GStreamer is a pipeline-based multimedia framework written in the C programming language with the type system based on GObject.
GStreamer allows a programmer to create a 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, streaming media broadcasters, and media players.
Designed to be cross-platform, it is known to work on Linux (x86, PowerPC and ARM), Solaris (Intel and SPARC), Mac OS X, Microsoft Windows and OS/400. GStreamer has bindings for programming-languages like Python, C++, Perl, GNU Guile and Ruby. GStreamer is free software, licensed under the GNU Lesser General Public License.
Install the gstreamer package group: Template:Cli
GStreamer should already support PulseAudio for all applications since Template:Codeline is now a part of Template:Package Official, which itself is a part of Template:Codeline group mentioned in the previous section.
To avoid lots of dependencies, you may install this one instead.
After that be sure gstreamer is the first engine on the list under SystemSettings --> Multimedia --> Backend.
