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  When Adobe releases a newer version of the Linux Flash plugin, it makes packages available for Fedora, but Fedora cannot include Adobe's plugin as long as it is unavailable as free and open source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

== Fedora 10 and 11 ==
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.
 
This section contains information relevant specifically to installation of Flash on Fedora 10 and Fedora 11 Preview or later.
 
=== Enabling Flash Plugin ===
 
Adobe offers several methods to install their 32-bit Flash 10 plugin.  In general, the YUM version is preferred, since it allows the plugin to be updated automatically through Fedora's normal update mechanism.  The YUM version simply installs the repository configuration files, after which you must install the Flash plugin separately.
 
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 \
    libcurl'
</pre>
 
You may see messages indicating that <code>alsa-plugins-pulseaudio</code> and <code>libcurl</code> are 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 ====
 
===32 bit wrapped version===
 
These instructions will install a 32-bit plugin that will work with the 64-bit browser by being "wrapped" with nspluginwrapper.
 
After installing the repository configuration, run the following command to install the Flash plugin and ensure sound is enabled.
 
For Fedora 10:
<pre>
su -c 'yum install flash-plugin nspluginwrapper.x86_64 \
    nspluginwrapper.i386 alsa-plugins-pulseaudio.i386 \
    libcurl.i386'
</pre>
 
For Fedora 11:
<pre>
su -c 'yum install flash-plugin nspluginwrapper.x86_64 \
    nspluginwrapper.i586 alsa-plugins-pulseaudio.i386 \
    libcurl.i586'
</pre>
 
You may see a message indicating that <code>nspluginwrapper.x86_64</code> is already installed.  This is not a problem.
 
===64 bit alpha===
 
Adobe also has an alpha version of a 64-bit plugin.  Until this is supported via yum, you will need to do the following:
 
* Download the .tar.gz version from Adobe.
* Use "gtar -xzvf" to extract libflashplayer.so and put it in:
:<code>/usr/lib64/mozilla/plugins/<code>
:Putting the file in  ~/.mozilla/plugins/ will intentionally not work with Firefox.
* Restart Firefox.  (This automatically runs mozilla-plugin-config, so there is no need to do that manually.)
 
=== Checking the plugin ===
 
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:
<pre>
about:plugins
</pre>
 
A section similar to the following should appear:
 
[[Image:Flash-check-2.png]]
 
This information tells you that the Adobe Flash plugin has been successfully installed.


=== SELinux problems ===
== YouTube and WebM support ==


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:
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.


<pre>
To enable support for it in YouTube, go to http://youtube.com/html5 and click on "Join the HTML5 Beta" link in the bottom of that page. Note that all videos are not available in WebM format yet especially videos that include advertisements but majority of them should play just fine.  [https://www.youtube.com/watch?v=ZkeLgjv9W08 Here] is a sample video for testing.
su -c 'setsebool -P allow_unconfined_nsplugin_transition=0'
</pre>


=== <code>libflashsupport</code> deprecated ===
== Flash plugin ==


The <code>libflashsupport</code> package is no longer needed with Flash 10 and has been removed from Fedora 10.  The Flash plugin now calls the appropriate 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 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.

To enable support for it in YouTube, go to http://youtube.com/html5 and click on "Join the HTML5 Beta" link in the bottom of that page. Note that all videos are not available in WebM format yet especially videos that include advertisements but majority of them should play just fine. Here is a sample video for testing.
