Libva-utils Project

libva-utils is a collection of utilities and examples to exercise VA-API in accordance with the libva project. --enable-tests (default = no) provides a suite of unit-tests based on Google Test Framework. A driver implementation is necessary to properly operate.

VA-API is an open-source library and API specification, which provides access to graphics hardware acceleration capabilities for video processing. It consists of a main library and driver-specific acceleration backends for each supported hardware vendor.

If you would like to contribute to libva, check our Contributing guide.

We also recommend taking a look at the 'janitorial' bugs in our list of open issues as these bugs can be solved without an extensive knowledge of libva-utils.

We would love to help you start contributing!

The libva-utils development team can be reached via github issues.
