You can do it easily (and multiplatform) with OpenCV - http://opencv.willowgarage.com/documentation/index.html . If you really need to use DShow ( or you just want to ) try windows SDK, should be full of code samples: http://msdn.microsoft.com/en-us/windows/aa904949.aspx . Here is a list of DShow examples in SDK: http://msdn.microsoft.com/en-us/library/dd375468(VS.85).aspx

I am doing just that at the moment! I have taken over Windows-based project that uses a combination of Qt, DirectShow/DirectX and OpenCV. It records from webcams.

However, there seems to be a little too much DirectShow/DirectX code in there if you ask me. So please post your findings to make it as Qt + OpenCV (and therefore portable) as possible. I will do the same.
