VidCapture 0.30 has been released!
Now with improved multiple camera and input format support.
VidCapture is a library (in both static .lib and DLL format) that provides simplified access to video capture devices through DirectX for computer vision and image processing.

The VidCapture library has now been moved to SourceForge!
Currently, it works on Win32 only and is geared towards web cameras. If you'd like to help enhance it, port it, or create wrappers for it for various languages/environments - let me know.
