Parameters
- sampleTimeInHundredNanoseconds

The time, in 100-nanosecond units, when the sample was captured.
- frameDurationInHundredNanoseconds
Type: System.Int64
The duration of the sample, in 100-nanosecond units.
- sampleData
Type: array<System.Byte[]
A byte stream that contains video data. The byte stream should be processed into samples according to the relevant video format information.
Remarks
A complete sample is one video frame, with the frame rate reported in VideoFormat.FramesPerSecond for the associated VideoCaptureDevice. To work with the sampleData, you may also need to know other properties as reported in VideoFormat.
Each time a frame is ready from a video capture device, this method is called.
