanauges and run (without or minimal error messages)
