This is a step by step tutorial for writing a simple DirectShow video capture application in .NET by using VideoLab or VisionLab. The steps are exactly identical in C#, Visual Basic .NET, C++/CLI and J#.
Using the application created by following the tutorial, you will be able to capture from Webcam, Camcorder, Camera, TV Tuner, DVR, VCR, DVD Player, or any other video source.
WARNING: In order to run the application in this example you must have DirectX 9.0 or higher installed on your system!
There is no code writing necessary to complete this application.
There is no need to know C#, Visual Basic, J# or C++ in order to create this application.
The tutorial covers the following steps, which should take less than two minutes:
1. Add a DSCapture Component to Your Application's Form:
2. Add a DSImageDisplay Control to Your Application's Form:
3. Add a DSVideoLogger Component to Your Application's Form:
