NCAM/ccFlash: &quot;Advanced&quot; captions - can be styled, colour, position. “ Aaron” player: OpenLaszlo-based – free software, potential. accessibility patch submitted. http://aaronwinborn.com . “ Aaron” player: OpenLaszlo/ Drupal – lots of potential! Flow player: 'Advanced' captions, scriptable, themable, free software. An audio SWF plugin is available - needs JS integration. http://flowplayer.org

At the top the content author creates a embeds a link using whatever syntax, for example, <a rel=&quot;embed&quot; href=&quot;http://youtube.com/watch...&quot;>..</a> The system (Moodle, Wordpress …) filter's this and calls the appropriate oEmbed service, either directly or, Via a Javascript library (jquery.oembed.js) The oEmbed provider (MALT Wiki, YouTube, Slideshare, Flickr…) returns the embed code. The embed code replaces the original link. Bingo. oEmbed specification, http://oembed.com oohEmbed proxy site, http://oohembed.com --
