GStreamer

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.

Installation

Install the gstreamer package.

To make GStreamer useful, install the plugins packages you require. See official documentation for list of features in each plugin.

gst-libav - Libav-based plugin containing many decoders and encoders.
gst-plugins-bad - Plugins that need more quality, testing or documentation.
gst-plugins-base - Essential exemplary set of elements.
gst-plugins-good - Good-quality plugins under LGPL license.
gst-plugins-ugly - Good-quality plugins that might pose distribution problems.
gst-plugin-libde265^AUR - libde265 plugin (an open h.265 video codec implementation) for gstreamer.

Integration

PulseAudio

PulseAudio support is provided by the gst-plugins-good package.

KDE / Phonon integration

See Phonon.

Hardware video acceleration

See Hardware video acceleration.

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

gstreamer-vaapi for VA-API support.
gst-plugins-bad and nvidia-utils for NVDECODE/NVENCODE support.

Ignore driver whitelist

GStreamer uses a whitelist of VA-API drivers. To ignore the whitelist and allow support for other drivers like intel-media-driver, set GST_VAAPI_ALL_DRIVERS=1 as environment variable.
