Remarks

Obtain instances from VideoCaptureCore.Video_MediaFoundationCaptureDevices. This is not a VisioForge.Core.Types.VideoCapture.VideoCaptureDeviceInfo: there is no crossbar, audio pin, tuner, or DirectShow format list. Pass the instance to VisioForge.Core.Types.VideoCapture.VideoCaptureSource.#ctor(VisioForge.Core.Types.VideoCapture.MediaFoundationCaptureDevice).

Each format is a size the camera's own Media Foundation source reports, with the frame rates reported for that size. The capture graph receives RGB24 at the chosen size. A size that appears only in the DirectShow device list is not included.

Constructors

MediaFoundationCaptureDevice(string, string, IList<MediaFoundationCaptureFormat>)
