HTML5 web video

 

Until now, there is still no standard for displaying videos on webpages.

Today, most videos are displayed through plug-ins (such as flash. However, not all browsers have the same plug-ins.

HTML5 specifies a standard method to include videos through video elements.

 

 

Video Format
Currently, the video element supports two video formats:

Internet Explorer Firefox 3.5 opera 10.5 chrome 3.0 safari 3.0
Ogg x
MPEG 4 x

Ogg = Ogg file with thedora video encoding and Vorbis Audio Encoding

MPEG4 = MPEG 4 files with H.264 video encoding and AAC audio encoding

How to work
To display videos in HTML5, all you need are:

<Video src = "movie.ogg" controls = "controls">
</Video>

 

The control attribute allows you to add playback, pause, and volume controls.

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

The content inserted between <video> and </video> is displayed by browsers that do not support video elements:

 

 

Instance

 

<Video src = "movie.ogg" width = "320" Height = "240" controls = "controls">
Your browser does not support the video tag.
</Video>

 

 

The above example uses an Ogg file, which is applicable to Firefox, opera, and chrome browsers.

Make sure that the video file type is MPEG4 for safari.

The video element allows multiple source elements. The source element can be used to link different video files. The browser uses the first recognizable format:

Instance <Video width = "320" Height = "240" controls = "controls">
<Source src = "movie.ogg" type = "Video/Ogg">
<Source src = "movie.mp4" type = "Video/MP4">
Your browser does not support the video tag.
</Video>

 

 

Internet Explorer
Internet Explorer 8 does not support video elements. In ie 9, video elements of MPEG4 are supported.
