Hello Everybody!I'm now using the KSStudio to test the API of my USB Camera's driver. The step is as following:1. Open KSStudio and double-click the device name under "KSCATEGORY_CAPTURE Filter Factories" in Filter Factory view.2. Click "Misc. Supported PropertySets" in Object Details view. Right-click on a property, like KSPROPERTY_VIDEOCONTROL_ACTUAL_FRAME_RATE, and click Refresh. Then the Logging Window output:Getting property KSPROPERTY_VIDEOCONTROL_ACTUAL_FRAME_RATE KSPROPERTY_VIDEOCONTROL_ACTUAL_FRAME_RATE get failedI'm not sure if this means my driver is incorrect or my operation is incorrect. Any one who can help me will be greate appreciated!
