    <para>The <application>GStreamer Base Plug-ins</application> is a
    well-groomed and well-maintained collection of
    <application>GStreamer</application> plug-ins and elements, spanning the
    range of possible types of elements one would want to write for
    <application>GStreamer</application>. It also contains helper libraries
    and base classes useful for writing elements. A wide range of video and
    audio decoders, encoders, and filters are included. Also see the
