Delphi FireMonkey TCaptureDeviceManager.Current.GetDevicesByMediaType(TMediaType.Video) always returns empty list

  

I’m using code from this wiki
http://docwiki.embarcadero.com/RADStudio/XE8/en/Video_Capturing

but

TCaptureDeviceManager.Current.GetDevicesByMediaType(TMediaType.Video);

Always returns empty list (i have webcam attached and other apps see it).
Googling didn’t give me any responses.

Could you please tell me what could cause this problem, as this component is critical for my project.
