      <para>
        The <application>libvdpau-va-gl</application> package contains a library
        which implements the VDPAU library.  Libvdpau_va_gl uses OpenGL under the
        hood to accelerate drawing and scaling and the VA-API (if available) to
        accelerate video decoding. For now VA-API is available on some Intel
        chips, and on some AMD video adapters with the help of the libvdpau
        driver.
