Testing Video4Linux Applications and Drivers - Hans Verkuil

Sign up or log in to save this to your schedule and see who's attending!

The video4linux subsystem of the kernel is a very large API with many ioctls, settings, options and capabilities. This poses a problem both for the kernel developer and for the application developer. Since early 2014 major improvements have been made to both the v4l2-compliance utility for verifying drivers, and to the virtual video driver that applications can use as a reference input. This presentation will explain and demonstrate this utility and driver and show how to use them to ensure your driver or application works correctly.
