VIVI - Virtual Video Driver http://v4l.videotechnology.com/vivi.html
A real device driver with no physical hardware. This means anyone can use it. If your application has problems with a specific device driver, try using vivi instead. If you still have a problem, it is much more likely to be a problem with the application than with the driver. Knowing where to look is a big help in fixing problems.
However, vivi is a) not perfect and b) not feature complete. but it is something anyone can run, so it makes reproducing some problems possible that would otherwise be impossible without the specific hardware.
Simple programs that test various functionality of a driver.
