Yes, you can do this with OBS. The virtual webcam feature can be added as a plugin. And chroma-keying is a built-in feature. I use a Mac, and I've been toying with this a bit over the last weeks (e.g. https://davidbieber.com/snippets/2020-04-09-exploring-obs/ https://davidbieber.com/snippets/2020-04-09-exploring-obs/)

It's super easy...if you have a suitable chromakey backdrop and decent lighting on it. What I'd love is a plugin that replicates (or at least approximates) some of the "virtual chromakey" features of Zoom et al. I don't currently have access to a good chromakey backdrop and it really is much easier to do it well with a bright green matte screen behind you. It ain't important, but it would sure be nice!

  For Windows, Snapchat have a standalone virtual cam called Snapcamera https://snapcamera.snapchat.com/ https://snapcamera.snapchat.com/ There are green screen plugins for that. You could chain Snapcamera's virtual cam output into OBS and use OBS 's chromakey filter to underlay whatever other content you like. Y I u can then output OBS to another virtual cam output for use in Zoom or wherever else via the Virtualcam plugin for OBS. It'd be really nice if someone would make a nice OpenCV virtualcam output so one could drive all this from a (relatively) simple Python script.

    Oh hey, this worked fairly well. I used one of the Snap fake-greenscreen filters and fed it to OBS as you suggested. It really does highlight the limitations of fake-chromakey (edges are fuzzy/flickery) but that's to be expected without a real, properly lit backdrop. I won't be using this in any work meetings but it could be fun for calls with friends.
