This article is Ready to Use.
Allows developer to specify multiple alternative media resources for media elements, such as
<audio>. It does not represent anything on its own, and is used with
src attribute to specify the URL.
src= URL potentially surrounded by spaces
The address of the media source.
type= MIME type
The type of the media source (used for helping the UA determine, before fetching this media source, if it can play it).
A string that identifies a valid MIME media type, as defined in [RFC2046].
media= media-query list
The intended media type of the media source (used for helping the UA determine, before fetching this media source, if it is useful to the user).
A valid media query list, as defined in [MediaQueries].
<video controls="controls"> <source src="http://media.w3.org/2010/05/sintel/trailer.mp4" type='video/mp4; codecs="avc1, mp4a"/> <source src="http://media.w3.org/2010/05/sintel/trailer.ogv" type='video/ogg; codecs="theora, vorbis"/> <p>Your user agent does not support the HTML5 Video element.</p> </video>
Note If you change the media file using the src property on an audio or video object, you need to call the load method before calling the play method. If you change the src and call the play() method without loading first, it will continue to play the file specified by the source element.
