+ A bin is a container element. You can add elements to a bin. Since a bin is
+ an element itself, it can also be added to another bin.
+ </para>

+ Bins allow you to combine a group of linked elements into one logical element. You do

+ We will see that this is extremely powerful when you are going to construct

+ <para>
+ When the thread is saved, the object_save method will be called. Our example

+}
+ </programlisting>
+ <para>
+ Adding the custom tag code to the above example you will get an XML file
+ with the custom tags in it. Here's an excerpt:
+ </para>
+ <programlisting>
+ ...
+ <gst:element>
+ <gst:name>thread</gst:name>
+ <gst:type>thread</gst:type>

+ <test:text>decoder thread</test:text>
+ </test:comment>
+ </gst:element>
+ ...
+ </programlisting>
+ <para>
+ To retrieve the custom XML again, you need to attach a signal to
+ the GstXML object used to load the XML data. You can then parse your
+ custom XML from the XML tree whenever an object is loaded.
+ </para>
+
+ <para>
+ We can extend our previous example with the following piece of
+ code.
+ </para>
+
+ <programlisting>
+ xml = gst_xml_new ();

+ ret = gst_xml_parse_file (xml, "xmlTest.gst", NULL);
+ g_assert (ret == TRUE);
+ </programlisting>
+
+ <para>
+ Whenever a new object has been loaded, the xml_loaded function will
+ be called. This function looks like:
+ </para>
+ <programlisting>
+static void
+xml_loaded (GstXML *xml, GstObject *object, xmlNodePtr self, gpointer data)
+{
+ xmlNodePtr children = self->xmlChildrenNode;

+ }
+ nodes = nodes->next;
+ }
+ }
+ children = children->next;
+ }
+}
+ </programlisting>
+ <para>
+ As you can see, you'll get a handle to the GstXML object, the
+ newly loaded GstObject and the xmlNodePtr that was used to create
+ this object. In the above example we look for our special tag inside
+ the XML tree that was used to load the object and we print our

+ 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
+ applied filters induce. This makes GStreamer a good framework for designing
+ even high-end audio applications which put high demands on latency.
+ </para>
+
+ <para>
+ One of the the most obvious uses of GStreamer is using it to build
+ a media player. GStreamer already includes components for building a
+ media player that can support a very wide variety of formats, including
+ MP3, Ogg Vorbis, MPEG1, MPEG2, 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.
+ </para>
+
+ <para>
+ 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.
+ </para>
+
+ <para>
+ The GStreamer core function is to provide a framework for plugins, data flow
+ and media type handling/negotiation.
+ It also provides an API to write applications using the various plugins.
+ </para>
+
+ <para>
+ This book is about GStreamer from a 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 Plugin Writers Guide.
