    <para>The <application>GStreamer</application> package contains a streaming
    media framework that enables applications to share a common set of plugins for
    things like video decoding and encoding, audio encoding and decoding, audio
    and video filters, audio visualisation, Web streaming and anything else that
    streams in real-time or otherwise. It is modelled after research software
    worked on at the Oregon Graduate Institute.</para>
