    <para>
      <application>gstreamer</application> is a streaming media framework that
      enables applications to share a common set of plugins for tasks such as
      video encoding and decoding, audio encoding and decoding, audio and video
      filters, audio visualisation, web streaming and anything else that
      streams in real-time or otherwise. This package only provides base
      functionality and libraries. You may need at least <xref
      linkend="gst10-plugins-base"/> and one of Good, Bad, Ugly or Libav
      plugins.
