I had an old Elgato HD60 lying around. It can capture HDMI at 1080p60, which is plenty if you just want to use an external camera as a webcam with your Mac.
The problem is Elgato never properly supported it on macOS, especially not on Apple Silicon. So I made it work.
I ended up writing a userspace macOS driver for the original HD60. It gets the card up and running and streams 1080p60 H.264 video and audio into OBS. No kernel extension, no Rosetta, and no Elgato software needed at runtime.

This felt like a better example of what it’s actually useful for: I used it to help reverse-engineer and get a stubborn hardware problems working. It didn’t do the job for me, it just made a weekend project much more achievable.
