+// Joey suggested looking into libuvc which offers a more direct route to webcams over USB and this is very promissing but it wouldn't compile on windows for me...
+// I've gutted the classes I implemented DirectShow in just to have a skeleton for someone to work on, mail me for more details or if you want a copy....
