<title>What is GStreamer?</title>
|

<para>

|
GStreamer is a framework for creating streaming media applications.
|
|
The fundamental design comes from the video pipeline at Oregon Graduate
|
|
Institute, as well as some ideas from DirectShow.

GStreamer's development framework makes it possible to write any type of
|
|
streaming multimedia application. The GStreamer framework is designed to make it easy to
|
|
write applications that handle either audio or video or both. The pipeline design is made to have
|
|
no extra overhead above what the applied filters induce. This makes GStreamer a good framework for designing
|
|
even high-end audio applications which puts high demands on latency.

One of the the most obvious uses of GStreamer is using it to build
|
|
a media player. GStreamer already includes components for building a
|
|
media player that can support a very wide variety of formats, including
|
|
MP3, Ogg Vorbis, MPEG1, MPEG2, AVI, Quicktime, mod and so on. GStreamer,
|
|
however, is much more than just another media player. Its main advantages
|
|
are that the pluggable components can be mixed and matched into arbitrary
|
|
pipelines so that it's possible to write a full-fledged video or audio
|
|
editing application.

The framework is based on plugins that will provide the various codec
|
|
and other functionality. The plugins can be linked and arranged in
|
|
a pipeline. This pipeline defines the flow of the data. Pipelines can
|
|
also be edited with a GUI editor and saved as XML so that pipeline
|
|
libraries can be made with a minimum of effort.

|
|
The GStreamer core function is to provide a framework for plugins, data flow
|
|
and media type handling/negotiation.
|
|
It also provides an API to write applications using the various plugins.

This book is about GStreamer from a developer's point of view; it describes
|
|
how to write a GStreamer application using the GStreamer libraries and tools.
|
|
For an explanation about writing plugins, we suggest the Plugin Writers Guide.
