      Inconsistent camera/video inputs between Qt 5.15 and 6.5 on Windows.

      When run under Qt 5.15 my app sees (QtMultimedia.availableCameras):

      • Integrated camera
      • OBS Virtual camera

      When run with Qt 6.5.1 I get from (ffmpeg or windows backend, no difference) MediaDevices videInputs:

      • Integrated camera
      • Integrated IR camera

      OBS Virtual camera is missing. Both of the above do produce video.
      Debug output (id, description)
