&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 audio
|
||
|
|
or video or both. It isn't restricted to audio and video, and can
|
||
|
|
process any kind of data flow.
|
||
|
|
The pipeline design is made to have little overhead above what the
|
||
|
|
applied filters induce. This makes &GStreamer; a good framework for
|
||
|
|
designing even high-end audio applications which put 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, MPEG-1/2, AVI, Quicktime, mod, and more. &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.
