This demo shows the viral videos plugin in its default configuration.
The only configuration option we have added here is a description text that will be used when the user shares the page link to social sites.
HTML meta tags to share the player
When you share this page on certain social networks like Facebook, not only a link back to this page is shared but also the player. This viral spreading of the media itself is achieved by adding HTML meta attributes to your page.
Here are the HTML tags and attributes needed to share this page with the player:
Most of the above tags are self-explanatory. Some of them, like
og:title, may be used
to override a page attribute for more specific use in media sharing.
We have two groups of meta tags with overlapping content. A network like MySpace needs the group which is labeled 'old-fashioned', while Facebook and others prefer the Open Graph protocol.
For Facebook and Open Graph it is recommended that you add these schemas to the

Video meta tags
The tags responsible for sharing the player are:
og:video:secure_url. Their value is an URL pointing to the location of the
Flowplayer swf file with a query containing the player configuration:
Shared players are embedded by social networks using an OBJECT tag. The configuration
part therefore is formatted the same way as the
flashvars parameter of the
object tag and
must then be url-encoded as it is the query part of an URL.
Ensure that the URLs of the Flowplayer assets (logo, plugins etc.) in the configuration of the
og:video:secure_url tag resolve to a
HTTPS location. Using
HTTPS for all video locations
We recommend using an external configuration file because url-encoding even
a simple configuration is error-prone and hard to maintain. As you can only share one player
per page anyway - albeit from various locations - this is much easier as long as you stick
to a consistent naming scheme. Often the shared configuration will vary slightly from the
configuration of the player on the originating page, and then again a human-readable
configuration is easier to set up - as in this demo. Note however, that the
external configuration file used for sharing must be served from the same domain as the core
Debugging meta tags
Check the meta tags of your page in Facebook's Debugger.
Try the value of the video meta tags in action by entering them in your browser's location bar.
For this page just click on the following link which is the value of
