Virtual Camera enabled but not showing up in Windows 10

[riparianyellow]

Virtual camera is started, I'm running a looped video, and even disconnected my usual webcam, but no camera is detected when testing with various software, including the built-in Windows camera app. I tried rebooting to no avail. Any ideas?
