Question about MediaCapture::AddEffectAsync.

    Question

  • We can insert a video effect to webcam video stream by call AddEffectAsync:

    1. From MSDN, the parameter 'mediaStreamType ' specifies the streams to which the effect will be applied.

    When I set the 'mediaStreamType ' to MediaStreamType::VideoRecord, I found that the effect also be applied to the preview.

    Is this a BUG or original design?

    2. 'effectActivationID ', The class identifier of the activatable runtime class that implements the effect. The runtime class must implement the IMediaPlugin interface.

    But I didn't see the sample MFT_GrayScale implement 'IMediaPlugin ', but it still can work.

    Any one can help to answer these 2 questions?

    Thanks in advance.
