[GStreamer | http://freedesktop.org/Software/gstreamer] is an [LGPL]ed media framework for building graphs of inputs, filters, and outputs (think !DirectShow if you know it), based on the [GLib] 2.0 object model.

Inputs can be drivers for [DigitalCamera]s other other periphery, or may read media files, or get their input from basically anything else, such as network connections or by programmatically generating sound. Filters process their input in various ways; some of them are basically mandatory (like demultiplexers for a media file input stream), while others are others optional, such as sound enhancing filters or video effects. Outputs are could be drivers such as for sound output using [ALSA], [OSS|OpenSoundSystem], ESound, or anything else supported by the platform in question, or for video output using [X11], [OpenGL], or what have you, or they could push their input across a network connection or write it into a file or simply analyze it or whatever.

By using such an architecture, [MediaPlayer]s such as [Totem] as well as any other kinds of applications can take advantage of advances in CoDec and filter technology transparently. Developers can add new [CoDec]s to all [GStreamer]-based applications and filters by writing a simple plugin with a clean, generic interface. Most of the existing plugins are licensed under [LGPL] just like the framework itself, so [GStreamer] is useful for commercial development.

The [GStreamer] project is currently moving under the umbrella of the FreeDesktop project.
