Integrates the NDI® SDK with Godot

[ NDI® is a registered trademark of Vizrt NDI AB ]

Extends the VideoStream and VideoStreamPlayback classes to implement NDI playback. For outputting the Viewport as an NDI source, add the NDIOutput Node to the scene. Check out the demo scenes included with the releases.

I'm happy to hear suggestions and incorperate improvements. You can find my contact info on my Github profile.

Install

[!IMPORTANT]

• Only compatible with Godot 4.4-beta1 and later

Download the latest version under Releases. Install by extracting the ZIP file in your Godot project.

The NDI Runtime is also required.

• NDI Runtime for Windows
• NDI Runtime for MacOS
• NDI Runtime for Linux (Doesn't work with flatpak editor since that's sandboxed)

Your application needs to comply with the NDI SDK license.

Building from source

This project is based on the typical Godot build system.

There is a Dev Container configured that will allow you to target Linux. If you want to target Windows you could install MSYS2 and run scons use_mingw=yes for example.

Generally, improvements to the source code must be made available under the same license. See license text.
