<title>GStreamer</title>

GStreamer is a powerful multimedia library for playing, creating,

and manipulating sound, video, and other media.  You can use GStreamer

to provide sound and video playback, record input from multiple sources,

and edit multimedia content.  GStreamer supports encoding and decoding

numerous formats by default, and support for additional formats can be

added with plug-ins.

GStreamer provides a flexible architecture wherein media is

processed through a pipeline of elements.  Each element may apply

filters to the content, such as encoding or decoding, combining

multiple sources, or transforming the multimedia content.  This

architecture allows for an arbitrary arrangement of elements,

so that you can accomplish virtually any effect using GStreamer.

Furthermore, GStreamer is designed to have low overhead, so it

can be used in applications with high demands on latency.

While GStreamer provides a powerful API for manipulating

multimedia, it also provides convenient routines for simple

playback.  GStreamer can automatically construct a pipeline to

read and playback files in any supported format, allowing you

to use sound and video in your application easily.

The GStreamer architecture allows plugins to add encoders,

decoders, and all sorts of content filters.  Third-party developers

can provide GStreamer plugins which will be automatically available

to other applications using GStreamer.  Plugins can provide support

for other multimedia formats or provide additional functionality

and effects.

You should use GStreamer whenever you need to read or play

multimedia content in your application, or if your application

needs to manipulate sound or video.  Using GStreamer makes your

application development easy, and it provides you well-tested

elements for many of your needs.
