Class not registered

[oshuqair]

I am trying to run the VirtualCameraSample on windows 11 I have the windows SDK 10.0.22000.0 installed but yet am getting Class not registered on virtual camera start call RETURN_IF_FAILED(spVirtualCamera->Start(nullptr));

any hints?

Hi, yes probably because the vcam is not registered on the system. The sample requires 2 steps:

• first register the virtual camera on the target system (registering the COM component in the virtual camera dll). This is done by compiling and installing the .msi
• instantiate the virtual camera using an application: the app calls MFCreateVirtualCamera() using the CLSID of the COM component registered in step 1 followed by IMFVirtualCamera::Start())

my hunch is that step 1 is missing in your case resulting in that error
