Multi-channel video NDI livestream


I’m trying to make a multi-channel video installation with 4x Raspberry pi 4 models.
For the final exhibition, I’ve been able to setup the loop and sync video system by connecting the raspberries with a switch and using MP4Musuem (which is a great tool for video artists).

At the moment, I would like to make changes live during installation tests. In my video editor, I have put the 4 videos into 1 (imagine 4 tiles on 1 screen) for ease of editing. So I would like to stream from my video editor and split the image 4 times so the raspberries will play different parts of the same video. I have setup up a program called Dicaffeine which allows NDI from my computer to the raspberries. I just don’t know how to split/crop the video when the raspberries recieve it. about [Dicaffeine]

Is there something like the Pi wall effect but with NDI live video?

(I have very limited experience, but have an IT friend who can help out).

Thanks so much,


Hi Allison,

Welcome to the forum!!

Very interesting project! I noticed that UVC is an option as an output, I’d take a look at using OBS’s(Open Broadcasting Software) UVC output (I’ve fiddled around with it a little but only within my PC).

Depending on your graphics card you might be able to emulate a virtual monitor using a HDMI dummy plug.

I’m not 100% sure what the best route might be here!

Thanks for the suggestion Liam.

I’ll look into OBS and will continue searching for other programs that can facilitate this setup.
