    <title>Introduction to libvdpau</title>

    <para>
      The <application>libvdpau</application> package contains a library which
      implements VDPAU.
    </para>

    <para>
      VDPAU (Video Decode and Presentation API for Unix) is an open source
      library (libvdpau) and API originally designed by Nvidia for its
      GeForce 8 series and later GPU hardware targeted at the X Window System.
      This VDPAU API allows video programs to offload portions of the video
      decoding process and video post-processing to the GPU video-hardware.
    </para>

    <para>
      Currently, the portions capable of being offloaded by VDPAU onto the GPU
      are motion compensation (mo comp), inverse discrete cosine transform
      (iDCT), VLD (variable-length decoding) and deblocking for MPEG-1, MPEG-2,
      MPEG-4 ASP (MPEG-4 Part 2), H.264/MPEG-4 AVC and VC-1, WMV3/WMV9 encoded
      videos.  Which specific codecs of these that can be offloaded to the
      GPU depends on the version of the GPU hardware; specifically,
      to also decode MPEG-4 ASP (MPEG-4 Part 2), Xvid/OpenDivX (DivX 4), and
      DivX 5 formats, a GeForce 200M (2xxM) Series (the eleventh generation of
      Nvidia's GeForce graphics processing units) or newer GPU hardware is
      required.
