    Description

      QCamera objects for any USB Webcam on Windows 7 Ultimate system that has many codecs installed reports false from QCamera::isCaptureModeSupported(QCamera::CaptureVideo);
      On a related note, no-codecs are reported to exist.
      The camera is capable of capture as demonstrated by other software.
      This was tested with Camera example application and fails.
      Perhaps this is just a documentation problem, as it is not clear what, if any, other plug-ins are needed to access the codecs on windows (or any other platform). Only DSEngine.dll has been built as a plug-in and it is working. Still Capture works as does the ViewFinder. Only Video Capture fails to work.
