    <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.
