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 (guile), and Ruby. GStreamer is free software, licensed under the GNU Lesser General Public License.

Installation

Install the gstreamer0.10-base package from the official repositories.

Integration

GStreamer should already support PulseAudio for all applications since gstreamer-pulse is now a part of gstreamer0.10-good-plugins.

To avoid lots of dependencies, you may choose to install gstreamer0.10-good-plugins-slimAUR from the AUR instead.

If you use KDE (and thus, phonon), you can easily install the GStreamer backend: phonon-gstreamer. After installation, be sure gstreamer is the first engine on the list under SystemSettings --> Multimedia --> Backend.

Lightweight desktop users: to configure GStreamer, for example to change the audio output device, use gstreamer-properties from package gnome-media. 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.

Hardware Acceleration

For hardware acceleration on VAAPI (Intel) hardware, install gstreamer-vaapiAUR.

More information on hardware acceleration can be found at Hardware Accelerated Video Decoding

Bugs

In case of error GStreamer-CRITICAL **: gst_mini_object_unref: assertion `mini_object->refcount > 0' failed which usually occurs when recording video through recording software, install gstreamer0.10-ffmpeg to fix.
