The source for the audio or video is given in the src attribute. You can use the controls atttribute to specify how the plug-in is display. Set the autostart to false if you do not want the audio or video to play automatically when the page loads. You could set the loop atttribute to true if you wanted the audio or video to repeat as long as the page is displayed.
Just like images, the alt attribute provides a short description of the audio or vido for text-only browsers and screen readers. The align, height, and width attributes also work just like they do with the embedded image element.
