=== Enabling Flash Plugin ===
 
Adobe offers several methods to install their 32-bit Flash Player 10.  In general, the YUM version is preferred, since it allows the player to be updated automatically through Fedora's normal update mechanism.  The YUM version simply installs the repository configuration files, after which you must install Flash Player.
 
To begin, refer to the Adobe site at http://get.adobe.com/flashplayer/.  Select ''YUM for Linux'' to download, and confirm.
 
==== For i386 ====
 
After installing the repository configuration, run the following command:
 
<pre>
su -c 'yum install flash-plugin alsa-plugins-pulseaudio'
</pre>
 
You must authorize Adobe's key to complete the installation.  You may see a message indicating that <code>alsa-plugins-pulseaudio</code> is already installed.  This is not a problem.  After the installation, exit all copies of '''Firefox''' to enable the plugin.

At the time of this release, Adobe has an alpha version of a 64-bit player.  These instructions cover installation of the 32-bit player on a 64-bit (x86_64) platform.

This page contains information on Flash, a proprietary format for delivering audio and video content, primarily over the Internet.

Flash is non-free/proprietary software

Adobe's Flash plugin cannot be included in Fedora because it is not free/libre and open source software. Adobe does release a version of the Flash plugin for Linux, and this can be used in Firefox, Konqueror and other popular Internet browsers. When Adobe releases a newer version of the Linux Flash plugin, it makes packages available for Fedora, but Fedora cannot include Adobe's plugin as long as it is unavailable as free and open source software.

There are other open alternatives to Flash itself, including the patent unencumbered and free WebM, Ogg Theora video and Ogg Vorbis audio formats. Fedora has complete support for such open formats, and Fedora includes several web browsers including Firefox, Epiphany etc that plays Ogg and WebM files directly, without any need of third party and proprietary browser plugins.

YouTube, Vimeo and WebM support

Google has open sourced an implementation of VP8 video format and combined it with Ogg Vorbis audio and an adaptation of the Matroska container, creating a new format for free and open video and audio called WebM. YouTube is switching over to using WebM extensively and Fedora has embraced this format as well. Current versions of Fedora support WebM by default.

The Vimeo videoportal makes intensive use of javascript, and can in most cases be accessed without the need for Flash.

Youtube will automatically forward your Webbrowser to the right version, where no flash is needed if Flash is not installed on your system. Vimeo does that even more often, even if a flash player is installed.

Note that not all videos are available in WebM, or an open webmedia format yet, but the majority of them should play just fine.
