Webcam Controls Tests (System)

These set of tests validate cameras functionality if the driver supports KSPROPERTY_CAMERACONTROL_EXTENDED_*. If the driver does not support KSPROPERTY_CAMERACONTROL_EXTENDED_*, skip this test. This is an optional control.

If a driver does not support a control, do not implement a control handler. If a control handler is implemented, the registered test will expect the control to be fully functional.

If a driver implements a control handler, the following checks run (based on the definition of the controls):

  • The test verifies default values and validates that the appropriate property is advertised on the correct pin or filter level.

  • The test enumerates possible control values during the times that pins are streaming and not streaming.

  • Scenario tests are run on the control to determine the end-to-end functionality.


Implementation of extended controls, such as photo mode, require that you implement additional extended controls.
