GStreamer is a multimedia framework written in the C programming language with the type system based on GObject. GStreamer serves a host of multimedia applications, such as video editors, streaming media broadcasters, and media players. Designed to be cross-platform, it is known to work on Linux (x86, PowerPC and ARM), Solaris (x86 and SPARC), Mac OS X, Microsoft Windows and OS/400. GStreamer is free software, licensed under the GNU Lesser General Public License. Image File history File links Gstreamer-logo. ...

History and development The project was founded in 1999 by Erik Walthinsen and had many of its core design ideas taken from a research project at University of Oregon. Wim Taymans joined the project soon thereafter and greatly expanded on many aspects of the system. Many others around the world have contributed to various degrees since then. The GStreamer logo was designed by Brock A. Frazier, working for an embedded Linux company called RidgeRun, which also was the first corporate sponsor of GStreamer in the form of hiring Erik Walthinsen to develop methods for embedding GStreamer in smaller (cell phone-class) devices. The University of Oregon is a public university located in Eugene, Oregon. ...

The diagram to the right could be an example of playing an MP3 file using GStreamer. The file source reads an MP3 file from the computers hard drive and sends it to the MP3 decoder. The decoder decodes the file data and converts it into PCM samples which are sent to the ALSA sound driver. The ALSA sound driver sends the PCM sound samples to the computer's speakers. MPEG-1 Audio Layer 3, more commonly referred to as MP3, is an audio encoding format. ...

Plugins GStreamer uses a plugin architecture which makes most of GStreamer's functionality implemented as shared libraries. GStreamer’s base functionality contains functions for registering and loading plugins and for providing the fundamentals of all classes in the form of base classes. Plugin libraries are dynamically loaded to support a wide spectrum of codecs, container formats and input/output drivers.

| Plugin set name | Description | | Good | This package contains the GStreamer plugins from the "good" set, a set of good-quality plug-ins under the LGPL license.[1] or according to Gstreamer, "contains a set of well-supported plug-ins under our preferred license"[2] | | Bad | GStreamer Bad Plug-ins is a set of plug-ins that aren't up to par compared to the rest. They might be close to being good quality, but they're missing something - be it a good code review, some documentation, a set of tests, a real live maintainer, or some actual wide use.[3] | | Ugly | This packages contains plugins from the "ugly" set, a set of good-quality plug-ins that might pose distribution problems[4] | Within a distribution these plugins may be further grouped, for example in Ubuntu the "bad" and "ugly" set are grouped into the "Main" component and the "Multiverse" component.

Criticism GStreamer has been criticized by KDE developers for not offering a stable ABI that is guaranteed to be maintained for at least five years after KDE4 is released, which makes it unsuitable as the standard multimedia framework in KDE4 and could prevent its inclusion in the Linux Standard Base. This problem eventually led to the development of Phonon, a simplified multimedia framework for KDE4, which would provide wrappers for other multimedia frameworks, including GStreamer.[5] KDE (K Desktop Environment) (IPA: ) is a free software project which aims to be a powerful system for an easy-to-use desktop environment. ...
