      This book is about &GStreamer; from an application developer's point of view; it
      describes how to write a &GStreamer; application using the &GStreamer;
      libraries and tools. For an explanation about writing plugins, we
      suggest the <ulink type="http"
      url="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/pwg/html/index.html">Plugin
      Writers Guide</ulink>.

      Since &GStreamer; adheres to the GObject programming model, this guide
      also assumes that you understand the basics of <ulink type="http"
      url="http://library.gnome.org/devel/gobject/stable/">GObject</ulink> and <ulink type="http"
      url="http://library.gnome.org/devel/glib/stable/">glib</ulink> programming.

    <title>Structure of this manual</title>
    <para>
      To help you navigate through this guide, it is divided into several large
      parts. Each part addresses a particular broad topic concerning &GStreamer;
      appliction development. The parts of this guide are laid out in the following
      order:
    </para>

    <para>
      <xref linkend="part-introduction"/> gives you an overview of &GStreamer;,
      it's design principles and foundations.
    </para>

    <para>
      <xref linkend="part-building"/> covers the basics of &GStreamer;
      application programming. At the end of this part, you should be
      able to build your own audio player using &GStreamer;
    </para>

    <para>
      In <xref linkend="part-advanced"/>, we will move on to advanced
      subjects which make &GStreamer; stand out of its competitors. We
      will discuss application-pipeline interaction using dynamic parameters
      and interfaces, we will discuss threading and threaded pipelines,
      scheduling and clocks (and synchronization). Most of those topics are
      not just there to introduce you to their API, but primarily to give
      a deeper insight in solving application programming problems with
      &GStreamer; and understanding their concepts.
    </para>

    <para>
      Next, in <xref linkend="part-highlevel"/>, we will go into higher-level
      programming APIs for &GStreamer;. You don't exactly need to know all
      the details from the previous parts to understand this, but you will
      need to understand basic &GStreamer; concepts nevertheless. We will,
      amongst others, discuss XML, playbin and autopluggers.
    </para>

    <para>
      Finally in <xref linkend="part-appendices"/>, you will find some random
      information on integrating with GNOME, KDE, OS X or Windows, some
      debugging help and general tips to improve and simplify &GStreamer;
      programming.
    </para>
