IOCTL_CAMERA_DEVICE_QUERYVIDEOFORMATS not working

Feb 5, 2009 at 4:32 PM
Hi,

did anyone ever try IOCTL_CAMERA_DEVICE_QUERYVIDEOFORMATS? It always reports an error -3 to me. IOCTL_CAMERA_DEVICE_QUERYSTILLFORMATS works fine. Even CamTest2 uses hard coded values instead of querying them. Makes a strange feeling if this functions has never been used anywhere ...

regards
Marco
