A camera or microphone isn't listed

Press Rescan under Sources — USB cameras connected after launch aren't picked up automatically.

If it's still missing, confirm another app can see it, and check that OdinCam has camera and microphone permission in System Settings under Privacy & Security. These are two separate permissions, and OdinCam works with only the camera — you simply lose sound detection.

If a camera is unplugged while selected, OdinCam falls back to another one rather than stopping.
