Until now, there has not been a standard for showing a video/movie on a web page.
Today, most videos
are shown through a plug-in (like flash). However, different browsers may have
different plug-ins.
HTML5 defines a new element which specifies a standard way to embed a video/movie
on a web page:
the <video>
element.
How It Works
To show a video in HTML5, this is all you need:
Example
<video width="320" height="240" controls="controls">
<source src="movie.mp4" type="video/mp4" />
<source src="movie.ogg"...
