DecklinkSDK.Net

Displaying a single image frame or multiple frames at a specific frame rate via a Blackmagic® card is extremely easy and effortless using our SP package.
It provides you with StillSource Filter and PushSource Filter capabilities at a single function call. It also extends the capabilities of the both filters to enable
Internal Keying or External Keying.

This way, you can overlay the 32-bit image frame over the incoming video feed. This feature can be extended to go beyond creating image frames, but
also overlaying 32-bit video files over the incoming feed.
DecklinkSDK.Net enables you to:

• Configure multi-cards on your machine
• Control keying settings and modes 
• Get card features and capabilities. 
• Push image frames to hardware. 
• Push image frames at a specific Frames Per Second.
• Control card input/output & much more... 

Applications

• Closed caption applications.
• Water marking demos or live feed. 
• Inserting live graphics over video feed.

Example Code

The below sample c# code demonstrates displaying a running clock over the main feed of a Decklink® card. //Get first available Blackmagic Card. DecklinkCard aCard = BMDevice.GetAvailableDevices()[0]; DecklinkStillSource  StillSource = newDecklinkStillSource(aCard); //Create a new empty bitmap and send it to decklink BitmapaFrame =newBitmap(PalWidth, PalHeight, PixelFormat.Format32bppArgb); StillSource.StartInternalKeying(); StillSource.Start(aFrame, PreviewLabel);   Graphicsg = Graphics.FromImage(aFrame);   while(isRunning) {     //generate image containing new time.     g.Clear(Color.Transparent);     g.DrawString(DateTime.Now.ToLongTimeString(), aFont,Brushes.Yellow, 50, 50);     //send it to decklink.     StillSource.UpdateDisplayImage(aFrame);       Thread.Sleep(1000);//wait one second }
