<title>Plugins</title>
|
|
<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
|
|
system: see the <emphasis>gstreamer-register</emphasis> utility and the
|
|
documentation in the <emphasis>GStreamer Application Development
|
|
Manual</emphasis> for more details.
|
|
</para>
|
|
<para>
|
|
User extensions to GStreamer can be installed in the main plugin
|
|
directory, and will immediately be available for use in applications.
|
|
<emphasis>gstreamer-register</emphasis> should be run to update
|
|
the repository: but the system will work correctly even if it hasn't
|
|
been - it will just load the correct plugin faster.
|
|
</para>
|
|
<para>
|
|
User specific plugin directories and registries will be available in future
|
|
versions of GStreamer.

<title>Elements</title>
|
|
<para>
|
|
Elements are at the core of GStreamer. Without elements, GStreamer is just
|
|
a bunch of pipe fittings with nothing to connect. A large number of
|
|
elements (filters, sources and sinks) ship with GStreamer, but extra
|
|
elements can also be written.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
The implementation of a new element will be contained in a plugin:
|
|
a single plugin may contain the implementation of several elements, or
|
|
just a single one.
