Playing Videos in HTML
Before HTML5, a video could only be played in a browser 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 page might flicker while the video loads.
The <source> element allows you to specify alternative video files which the browser may choose from. The browser will use the first recognized format.
The text between the <video> and </video> tags will only be displayed in browsers that do not support the <video> element.
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> The autoplay attribute does not work in mobile devices like iPad and iPhone.
