Capturing Video in Managed Code
Dan Fernandez, Senior Product Manager in the Devloper Group answered a question on our internal list servers this week that I wanted to share because it answers a quesion that I myself have asked recently.
Are there rtesources for capturing video in Managed Code.
The answer is YES !
If you’re running Windows XP, you can use a little-known XP feature called Windows Image Acquisition (WIA) that has a COM library you can program against. This makes capturing either a single frame of a picture or video stream from a USB web cam as easy as 1-2 lines of code.
MSDN Windows Image Acquisition docs –

There is also an open source project to program a webcam across any operating system that may interest you - http://libusb.sourceforge.net/
