>&#13;        <SPAN
CLASS="application"
>GStreamer</SPAN
> is an exremely powerful and versatile framework for creating
        streaming media applications. Many of the virtues of the <SPAN
CLASS="application"
>GStreamer</SPAN
>
        framework come from its modularity: <SPAN
CLASS="application"
>GStreamer</SPAN
> can seamlessly
        incorporate new plugin modules. But because modularity and power often
        come at a cost of greater complexity (consider, for example, <A
HREF="http://www.omg.org/"
TARGET="_top"
>CORBA</A
>), writing new
        plugins is not always easy.
      </P
><P
>&#13;        This guide is intended to help you understand the <SPAN
CLASS="application"
>GStreamer</SPAN
> framework
        (version 0.7.4) so you can develop new plugins to extend the
        existing functionality. The guide addresses most issues by following the
        development of an example plugin - an audio filter plugin -
        written in C. However, the later parts of the guide also present some
        issues involved in writing other types of plugins, and the end of the
        guide describes some of the Python bindings for <SPAN
CLASS="application"
>GStreamer</SPAN
>.
