HTML5 Video

Video on the Web


Before HTML5, there was no standard for showing videos/movies on web pages.

Before HTML5, videos could only be played with a plug-in (like flash). However, different browsers supported different plug-ins.

HTML5 defines a new element which specifies a standard way to embed a video or movie on a web page: the <video> element.




Browser Support


Internet Explorer Firefox Opera Google Chrome Safari

Internet Explorer 9+, Firefox, Opera, Chrome, and Safari support the <video> element.

Note: Internet Explorer 8 and earlier versions, do not support the <video> element.




HTML5 Video - How It Works


To show a video in HTML5, this is all you need:

Example


<video width="320" height="240" controls>
  <source src="movie.mp4" type="video/mp4">
  <source src="movie.ogg" type="video/ogg">
Your browser does not support the video tag.
</video>

The control attribute adds video controls, like play, pause, and volume.

It is also a good idea to always include width and height attributes. If height and width are set, the space required for the video is reserved when the page is loaded. However, without these attributes, the browser does not know the size of the video, and cannot reserve the appropriate space to it. The effect will be that the page layout will change during loading (while the video loads).

You should also insert text content between the <video> and </video> tags for browsers that do not support the <video> element.

The <video> element allows multiple <source> elements. <source> elements can link to different video files. The browser will use the first recognized format.




Video Formats and Browser Support


Currently, there are 3 supported video formats for the <video> element: MP4, WebM, and Ogg:

HTML5 <video> - DOM Methods and Properties


HTML5 has DOM methods, properties, and events for the <video> and <audio> elements.

These methods, properties, and events allow you to manipulate <video> and <audio> elements using JavaScript.

There are methods for playing, pausing, and loading, for example and there are properties (like duration and volume). There are also DOM events that can notify you when the <video> element begins to play, is paused, is ended, etc.

The example below illustrate, in a simple way, how to address a <video> element, read and set properties, and call methods.

Example 1


Create simple play/pause + resize controls for a video:

Play/Pause Big Small Normal

The example above calls two methods: play() and pause(). It also uses two properties: paused and width.
