=== 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. After installing the repository configuration, run the following command:
 
<pre>
su -c 'yum install flash-plugin'
</pre>
 
==== i386 dependencies ====
 
'''Alsa''' must be installed to get sound from the Flash plugin:
 
<pre>
su -c 'yum install alsa-plugins-pulseaudio'
</pre>
 
You may see a message indicating that <code>alsa-plugins-pulseaudio</code> is already installed.  This is not a problem.
 
Note that <code>nspluginwrapper</code> probably already is installed and will wrap the Flash plugin.
 
==== X86_64 dependencies ====
 
These instructions cover installation of the 32-bit player on a 64-bit (x86_64) platform. (At the time of this release, Adobe also has an alpha version of a 64-bit player.)
 
'''nspluginwrapper''' must be installed to wrap the 32-bit plugin as if it was a 64-bit plugin in the 64-bit '''Firefox'''.
 
<pre>
su -c 'yum install nspluginwrapper.x86_64 nspluginwrapper.i386 \
    alsa-plugins-pulseaudio.i386'
</pre>
 
You will probably see a message indicating that <code>nspluginwrapper.x86_64</code> is already installed.  This is not a problem.
 
==== Restarting Firefox ====
 
After the installation, exit all copies of '''Firefox''' and start it again to enable the plugin.
 
=== Checking the plugin ===


Type the following text in the Firefox address bar:

A section similar to the following should appear:

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 ==


This information tells you that Adobe Flash Player has been successfully installed.
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.  


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


In some cases, <code>nspluginwrapper</code> produces SELinux AVC errors, some of which may prevent viewing Flash content. Changing the relevant SELinux boolean may resolve this problem, but eliminates a great deal of additional security when using <code>nspluginwrapper</code>. To make the change, run the following command:
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.

For information on installing the plugin, refer to [https://ask.fedoraproject.org/en/question/10217/ Ask Fedora Flash page]


The Flash plugin now calls <code>alsa</code> directly, and in the default configuration alsa will hand it over to <code>pulseaudio</code>.

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.

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

Flash plugin
