About intel/libva
Libva is an implementation of the Video Acceleration API (VA-API), an open-source library and API specification that 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. The project is maintained by Intel and is designed for backward compatibility, ensuring no regressions in existing API support.
Key Features
Hardware-accelerated video encoding and decoding via VA-API
Open-source library with driver-specific backends for multiple vendors
Backward compatible API with stable interface guarantees
Supports building with autogen and Meson build systems
Actively maintained by Intel with community contributions
Pros & Cons
Pros
- Free and open-source under an open license
- Provided by Intel, ensuring long-term support and industry adoption

FAQ
What is libva?
Libva is an implementation of the Video Acceleration API (VA-API), an open-source library and API specification for accessing graphics hardware acceleration capabilities for video processing.
What hardware does libva support?
Libva supports multiple hardware vendors through driver-specific acceleration backends. The project is developed by Intel and commonly used with Intel integrated graphics, but backends for other vendors are available.
How can I build libva from source?
You can build libva using autogen or Meson. Required packages include git, cmake, pkg-config, meson, libdrm-dev, automake, and libtool. Clone the repository, then run either ./autogen.sh or mkdir build && meson build.
Is libva backward compatible?
Yes, no code changes may be introduced that would regress support for existing API. All contributions must maintain API compatibility. Changes to stable API are communicated in release notes.
