# GStreamer Editing Services
The "GStreamer Editing Services" is a library to simplify the creation
of multimedia editing applications. Based on the GStreamer multimedia framework
and the GNonLin set of plugins, its goals are to suit all types of editing-related
applications.
The GStreamer Editing Services are cross-platform and work on most UNIX-like
platform as well as Windows. It is released under the GNU Library General Public License
(GNU LGPL).
## Goals of GStreamer Editing Services
The GStreamer multimedia framework and the accompanying GNonLin set of
plugins for non-linear editing offer all the building blocks for:
- Decoding and encoding to a wide variety of formats, through all the
available GStreamer plugins.
- Easily choosing segments of streams and arranging them through time
through the GNonLin set of plugins.
But all those building blocks only offer stream-level access, which
results in developers who want to write non-linear editors to write a
consequent amount of code to get to the level of *non-linear editing*
notions which are closer and more meaningful for the end-user (and
therefore the application).
The GStreamer Editing Services (hereafter GES) aims to fill the gap
between GStreamer/GNonLin and the application developer by offering a
series of classes to simplify the creation of many kind of
editing-related applications.
## Architecture
### Timeline and TimelinePipeline
The most top-level object encapsulating every other object is the
[GESTimeline](GESTimeline). It is the central object for any editing project.
The `GESTimeline` is a `GstElement`. It can therefore be used in any
GStreamer pipeline like any other object.
### Tracks and Layers
The GESTimeline can contain two types of objects (seen in
"Layers and Tracks"):
- Layers - Corresponds to the user-visible arrangement of clips, and
what you primarily interact with as an application developer. A
minimalistic timeline would only have one layer, but a more complex
editing application could use as many as needed.
- Tracks - Corresponds to the output streams in GStreamer. A typical
GESTimeline, aimed at a video editing application, would have an
audio track and a video track. A GESTimeline for an audio editing
application would only require an audio track. Multiple layers can
be related to each track.
![Layers and Tracks](images/layer_track_overview.png)
In order to reduce even more the amount of GStreamer interaction the
application developer has to deal with, a convenience GstPipeline has
been made available specifically for Timelines : [GESPipeline](GESPipeline).

<title>Goals of GStreamer Editing Services</title>
<para>The GStreamer multimedia framework and the accompanying GNonLin set
of plugins for non-linear editing offer all the building blocks for:
<itemizedlist>
<listitem>
<para>Decoding and encoding to a wide variety of formats, through
all the available GStreamer plugins.</para>
</listitem>
<listitem>
<para>Easily choosing segments of streams and arranging them through
time through the GNonLin set of plugins.</para>
</listitem>
</itemizedlist></para>
<para>But all those building blocks only offer stream-level access, which
results in developers who want to write non-linear editors to write a
consequent amount of code to get to the level of <emphasis>non-linear
editing</emphasis> notions which are closer and more meaningful for the
end-user (and therefore the application).</para>
<para>The GStreamer Editing Services <remark>(hereafter GES)</remark> aims
to fill the gap between GStreamer/GNonLin and the application developer by
offering a series of classes to simplify the creation of many kind of
editing-related applications.</para>
</refsect1>
<refsect1>
<title>Architecture</title>
<refsect2>
<title>Timeline and TimelinePipeline</title>
<para>The most top-level object encapsulating every other object is the
<link linkend="GESTimeline">GESTimeline</link>. It is the central object
for any editing project.</para>
<para>The <classname>GESTimeline</classname> is a
<classname>GstElement</classname>. It can therefore be used in any
GStreamer pipeline like any other object.</para>
</refsect2>
<refsect2>
<title>Tracks and Layers</title>
<para>The GESTimeline can contain two types of objects (seen in <xref
linkend="layer_tracks_diagram" />): <itemizedlist>
<listitem>
<para>Layers - Corresponds to the user-visible arrangement of clips,
and what you primarily interact with as an application developer.
A minimalistic timeline would only have one layer,
but a more complex editing application could use as many as needed.
</para>
</listitem>
<listitem>
<para>Tracks - Corresponds to the output streams in GStreamer.
A typical GESTimeline, aimed at a video editing application, would
have an audio track and a video track.
A GESTimeline for an audio editing application would only require
an audio track. Multiple layers can be related to each track.</para>
</listitem>
</itemizedlist></para>

<para>In order to reduce even more the amount of GStreamer interaction
the application developer has to deal with, a convenience GstPipeline
has been made available specifically for Timelines : <link

<title>GStreamer Editing Services Overview</title>
<para>
The "GStreamer Editing Services" is a library to simplify the creation
of multimedia editing applications. Based on the GStreamer multimedia framework
and the GNonLin set of plugins, its goals are to suit all types of editing-related
applications.
</para>
<para>
The GStreamer Editing Services are cross-platform and work on most UNIX-like
platform as well as Windows. It is released under the GNU Library General Public License
(GNU LGPL).
