cannot get life feed from webcam under Windows (Bug #580)
Description
I checked out opencv 2.1.1 from trunk (Revision: 3648) and I successfully compiled it under windows 7 (64-bit) using Visual Studio 2005 (32-bit - hence all the binaries are 32 bits).
All the examples seem to be working just fine, except for the fact that I cannot capture from the built-in webcam (it works just fine under 2.1). The program (for example camshiftdemo.exe) does not crashes. It simply displays a black image.
If I pass a video file, everything is fine.
I did not enable the Qt interface when compiling.
I have also compiled 2.1 on the same system and everything works just fine.

I think it may be related to #491
I think HAVE_VIDEOINPUT is not working as expected...
Try doing what I did in the 3rd reply in that ticket and see if that fixes it.
