Previously I shared how to use Touchless, which wraps the win32 APIs of DirectShow, to control webcam in C#. In this article, let’s take a further step to see how to use the more complicated DirectShow.NET APIs to capture the video stream and read barcode from preview frames on Windows. Resources for Learning DirectShow.NET DirectShow.NET...
