Video on the Web
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.
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:
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:
|Internet Explorer 9+||YES||NO||NO|
- MP4 = MPEG 4 files with H264 video codec and AAC audio codec
- WebM = WebM files with VP8 video codec and Vorbis audio codec
- Ogg = Ogg files with Theora video codec and Vorbis audio codec
MIME Types for Video Formats
HTML5 <video> - DOM Methods and Properties
HTML5 has DOM methods, properties, and events for the <video> and <audio> elements.
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.
