This chapter will summarize everything you've learned in the previous
chapters. It describes all aspects of a simple &GStreamer; application,
including initializing libraries, creating elements, packing elements
together in a pipeline and playing this pipeline. By doing all this,
you will be able to build a simple Ogg/Vorbis audio player.

We're going to create a simple first application, a simple Ogg/Vorbis
command-line audio player. For this, we will use only standard
&GStreamer; components. The player will read a file specified on
the command-line. Let's get started!
</para>
<para>
We've learned, in <xref linkend="chapter-init"/>, that the first thing
to do in your application is to initialize &GStreamer; by calling
<function>gst_init ()</function>. Also, make sure that the application
includes <filename>gst/gst.h</filename> so all function names and
objects are properly defined. Use <function>#include
&lt;gst/gst.h&gt;</function> to do that.
</para>
<para>
Next, you'll want to create the different elements using
<function>gst_element_factory_make ()</function>. For an Ogg/Vorbis
audio player, we'll need a source element that reads files from a
disk. &GStreamer; includes this element under the name
<quote>filesrc</quote>. Next, we'll need something to parse the
file and decode it into raw audio. &GStreamer; has two elements

for this: the first parses Ogg streams into elementary streams (video,
audio) and is called <quote>oggdemux</quote>. The second is a Vorbis
audio decoder, it's conveniently called <quote>vorbisdec</quote>.
Since <quote>oggdemux</quote> creates dynamic pads for each elementary
stream, you'll need to set a <quote>pad-added</quote> event handler

The last thing left to do is to add all elements into a container
element, a <classname>GstPipeline</classname>, and iterate this
pipeline until we've played the whole song. We've previously
learned how to add elements to a container bin in <xref
linkend="chapter-bins"/>, and we've learned about element states
in <xref linkend="section-elements-states"/>. We will also attach
a message handler to the pipeline bus so we can retrieve errors
and detect the end-of-stream.

<title>Compiling and Running helloworld.c</title>
<para>
To compile the helloworld example, use: <command>gcc -Wall
$(pkg-config --cflags --libs gstreamer-&GST_MAJORMINOR;)
helloworld.c -o helloworld</command>. &GStreamer; makes use of
<command>pkg-config</command> to get compiler and linker flags
needed to compile this application.
</para>
<para>
If you're running a non-standard installation (ie. you've installed
GStreamer from source yourself instead of using pre-built packages),
make sure the <classname>PKG_CONFIG_PATH</classname> environment variable
is set to the correct location (<filename>$libdir/pkgconfig</filename>).
</para>
<para>
In the unlikely case that you are using an uninstalled GStreamer
setup (ie. gst-uninstalled), you will need to use libtool to build the
hello world program, like this: <command>libtool --mode=link gcc -Wall
$(pkg-config --cflags --libs gstreamer-&GST_MAJORMINOR;)
helloworld.c -o helloworld</command>.

This concludes our first example. As you see, setting up a pipeline
is very low-level but powerful. You will see later in this manual how

you can create a more powerful media player with even less effort
using higher-level interfaces. We will discuss all that in <xref

into more advanced &GStreamer; internals.

It should be clear from the example that we can very easily replace
the <quote>filesrc</quote> element with some other element that
reads data from a network, or some other data source element that
is better integrated with your desktop environment. Also, you can
use other decoders and parsers/demuxers to support other media types. You

can use another audio sink if you're not running Linux, but Mac OS X,
Windows or FreeBSD, or you can instead use a filesink to write audio
files to disk instead of playing them back. By using an audio card
source, you can even do audio capture instead of playback. All this
shows the reusability of &GStreamer; elements, which is its greatest
advantage.
