&GStreamer; is a framework for creating streaming media applications.
The fundamental design comes from the video pipeline at Oregon Graduate
Institute, as well as some ideas from DirectShow.

&GStreamer;'s development framework makes it possible to write any
type of streaming multimedia application. The &GStreamer; framework
is designed to make it easy to write applications that handle audio
or video or both. It isn't restricted to audio and video, and can
process any kind of data flow.
The pipeline design is made to have little overhead above what the

MP3, Ogg/Vorbis, MPEG-1/2, AVI, Quicktime, mod, and more. &GStreamer;,
however, is much more than just another media player. Its main advantages
are that the pluggable components can be mixed and matched into arbitrary
pipelines so that it's possible to write a full-fledged video or audio
editing application.

The framework is based on plugins that will provide the various codec
and other functionality. The plugins can be linked and arranged in
a pipeline. This pipeline defines the flow of the data. Pipelines can
also be edited with a GUI editor and saved as XML so that pipeline
libraries can be made with a minimum of effort.

In order to understand this manual, you will need to have a basic
understanding of the C language.
Since &GStreamer; adheres to the GObject programming model, this guide
also assumes that you understand the basics of <ulink type="http"
url="http://developer.gnome.org/doc/API/2.0/gobject/index.html">GObject</ulink>
programming.
You may also want to have a look
at Eric Harlow's book <emphasis>Developing Linux Applications with
GTK+ and GDK</emphasis>.

In addition you might want to read the &GstPWG; after this manual.

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

application programming. At the end of that chapter, you should be
able to build your own audio player using &GStreamer;
</para>
<para>
In <xref linkend="part-advanced"/>, we will move on to complicated
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>
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.
