Fedora includes applications for assorted multimedia functions, including playback, recording, and editing.  Additional packages are available through the Fedora Package Collection software repository.  For additional information about multimedia in Fedora, refer to the Multimedia section of the Fedora Project website at http://fedoraproject.org/wiki/Multimedia.

The default installation of Fedora includes '''Rhythmbox''' and '''Totem''' for media playback.  Many other programs are available in the Fedora repositories, including the popular '''XMMS''' player and KDE's '''Amarok'''.  Both GNOME and KDE have a selection of players that can be used with a variety of formats.  Additional programs are available from third parties to handle other formats.

'''Totem''', the default movie player for GNOME, now has the ability to switch playback backends without recompilation or switching packages. To install the xine backend, use ''Add/Remove Software'' to install <code>totem-xine</code> or run the following command:
 
 
 
<pre>
 
su -c 'yum install totem-xine'
 
</pre>
 
 
 
To run '''Totem''' with the xine backend once:
 
 
 
<pre>
 
su -c 'totem-backend -b xine totem'
 
</pre>
 
 
 
To change the default backend to xine for the entire system:
 
 
 
<pre>
 
su -c 'totem-backend -b xine'
 
</pre>
 
 
 
While using the Xine backend, it is possible to temporarily use the GStreamer backend. To use the GStreamer backend, run the following command:
 
 
 
<pre>
 
su -c 'totem-backend -b gstreamer'
 
</pre>
 
 
 
=== Ogg and Xiph.Org foundation formats ===
 
 
 
Fedora includes complete support for the Ogg media container format and the Vorbis audio, Theora video, Speex audio, and FLAC lossless audio formats.  These freely-distributable formats are not encumbered by patent or license restrictions.  They provide powerful and flexible alternatives to more popular, restricted formats.  The Fedora Project encourages the use of open source formats in place of restricted ones.  For more information on these formats and how to use them, refer to:
 
 
 
*  Xiph.Org Foundation at http://www.xiph.org/
 
* http://fedoraproject.org/wiki/Multimedia/Xiph
 
 
 
=== MP3, DVD, and other excluded multimedia ===
 
 
 
Fedora cannot include support for MP3 or DVD video playback or recording.  The MP3 formats are patented, and the patent holders have not provided the necessary licenses.  DVD video formats are patented and equipped with an encryption scheme.  The patent holders have not provided the necessary licenses, and the code needed to decrypt CSS-encrypted discs may violate the Digital Millennium Copyright Act, a copyright law of the United States. Fedora also excludes other multimedia software due to patent, copyright, or license restrictions, including Adobe's Flash Player and Real Media's Real Player.  For more on this subject, please refer to http://fedoraproject.org/wiki/ForbiddenItems.
 
 
 
While other MP3 options may be available for Fedora, Fluendo now offers an MP3 plugin for GStreamer that has the related patents licensed for end users.  This plugin enables MP3 support in applications that use the GStreamer framework as a backend.  We cannot distribute this plugin in Fedora for licensing reasons, but it offers a new solution for an old problem.  For more information refer to these pages:

=== CD and DVD authoring and burning ===
 
 
 
Default installations of Fedora and the Desktop Live spin include a built-in feature for CD and DVD burning. Fedora includes a variety of other tools for easily creating and burning CDs and DVDs. Fedora includes graphical programs such as <code>brasero</code>, <code>gnomebaker</code>, and <code>k3b</code>. Console programs including <code>wodim</code>, <code>readom</code>, and <code>genisoimage</code>.  Graphical programs are found under ''Applications > Sound & Video''.
 
 
 
=== Screencasts ===
 
 
 
You can use Fedora to create and play back ''screencasts'', which are recorded desktop sessions, using open technologies.  Fedora includes <code>istanbul</code>, which creates screencasts using the Theora video format, and <code>byzanz</code>, which creates screencasts as animated GIF files.  You can play back these videos using one of several players included in Fedora.  This is the preferred way to submit screencasts to the Fedora Project for either developers or end-users.  For more comprehensive instructions, refer to the screencasting page:
 
 
 
* http://fedoraproject.org/wiki/ScreenCasting
 
 
 
=== Extended support through plugins ===
 
 
 
Most of the media players in Fedora support the use of plugins to add support for additional media formats and sound output systems.  Some use powerful backends such as the <code>gstreamer</code> package to handle media format support and sound output.  Fedora offers plugin packages for these backends and for individual applications, and third parties may offer additional plugins to add even greater capabilities.
 
 
 
=== Infrared remote support ===
 
 
 
A new graphical frontend to LIRC is provided by <code>gnome-lirc-properties</code>, making it easy to connect and configure infrared remote controls. LIRC is routinely used in multimedia applications to implement support for infrared remote controls, and using it in '''Rhythmbox''' and '''Totem''' should be as easy as plugging the remote receiver into your computer, then selecting ''[Auto-detect]'' in the ''Infrared Remote Control'' preferences.
 
 
 
If you had a previous setup with LIRC, it is recommended you regenerate the configuration files with <code>gnome-lirc-properties</code>. This is required so that a majority of applications work with your new setup.
 
 
 
Refer to the feature page for more information:

=== Glitch-free PulseAudio ===
 
 
 
The PulseAudio sound server has been rewritten to use timer-based audio scheduling instead of the traditional interrupt-driven approach. This is the approach that is taken by other systems such as Apple's CoreAudio and the Windows Vista audio subsystem.  The timer-based audio scheduling has a number of advantages, including reduced power consumption, minimization of drop-outs, and flexible adjustment of the latency for the needs of the application.
 
 
 
=== SELinux denials in Totem and other GStreamer applications ===
 
 
 
Users may experience SELinux denials while using Totem or other GStreamer applications to play multimedia content.  A message similar to the following may be seen in the SELinux Troubleshooting tool:
 
 
 
SELinux is preventing gst-install-plu from making the program stack executable.
 
 
 
This may occur when older versions of the Fluendo MP3 codecs are installed.  The solution is to install the latest version of the Fluendo MP3 decoder plugin, which does not require an executable stack.
