Declaration
property OnFrameOverlayUsingVIDEOHDR: TOnFrameOverlayUsingVIDEOHDR read FOnFrameOverlayUsingVIDEOHDR write FOnFrameOverlayUsingVIDEOHDR;

Description
DEPRECATED, use OnFrameBitmap instead
This TOnFrameOverlayUsingVIDEOHDR event is used to draw graphic objects over video frames, by using a VIDEOHDR video frame format.
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.
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)
