Really appreciate the time and effort you're putting in to this project. I'm a hobbyist back yard blacksmith with some pretty basic tech background. I've been using an old MacBook to do some YouTube live streams for friends and family during this covid crap, and the GPU on the MacBook finally took a complete dump. I've got about 10 Pi3's laying around so thought I'd dig in to this option a bit. Loaded on a Pi3 for proof of concept and was super impressed with the ease of installation. Ordered a Pi4 and seems I'm still not going to be using any USB webcams... so with the biography out of the way, now a question... How is the performance with a PiCam? How bout multiple PiCams?
