=== 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.
 
Then proceed to either the instructions for [[#For_i386 | 32-bit (i386) platforms]] or [[#For_x86_64 | 64-bit (x86_64) platforms]].
 
==== For i386 ====
 
After installing the repository configuration, run the following command to install the Flash plugin and ensure sound is enabled:
<pre>
su -c 'yum install flash-plugin 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 also that <code>nspluginwrapper</code> is already installed by default and will wrap the Flash plugin.
 
Next, you should [[#Checking_the_plugin | check the plugin]].
 
==== For x86_64 ====
 
{{Admon/note | Adobe Flash 64-bit alpha | At the time of this release, Adobe also has an alpha version of a 64-bit player.  When that product is more mature, these instructions will cover its use.}}
 
After installing the repository configuration, run the following command to install the Flash plugin and ensure sound is enabled:
<pre>
su -c 'yum install flash-plugin nspluginwrapper.x86_64 \
    nspluginwrapper.i386 alsa-plugins-pulseaudio.i386'
</pre>
 
You may see a message indicating that <code>nspluginwrapper.x86_64</code> is already installed.  This is not a problem.


=== Checking the plugin ===
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  When Adobe releases a newer version of the Linux Flash plugin, it makes packages available for Fedora, but Fedora cannot include Adobe's plugin as long as it is unavailable as free and open source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.


After the installation, exit all copies of '''Firefox''' and start it again to enable the plugin. Then type the following text in the Firefox address bar:
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.

A section similar to the following should appear:
== YouTube, Vimeo and WebM support ==


[[Image:Flash-check-2.png]]
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.  


This information tells you that Adobe Flash Player has been successfully installed.
The Vimeo videoportal makes intensive use of javascript, and can in most cases be accessed without the need for Flash.


=== SELinux problems ===
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.


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:

su -c 'setsebool -P allow_unconfined_nsplugin_transition=0'
</pre>


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


The <code>libflashsupport</code> package is no longer needed with Flash 10 and has been removed from Fedora 10.  The Flash plugin now calls ALSA functions directly, and in the default configuration ALSA delivers sound to PulseAudio.

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.
