Embed media in Ckeditor field for drupal 7
The standalone version of ckeditor module comes with a plugin called media embed. Ensure you have:


Enabled the media embed plugin for Ckeditor
Added the media embed input filter to a text format that your uses have access to (and is not filtered or tag limited in anyway)
Added the media embed button to the toolbar for the above text format


And that is it. In order to embed a youtube video (or anything for that matter), you get the &lt;iframe&gt; embed code from youtube, and paste it into the media embed dialog popup.
