I've found OBS Studio to be brilliant. I needed to capture and livestream the screen of a small embedded Windows box. I purchased an HDMI-in/USB-out HD capture device. Plugged the HDMI side into the little Windows box, and the USB side into my linux box. OBS Studio recognized the new "HD Capture" virtual device, and captured the live video off the other system. I could save to a file, livestream, etc. No driver issues or problems. Just amazing.
