Yelp Audio & Video
Yelp supports adding audio and video objects to documents. It uses the HTML5 <audio> and <video> elements.
To add audio or video to a Mallard document, use the media element ( or ), and set the type attribute to "audio" or "video". See also for information on adding subtitles to audio and video objects in Mallard documents.
Yelp will use the non-TTML contents of the media element as the fallback content in HTML. To provide an image to use for the HTML video poster attribute, provide a child image media element with the style attribute set to "poster".

To add audio to a DocBook document, use the audioobject element ( or ) in a mediaobject or inlinemediaobject element. To add video, use the videoobject element ( or ).
Yelp will use a textobject element ( or ) from the containing mediaobject or inlinemediaobject for the fallback content in HTML. If inline, Yelp uses a textobject that contains a phrase element. Otherwise, it uses a textobject that contains normal block content.
