Connect to capture driver without creating window

How can I connect to video capture driver without creating a capture window. Is this possible ? In the other word, I want to capture video from user webcam without showing preview window.

Using VfW, you need to (at least) create the video/capture window, but you can give it a null window handle as the parent and make it not visible. All communication from the VfW library is done via StdCall callbacks. I'm not 100% but I don't think you need to run a message pump either.

As Roman says you should look at DirectShow as it obsoleted VfW about 15 years ago now.

You need to have a window only with legacy Video for Windows API. With DirectShow or Media Foundation, window is not necessary for video capture. In C# you can interface to those APIs using open source DirectShow.NET and Media Foundation.NET libraries.

FYI: DirectShow.NET includes CapWMV sample in C# that captures video into file.
