CHROMIUM: Reset tree to upstream/2.20.0 BUG=b:308373300 TEST=emerge-rex libva-utils Change-Id: Iea45d55b37e83b1ce7fe1be3fae4225d7707fd17
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!
