<part id="overview"><title>Overview</title>

<partintro>

<para>

<xref linkend="overview"/> gives you an overview of

|
<application>GStreamer</application> design goals.
|
|
|
|
<xref linkend="basic-concepts"/> rapidly covers the basics of
|
|
<application>GStreamer</application> programming.
|
|
|
|
In <xref linkend="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

|
|
type="http">GObject object model</ulink>.
|

For a gentle introduction to this system, you may wish to read the

<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.

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>.
