Beginning HTML5 Media, Second Edition is a comprehensive introduction to HTML5 video and audio. The HTML5 video standard enables browsers to support audio and video elements natively. This makes it very easy for web developers to publish audio and video, integrating both within the general presentation of web pages. For example, media elements can be styled using CSS (style sheets), viewed on a mobile device, and manipulated in a Canvas or an audio filter graph. The book offers techniques for providing accessibility to media elements, enabling consistent handling of alternative representations of media resources. The update includes all of the changes and revisions since the first HTML5 draft.
