take picture from webcam c#

Question

I'm streaming video to my Window Form with DirectShowLib. I also want to save image when i press button "Save" for example. How to get picture from webcam with DirectShowLib methods or with WIN32 API methods?

Answer 1

DirectShow.NET Samples are there: http://sourceforge.net/projects/directshownet/files/DirectShowSamples/2010-February/ The following sample demoes the requested function:

Samples\\VMR9\\vMR9Snapper ------------------------ This sample shows how to capture bitmaps from VMR9.

Having it working with other renderer might require small code modifications.

The question also discussed a multitude of times at MSDN Forums, and on CodeProject, eg how to save bmp file from IVMRWindowlessControl9->GetCurrentImage() .
