If you have an iPhone+mac you can use continuity camera which is pretty seamless in comparison: https://support.apple.com/en-us/HT213244

I've created PTP Webcam [1] during COVID to get DSLRs working for video conferencing on the Mac.

Earlier quoted context omitted.

Normally you can leave live view (768x512 resolution, 0.4 MP in this case, usually not much higher for modern cameras) running indefinitely. Besides the low resolution especially on older cameras the readout for live view will use pixel skipping to conserve power at the expense of quality. This is why "the pro streamers" don't use the live view image, but instead go the HDMI-to-UVC route using the camera's video mode…

Unfortunately most cameras do not provide "clean" HDMI output. That is, the HDMI output contains camera UI symbols like focus points, battery state, lighting, etc. Configuration options to disable those UI symbols are generally not available, at best one can disable some of them. A model with "clean" HDMI is usually more expensive and you have to explicitly look for it as a feature. Live view readout via USB is somet…

I’d expect pretty much any system camera from the last decade should include it

You are definitely expecting something that the camera makers' market segmentation does not provide. If you need clean HDMI, you can buy a camera that has it, but I estimate only a quarter of currently available DSLRs do.

whole guide about using some gphoto software, yet not a single link in article

btw it's only for Linux, so don't even bother reading the linked web, if you are in windows

Correct title:

How to use your DSLR from 2008 as a webcam IN LINUX in 2022 (NixOS)

I wished people would not omiss such important information in title when writing articles or linking them wasting everyone's time including server traffic

Any restrictions about how long you can keep it turned on? I tried to do this but found I'd need to flash the cam's firmware to override the 10min recording limit. (I read that cameras which can record longer are taxed as video cameras, so they're deliberately crippled)

Magic Lantern will take care of that.

To accomplish what the OP does, I use a USB HDMI in, a mini HDMI to HDMI cable, and Magic Lantern on my Rebel. It works well.

Magic Lantern allows me to leave the camera in preview without overlays for indefinite time periods. It can also provide video this way, but heat can be an issue there…

There are lots of solutions that are more seamless than the DSLR, but which are vastly more expensive, including just buying a webcam proper. But the fact that you _can_ use the DSLR as your webcam is cool, and may save some folks money if they happen to have a DSLR laying around.
