DxDiag code for Camera Location

Question

Abraham Carrillo 36

DxDiag shows us for Video Capture Devices the location of the camera (Front or rear).

I need to know how to do it in a windows forms c# application.

I don't have the option to use UWP.

Thank you

Hi @Abraham Carrillo ，Welcome to Microsoft Q&A,

What do you mean Front or rear? What do you mean the option to use UWP? Do you want to create a UWP Application?

Hi @Anonymous

when you save the info of DxDiag, you can get the info of the Video Capture Device physical location, that´s means Fornto or Rear.

In UWP you can get that info, but I can´t use UWP

@Anonymous I understand that a UWP app has to be registered and distributed through the Microsoft store. The verification of the camera location, I need it for a Windows Forms application that uses DirectShow.

Hi @Abraham Carrillo ，Are you creating a UWP program or a winfrom program? This will have corresponding personnel to deal with your issue. And your answer keeps going off topic. What UWP API are you trying to use?

From docs (I have no real camera to test), it could be PKEY_Devices_PhysicalDeviceLocation (with SetupDi APIs)

6.1.8. _PLD (Physical Location of Device)

@Castorix31 Thanks.
I´m using DEVPKEY_Device_LocationInfo, this property return a string, in my case for the front camera returns "0000.0014.0000.008.000.000.000.000.000".

How do I interpret this string for the camera Front and Back?
Regards.

DEVPKEY_Device_LocationInfo is not the same Guid as PKEY_Devices_PhysicalDeviceLocation = DEVPKEY_Device_PhysicalDeviceLocation (returns _PLD from doc)
