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), macOS, Microsoft Windows and OS/400. GStreamer has bindings for programming-languages like Python, C++, Perl, GNU Guile (guile), and Ruby. GStreamer is free software, licensed under the GNU Lesser General Public License.


Install a GStreamer version from the official repositories:

To make GStreamer useful, install the plugins packages you require.

Current version plugins

Legacy version plugins

Tip: Install all of them at once as gstreamer0.10-plugins.



PulseAudio support is provided by good plugins packages.

Lightweight desktops

To configure GStreamer, for example to change the audio output device, use gstreamer-properties from package gstreamer-propertiesAUR. This can be run by each user or as root for all users. Per-user configuration files are under $HOME/.gconf/system/gstreamer and the global files are in /etc/gconf/gconf.xml.defaults.

KDE / Phonon integration

See Phonon.

Hardware acceleration

See Hardware video acceleration.

GStreamer will automatically detect and use the correct API [1]. Depending on your system you can install:

Note: Enabling VA-API support on computers with Intel GPUs may cause issues with thumbnailing of video files. See GNOME Files#Thumbnailing_not_working_for_video_files for details.


assertion 'mini_object->refcount > 0' failed

If you get an GStreamer-CRITICAL **: gst_mini_object_unref: assertion 'mini_object->refcount > 0' failed error (which usually occurs when recording video), you can install gstreamer0.10-ffmpeg to fix it.
