<para>
Extensions to GStreamer can be made using a plugin mechanism. This is
used extensively in GStreamer even if only the standard package is
being used: a few very basic functions reside in the core library, and
all others are in a standard set of plugins.
</para>
<para>
Plugins are only loaded when needed: a plugin registry is used to
store the details of the plugins so that it is not neccessary to load
all plugins to determine which are needed.
This registry needs to be updated when a new plugin is added to the

<title>Elements</title>
<para>
Elements are at the core of GStreamer. Without elements, GStreamer is just

elements (filters, sources and sinks) ship with GStreamer, but extra
elements can also be written.

An element may be constructed in several different ways, but all must
conform to the same basic rules. A simple filter may be built with the
FilterFactory, where the only code that need be written is the actual
filter code. A more complex filter, or a source or sink, will need to be
written out fully for complete access to the features and performance
possible with GStreamer.

<title>Constructing the boilerplate</title>

The first thing to do when making a new element is to specify some basic
details about it: what its name is, who wrote it, what version number it
is, etc. We also need to define an object to represent the element and to
store the data the element needs. I shall refer to these details
collectively as the <emphasis>boilerplate</emphasis>.

<title>Buffers</title>
<para>
Buffers are structures used to pass data between elements. All streams
of data are chopped up into chunks which are stored in buffers.
Buffers can be of any size, and also contain metadata indicating the
type of data contained in them. Buffers can be allocated by various
different schemes, and may either be passed on by elements or
unreferenced (and the memory used by the buffer freed).
</para>

<title>Typing and Properties</title>
<para>
A type system is used to ensure that the data passed between elements
is in a recognised format, and that the various parameters required
to fully specify that format match up correctly. Each connection
that is made between elements has a specified type. This is related,
but different, to the metadata in buffers which describes the type
of data in that particular buffer. See later in this document for
details of the available types.

<title>Autopluggers</title>
<para>
&GStreamer; has an autoplugging mechanism, which enables application
writers to simply specify start and end elements for a path, and
the system will then create a path which links these elements,
in accordance with the type information provided by the elements.
</para>
<para>
It is possible to devise many different schemes for generating such
pathways, perhaps to optimise based on special criteria, or with
some specific constraints. It is thus possible to define new
autoplugging systems, using the plugin system.
</para>
</chapter>
</part>
<!-- ############ part ############# -->
<part id="typesnprops"><title>Types and Properties</title>
<partintro>
<para>
There is a very large set of possible types that may be used to
pass data between elements. Indeed, each new element that is defined
may use a new data format (though unless at least one other element
recognises that format, it will be most likely be useless since
nothing will be able to link with it).
</para>
<para>
In order for types to be useful, and for systems like autopluggers to
work, it is neccessary that all elements
agree on the type definitions, and which properties are required
for each type. The &GStreamer; framework itself
simply provides the ability to define types and parameters, but does
not fix the meaning of types and parameters, and does not enforce
standards on the creation of new types. This is a matter for
a policy to decide, not technical systems to enforce.
</para>
<para>
For now, the policy is simple:
<itemizedlist>
<listitem>
<para>
Do not create a new type if you could use one which already
exists.
</para>
</listitem>
<listitem>
<para>
If creating a new type, discuss it first with the other
&GStreamer; developers, on at least one of: IRC, mailing lists,
the &GStreamer; wiki.
</para>
</listitem>
<listitem>
<para>
Try to ensure that the name for a new format is as unlikely to
conflict with anything else created already, and is not a more
generalised name than it should be. For example:
"audio/compressed" would be too generalised a name to represent
audio data compressed with an mp3 codec. Instead "audio/mp3"
might be an appropriate name, or "audio/compressed" could exist
and have a property indicating the type of compression used.
</para>
</listitem>
<listitem>
<para>
Ensure that, when you do create a new type, you specify it
clearly, and get it added to the list of known types so that
other developers can use the type correctly when writing their
elements.
</para>
</listitem>
</itemizedlist>

</partintro>
<chapter id="cha-basic-types">

Each element has two functions which are used for construction of
an element. These are the _class_init() function, which is used to
initialise the class (specifying what signals and arguments the class
has and setting up global state), and the _init() function, which
is used to initialise a specific instance of the class.

<title>Defining a type</title>

A new type is defined by creating an type factory. This is a
structure containing all the information needed to create an instance
of the type.

<chapter id="cha-plugininit">
<title>The plugin_init function</title>
<para>
Once we have written code defining all the parts of the plugin,
we need to write the plugin_init() function. This is a special
function, which is called as soon as the plugin is loaded, and
must return a pointer to a newly allocated GstPlugin structure.
This structure contains the details of all the facilities provided
by the plugin, and is the mechanism by which the definitions are
made available to the rest of the &GStreamer; system. Helper
functions are provided to help fill the
structure: for future compatability it is recommended that these
functions are used, as documented below, rather than attempting to
access the structure directly.
</para>
<para>
Note that the information returned by the plugin_init() function
will be cached in a central registry. For this reason, it is
important that the same information is always returned by
the function: for example, it must not make element factories
available based on runtime conditions. If an element can only
work in certain conditions (for example, if the soundcard is not
being used by some other process) this must be reflected by the
element being unable to enter the READY state if unavailable, rather
than the plugin attempting to deny existence of the plugin.

<title>Adding custom XML tags into the core XML data</title>
<para>
It is possible to add custom XML tags to the core XML created with
gst_xml_write. This feature can be used by an application to add more
information to the save plugins. the editor will for example insert
the position of the elements on the screen using the custom XML tags.
</para>
<para>
It is strongly suggested to save and load the custom XML tags using
a namespace. This will solve the problem of having your XML tags
interfere with the core XML tags.
</para>
<para>
To insert a hook into the element saving procedure you can connect
a signal to the GstElement using the following piece of code:
</para>
<programlisting>
xmlNsPtr ns;
...
ns = xmlNewNs (NULL, "http://gstreamer.net/gst-test/1.0/", "test");
...
thread = gst_elementfactory_make("thread", "thread");
gtk_signal_connect (GTK_OBJECT (thread), "object_saved", object_saved, g_strdup ("decoder thread"));
...
</programlisting>
<para>
When the thread is saved, the object_save method will be caled. Our example
will insert a comment tag:
</para>
<programlisting>
static void
object_saved (GstObject *object, xmlNodePtr parent, gpointer data)
{
xmlNodePtr child;
child = xmlNewChild(parent, ns, "comment", NULL);
xmlNewChild(child, ns, "text", (gchar *)data);
}
</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>
...
&lt;gst:element&gt;
&lt;gst:name&gt;thread&lt;/gst:name&gt;
&lt;gst:type&gt;thread&lt;/gst:type&gt;
&lt;gst:version&gt;0.1.0&lt;/gst:version&gt;
...
&lt;/gst:children&gt;
&lt;test:comment&gt;
&lt;test:text&gt;decoder thread&lt;/test:text&gt;
&lt;/test:comment&gt;
&lt;/gst:element&gt;
...
</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 ();
gtk_signal_connect (GTK_OBJECT (xml), "object_loaded", xml_loaded, xml);
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-&gt;xmlChildrenNode;
while (children) {
if (!strcmp (children-&gt;name, "comment")) {
xmlNodePtr nodes = children-&gt;xmlChildrenNode;
while (nodes) {
if (!strcmp (nodes-&gt;name, "text")) {
gchar *name = g_strdup (xmlNodeGetContent (nodes));
g_print ("object %s loaded with comment '%s'\n",
gst_object_get_name (object), name);
}
nodes = nodes-&gt;next;
}
}
children = children-&gt;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
comment to the console.
