From Wikipedia, "a codec is a device or computer program capable of encoding and/or decoding a digital data stream or signal."

In general, codecs are utilized by multimedia applications to encode or decode audio or video streams. In order to play encoded streams, users must ensure an appropriate codec is installed.

This article deals only with codecs and application backends; see List of applications/Multimedia for a list of media players (MPlayer, mpv and VLC are popular choices).


Playing multimedia content requires two components:

  • A capable media player
  • The appropriate codec

It is not always necessary to explicitly install codecs if you have installed a media player. For example, MPlayer pulls in a large number of codecs as dependencies, and also has codecs built in.

From http://www.gstreamer.net/:

GStreamer is a library for constructing graphs of media-handling components. The applications it supports range from simple Ogg/Vorbis playback, audio/video streaming to complex audio (mixing) and video (non-linear editing) processing.

Simply, GStreamer is a backend or framework utilized by many media applications. See GStreamer article.


From http://www.xine-project.org/about:

xine is a free (gpl-licensed) high-performance, portable and reusable multimedia playback engine. xine itself is a shared library with an easy to use, yet powerful API which is used by many applications for smooth video playback and video processing purposes.

As an alternative to GStreamer, many media players can be configured to utilize the xine backend provided by xine-lib.

Note that the xine project itself provides a capable video player, xine-ui.


libavcodec is part of the FFmpeg project. It includes a large number of video and audio codecs. The libavcodec codecs are included with media players such as MPlayer and VLC, so you may not need to install the ffmpeg package itself.

Tips and tricks

Install MPlayer binary codecs

Tango-go-next.pngThis article or section is a candidate for moving to MPlayer.Tango-go-next.png

Notes: Belongs there. (Discuss in Talk:Codecs and containers#)

As an ultimate solution, you can try to install MPlayer binary codecs.

If you are not able to play some files go to http://www.mplayerhq.hu/design7/dload.html, read the instructions and install the codec you need to play your files.

They can also be found in the codecs64AUR package.

No H264, mpg4 or Musepack (.mpc) in Totem Player

If you see the "The H264 plugin is missing" warning with Totem media player, install gst-libav.
