What the independent test changes
If DeviceOK passes
A working physical camera narrows the failure toward OBS Virtual Camera or the receiving application's camera selection.
If DeviceOK fails
A physical camera failure should be resolved before diagnosing the virtual-camera layer.
Check these in order
- 1
Confirm the physical webcam/source works before involving Virtual Camera.
- 2
Start OBS Virtual Camera and check the target app's selected camera.
- 3
Follow OBS's official virtual-camera troubleshooting for platform-specific failures.
- 4
Retest the target app after restarting it if it enumerates cameras only at launch.
Retest instead of guessing
After changing one setting, run the independent DeviceOK test again before moving to a more invasive step. This preserves evidence and avoids changing multiple variables at once.
