The JavaScript library mwEmbed is downloaded directly from the project web-

site (http://html5.kaltura.org/js) and then sorts out how the video can be played.

In any case, a small control bar appears at the bottom edge of the video. Fig-

ure 4.7 shows the reaction of Internet Explorer 8, which does not yet know the

HTML5 video element: To play the Ogg video, it loads the Java applet Cortado.

If you are not happy with Java applets as replacements for native video in the

browser, you can use the html5media library instead.
