<!-- ############# Overview - part ############### -->
<part id="part-overview"><title>Overview</title>
<partintro>
<para>
<xref linkend="part-overview"/> gives you an overview of
<application>GStreamer</application> design goals.
<xref linkend="part-basic-concepts"/> rapidly covers the basics of
<application>GStreamer</application> programming.
In <xref linkend="part-build-app"/> we will move on to the
examples. Since <application>GStreamer</application> uses <ulink
url="http://developer.gnome.org/arch/gtk/glib.html" type="http">GLib
2.0</ulink>, the reader is assumed to understand the basics of the
<ulink url="http://developer.gnome.org/doc/API/2.0/gobject/index.html"
type="http">GObject object model</ulink>.
For a gentle introduction to this system, you may wish to read the
<emphasis><ulink url="http://www.gtk.org/tutorial/" type="http">GTK+
Tutorial</ulink></emphasis> or Eric Harlow's book <emphasis>Developing
Linux Applications with GTK+ and GDK</emphasis>.

<part id="part-basic-concepts"><title>Basic Concepts</title>
<partintro>
<para>
We will first describe the basics of
<application>GStreamer</application> programming by introducing the
different objects needed to create a media pipeline.
</para>
<para>
We will use a visual representation of these objects so that we can
visualize the more complex pipelines you will learn to build later on.

<para>
With the basic concepts out of the way, you're ready to start building a
full-scale <application>GStreamer</application> application.
</para>
<para>
We assume the reader is familiar with GTK+/GNOME programming.

<partintro>
<para>
In this part we will cover the more advanced features of <application>GStreamer</application>.
With the basics you learned in the prevous part you should be
able to create a 'simple' pipeline. If you want more control over
the media types and the pipeline you should use the more
low-level features of <application>GStreamer</application>.
