Or C. OpenCV has nice examples.

For Video Capture, the external library needs to do most of the work
obviously, since this is the corner case for a scripting language.
(Even Delphi can be suboptimal depending on what you want to do
once you captured a frame)

I can say opencv worked great for me both on linux and windows
and didn't crash. Maybe you have just an unlucky combination
of drivers.
