|
|||
|
<p>As stated in the <a href="http://gstreamer.freedesktop.org/" class="external-link">GStreamer home page</a>: GStreamer is a library for constructing graphs of media-handling components. The applications it supports range from simple Ogg/Vorbis playback, audio/video streaming to complex audio (mixing) and video (non-linear editing) processing.</p>
|
|||
|
<p>Applications can take advantage of advances in codec and filter technology transparently. Developers can add new codecs and filters by writing a simple plugin with a clean, generic interface.</p>
|
|||
|
<p>GStreamer is released under the LGPL. The 0.10 series is API and ABI stable.</p></td>

# What is the GStreamer SDK?
|
|||
|
|
|||
|
GStreamer has sometimes proven to be difficult to understand, in part
|
|||
|
due to the complex nature of the data it manipulates (multimedia
|
|||
|
graphs), and in part due to it being a live framework which continuously
|
|||
|
evolves.
|
|||
|
|
|||
|
This SDK, essentially, does four things for you:
|
|||
|
|
|||
|
- Sticks to one particular version of GStreamer, so you do not have to
|
|||
|
worry about changing documentation and features being added or
|
|||
|
deprecated.
|
|||
|
- Provides a wide range of tutorials to get you up to speed as fast as
|
|||
|
possible.
|
|||
|
- Provides a “build system”, this is, instructions and tools to build
|
|||
|
your application from the source code. On Linux, this is more or
|
|||
|
less straightforward, but GStreamer support for other operating
|
|||
|
system has been historically more cumbersome. The SDK is also
|
|||
|
available on Windows and Mac OS X to ease building on these systems.
|
|||
|
- Provides a one-stop place for all documentation related to
|
|||
|
GStreamer, including the libraries it depends on.
|
|||
|
|
|||
|
# What is the difference between this site and the one at freedesktop?
|
|||
|
|
|||
|
The main and most important difference between these two sites is the
|
|||
|
SDK: while [gstreamer.com](http://gstreamer.com/) provides a binary
|
|||
|
ready for use for anyone interested in this
|
|||
|
framework, [gstreamer.freedesktop.org](http://gstreamer.freedesktop.org/) pursues
|
|||
|
other objectives:
|
|||
|
|
|||
|
- [gstreamer.freedesktop.org](http://gstreamer.freedesktop.org/) is
|
|||
|
the main vehicle for the GStreamer community members to communicate
|
|||
|
with each other and improve this framework. This site is oriented to
|
|||
|
developers contributing to both, the development of the framework
|
|||
|
itself and building multimedia applications.
|
|||
|
- In contrast, the objective
|
|||
|
of [gstreamer.com](http://gstreamer.com/) is facilitating the use
|
|||
|
of GStreamer by providing a stable version of this framework,
|
|||
|
pre-built and ready to use. People using this SDK are mainly
|
|||
|
interested in the use of GStreamer as a tool that will help them
|
|||
|
build multimedia applications.

|||

# What is the target audience?
|
|||
|
|
|||
|
This SDK is mainly intended for application developers wanting to add
|
|||
|
cross-platform multimedia capabilities to their programs.
|
|||
|
|
|||
|
Developers wanting to write their own plug-ins for GStreamer should
|
|||
|
already be familiar with the topics covered in this documentation, and
|
|||
|
should refer to the [GStreamer
|
|||
|
documentation](http://gstreamer.freedesktop.org/documentation/) (particularly,
|
|||
|
the plug-in writer's guide).
|
|||
|
|
|||
