GStreamer is a pipeline based multimedia framework that links together a wide variety of media processing systems to complete complex workflows. For instance, GStreamer can be used to build a system that reads files in one format, processes them, and exports them in another. The formats and processes can be changed in a plug and play fashion. GStreamer supports a wide variety of media handling components, including simple audio playback, audio and video playback, recording, streaming and editing. The pipeline design serves as a base to create many types of multimedia applications such as video editors, transcoders, streaming media broadcasters and media players. It is designed to work on a variety of operating systems, e. Linux kernel based operating systems, the BSDs, Open. Solaris, Android, mac. OS, i. OS, Windows, OS4. GStreamer is free and open source software subject to the terms of the GNU Lesser General Public License LGPL5 and is being hosted at freedesktop. Distribution and adoptioneditThe GNOME desktop environment, a heavy user of GStreamer, has included GStreamer since GNOME version 2. GNOME and GTK applications to use it. Other projects also use or support it, such as the Chameleo media platform, the Phonon media framework and the Songbird media player. GStreamer also operates in embedded devices like the Jolla Phone, the Palm Pre,6Tizen and the Nokia 7. N8. 00, N8. 10, N9. N9 Internet Tablets running the Maemo operating system. In addition to source code releases, the GStreamer project provides binary builds for Android, i. OS, OSX and Windows.

GStreamer is a pipelinebased multimedia framework that links together a wide variety of media processing systems to complete complex workflows. Language bindingseditA library written in one programming language may be used in another language if bindings are written GStreamer has a range of bindings for various languages such as Python, Vala, C, Perl, GNU Guile, C and Ruby. OvervieweditGStreamer processes media by connecting a number of processing elements into a pipeline. Each element is provided by a plug in. Elements can be grouped into bins, which can be further aggregated, thus forming a hierarchical graph. This is an example of a filter graph. Elements communicate by means of pads. A source pad on one element can be connected to a sink pad on another. When the pipeline is in the playing state, data buffers flow from the source pad to the sink pad. Pads negotiate the kind of data that will be sent using capabilities. The diagram to the right could exemplify playing an MP3 file using GStreamer. The file source reads an MP3 file from a computers hard drive and sends it to the MP3 decoder. The decoder decodes the file data and converts it into PCM samples which then pass to the ALSA sound driver. The ALSA sound driver sends the PCM sound samples to the computers speakers. Plug inseditGStreamer uses a plug in architecture which makes the most of GStreamers functionality implemented as shared libraries. GStreamers base functionality contains functions for registering and loading plug ins and for providing the fundamentals of all classes in the form of base classes. Plug in libraries get dynamically loaded to support a wide spectrum of codecs, container formats, inputoutput drivers and effects. Plug ins can be installed semi automatically when they are first needed. For that purpose distributions can register a backend that resolves feature descriptions to package names. Since version 0. 9, the plug ins come grouped into three sets named after the film The Good, the Bad and the Ugly. Plug in set name. Description. Good. This package contains the GStreamer plug ins from the good set, a set of high quality plug ins under the LGPL license,1. Gstreamer, contains a set of well supported plug ins under our preferred license. Bad. GStreamer Bad Plug ins comprises a set of plug ins not up to par compared to the rest. They might closely approach good quality plug ins, but they lack something perhaps a good code review, some documentation, a set of tests, a real live maintainer, or some actual wide use. Ugly. This package contains plug ins from the ugly set, a set of poor quality plug ins that might pose distribution problems. Individual distributions may further sub classify these plug ins for example Ubuntu groups the bad and ugly sets into the Universe or the Multiverse components. Theres also a separate GStreamer FFmpeg plug in, which is a FFmpeg based plug in that supports many additional media formats. It was first released on 2. February 2. 00. 4, with version number 0. It can transparently use Libav, and as such is often called the GStreamer Libav plug in in recent Linux distributions. Video accelerationedit. Through special plugins provided by Texas Instruments, GStreamer makes use of hardware acceleration provided by e. Texas Instruments Da. Vinci. There are various SIP blocks that can do the computations to decode certain video codecs, such as Pure. Video, UVD, Quick. Sync Video, TI Ducati and more. Such needs to be supported by the device driver, which in turn provides one or multiple interfaces, like VDPAU, VAAPI, Distributed Codec Engine or DXVA to end user software like MPlayer to access this hardware and offload computation to it. Media formatseditThe Good, Bad and Ugly GStreamer plugins mentioned earlier provide, alongside processing elementsfilters of all kinds, support for a wide variety of file formats, protocols and multimedia codecs. In addition to those, support for more than a hundred compression formats including MPEG 1, MPEG 2, MPEG 4, H. H. 2. 63, H. 2. 64, Real. Video, MP3, WMV, FLV, etc. GStreamer FFmpeglibav plug in. See the Libav and FFmpeg pages for a complete list of media formats provided by these plug ins. History and developmenteditEarly dayseditErik Walthinsen founded the GStreamer project in 1. Many of its core design ideas came from a research project at the Oregon Graduate Institute. Wim Taymans joined the project soon thereafter and greatly expanded on many aspects of the system. Many other software developers have contributed since then. The first major release was 0. January 2. 00. 1. Not long after, GStreamer picked up its first commercial backer, an embedded Linux company called Ridge. Run. Towards the end of January 2. Picasa Web Viewer. Erik Walthinsen to develop methods for embedding GStreamer in smaller cell phone class devices. Another Ridge. Run employee, Brock A. Frazier, designed the GStreamer logo. Ridge. Run later struggled financially and had to lay off its staff, including Erik Walthinsen. GStreamer progress was mostly unaffected. The project released a series of major releases with 0. July 2. 00. 1, 0. September 2. 00. 2, and 0.
