Hi,

We have a requirement to get the camera devices and the status of them on a PC. The launguage uses C#.
We tried to use SetupDiEnumDeviceInterfaces to enum all the device interface on the PC, but there is not a flag to show which device is a camera.
We also tried to use WMI API to get camera device, but it seems no camera devices listed.

Could any one give me some suggestions?
And about the status (enabled/disabled) of the device, how to obtain it?

    With SetupDI APIs, you can get them with Class Guids like Camera Device, Imaging Device, USB
    (System-Defined Device Setup Classes Available to Vendors)
    I have only a Virtual Camera and I get it with Imaging Device {6bdd1fc6-810f-11d0-bec7-08002be2092f}

    You can also use DirectShow
    I had posted a sample adapted from MS SDK in this thread in VB (easy to convert into C#, function FindCaptureDevice)
