    <para>
      <application>gstreamer</application> is a streaming media framework that
      enables applications to share a common set of plugins for things like
      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.
