Code to test other code.

If you need a test, look here.

If you create a new test, add it here.

If you know of some tests that are not listed, please add it.

Test Driver(s)

VIVI - Virtual Video Driver http://v4l.videotechnology.com/vivi.html

A real v4l2 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 not

  • perfect. Not surprising given it doesn't get the amount of real world use that real drivers do.
  • feature complete. It does not implement every interface of the v4l2 spec (yet.)

But it is something anyone can run, so it makes reproducing some problems possible that would otherwise be impossible without the specific hardware.

Test applications

Simple programs that test various functionality of a driver.
