No way to detect if a camera device is in use by another application. After calling StartCapture() the SDK just sits there, no errors are posted. Serious issue for professional use!

That's no standard ways in DirectShow to detect this. Usually SDK returns an error, but not for all devices.

I have used IMediaControl.Run() returning as 0x800705aa or 0x80070057 to interpret as device in use.
The SDK however does not forward these errors, even though I know the particular device does return 0x800705aa.

SDK returns IMediaControl.Run() HRESULT if not 0 using OnError event.
