Chapter 5. Video on the Web
Diving In
Anyone who has visited YouTube.com in the past four years knows that you can embed video in a web page. But prior to HTML5, there was no standards-based way to do this. Virtually all the video youâve ever watched âon the Webâ has been funneled through a third-party plug-inâmaybe QuickTime, maybe RealPlayer, maybe Flash. (YouTube uses Flash.) These plug-ins integrate with your browser well enough that you may not even be aware that youâre using themâuntil you try to watch a video on a platform that doesnât support that plug-in, that is.
HTML5 defines a standard way to embed video in a
web page, using a <video>
element. Support for the <video>
element is still evolving, which is a polite way of saying it doesnât work
yet (at least, it doesnât work everywhere). But donât despair! There are
alternatives and fallbacks and options galore. Table 5-1 shows which browsers
support the <video> element at
the time of writing.

Support for the <video>
element itself is really only a small part of the story. Before we can
talk about HTML5 video, you first need to understand a
little about video itself. (If you know about video already, you can skip
ahead to What Works on the Web.)
