    <title>Introduction to libva</title>

    <para>
       The <application>libva</application> package contains a library which
       provides access to hardware accelerated video processing, using hardware
       to accelerate video processing in order to offload the central
       processing unit (CPU) to decode and encode compressed digital video. The VA
       API video decode/encode interface is platform and window system
       independent targeted at Direct Rendering Infrastructure (DRI) in the X
       Window System however it can potentially also be used with direct
       framebuffer and graphics sub-systems for video output. Accelerated
       processing includes support for video decoding, video encoding,
       subpicture blending, and rendering.

        form of libva*.so.1 and any symbolic links pointing to them.  In
        addition, any packages that use these files need to be rebuilt.
