Is accessing the USB Video Class Extension Units supported in Metro Style App? RRS feed

  • Question

  • Hi,

    Is accessing USB Video Class Extension Units of a camera device allowed for a Metro style app? If yes, how to go about it.

    Current desktop way of accessing it is through the DirectShow capture filter(through IBaseFilter interface) which is no longer supported in Metro style app as Media Foundation is being used instead.

  • Kok Ann,

    Accessing the USB Video Class Extension Units is not supported in a Metro style app.  IKsControlInterface is not available to Metro style apps.  Therefore it is not allowed to circumvent this requirement by using the MFT0.

    Best Wishes - Eric
