DEPRECATED, use OnFrameBitmap instead. Put your code in this event to apply any processing to each video frame, through its DIB bitmap. This event occurs for each video frame that goes through the video stream, during preview, recording or playback. The frame grabber must be enabled for this event to occur. This event offers a full access to the DIB bitmap of each video frame. This event is TIME CRITICAL: the code used in this event must be as short and fast as possible. Sample code is included in the MainDemo project. To get information about the current video frame, invoke GetFrameInfo (FrameId, ...). E.g. SampleTimeHour = VideoGrabber.GetFrameInfo (FrameId, fi_SampleTime_Hour).
