Playing Videos in HTML

Before HTML5, there was no standard for showing videos on a web page.

Before HTML5, videos could only be played with a plug-in (like flash).

The HTML5 <video> element specifies a standard way to embed a video in a web page.


Browser Support

The numbers in the table specify the first browser version that fully supports the <video> element.

Element
<video> 4.0 9.0 3.5 4.0 10.5

The HTML <video> Element

To show a video in HTML, use the <video> element:

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>

How it Works

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

It is a good idea to always include width and height attributes.

If height and width are not set, the browser does not know the size of the video. The effect will be that the page will change (or flicker) while the video loads.

Text between the <video> and </video> tags will only display in browsers that do not support the <video> element.

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


HTML <video> Autoplay

To start a video automatically use the autoplay attribute:

Example

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

Note The autoplay attribute does not work in Safari and Opera, or in mobile devices like iPad and iPhone.

HTML Video - Methods, Properties, and Events

HTML5 defines DOM methods, properties, and events for the <video> element.

This allows you to load, play, and pause videos, as well as setting duration and volume.

There are also DOM events that can notify you when a video begins to play, is paused, etc.

Example: Using JavaScript
