Chapter 1. HTML5 Audio and Video Elements: By-Default
The media elements, as the HTML5 audio and video
elements are generically termed, are a way of embedding playable media files
directly into a web page without having to use Flash or a plug-in. The
elements can be styled with CSS, integrated with SVG and Canvas, and
controlled with JavaScript.
Browsers and other user agents that implement the HTML5 media elements also provide default controls and behavior for each. In this chapter, I cover how to add HTML5 video and audio elements to your web page, and explore some of the implementation differences among the browsers. I also cover the more widely supported media file codecs and containers, and browser support for each.
