poster is a URL to an image that will be displayed before a user presses Play (video only).src specifies a single media file for playback (for multiple sources with different codecs, please see the discussion below).The audio and video elements introduce several new attributes that determine how the browser will present the media content to the end user. HTML5 Media Attributes and Child Source Tags For a more XHTML-like syntax you could write controls='controls', but the browser always considers controls to be false if it’s not present and true if it is present or assigned a value. Controls is a Boolean attribute, which means it doesn’t need to have a value assigned to it. This tells the browser to display its own built-in playback control bar, which usually includes a play/pause toggle, a progress indicator and volume controls. You can also use the style attribute to specify px or % width and height values (I’ll use both in the examples that follow). But, just as with img tags, it’s always best to specify the height and width attributes so that the page doesn’t need to reflow. When the browser has downloaded enough of a video to determine its native height and width, it resizes the video accordingly. It’s much simpler-just plain HTML that needs very little explanation. In the days of using Flash or Silverlight for video playback, the simplest possible markup to display a video (video.mp4 in this case) would have looked something like this: Ĭompare those nested object, param and embed tags with this HTML5 video tag used to play the same h.264-encoded video:

Some Android devices include Flash, but Adobe has recently discontinued its mobile Flash efforts, which means that HTML5 will be the only way to play media on mobile devices in the future.

In addition, mobile devices running Windows Phone 7.5, Apple iOS and Android (as well as the Metro-style browser in Windows 8) support media playback only through HTML5 video and audio. Moreover, media that uses HTML5 video and audio performs better than media played through plug-ins such as Flash or Silverlight, resulting in longer battery life and smoother playback. HTML5 media has built-in support for captions and subtitles using the new track element, and proposals for additional features-such as direct byte access for video manipulation-are already being considered. If you can create buttons in HTML and control them with JavaScript, you already know all you need to develop HTML5 media.

The advantage of using HTML5 for media is that you can leverage your HTML, CSS and JavaScript skills rather than learning Flash or Silverlight. In this article, I’ll explore the benefits of using HTML5 for media playback, show some sample code, address some major issues that developers face and present solutions to those problems. Even retrofitting existing Flash and Silverlight video content for HTML5 playback has become fairly simple. Browsers and JavaScript libraries have matured to the point where you can-and should-use HTML5 media as the default for any projects that will display audio and video content.

The tags were great for companies writing experimental code or doing cross-browser media development, but the HTML5 media API was too unreliable for general use. When the HTML5 audio and video tags were first introduced, codec and browser incompatibilities made them difficult to use and unrealistic to deploy on large-scale Web sites. The first recognized format is used by the browser.Volume 27 Number 02 Building HTML5 Applications - Practical Cross-Browser HTML5 Audio and Video The “source” element is used to specify the audio files which the browser may use. The below Examples explain the audio Tag:Įxample 1 (Adding audio to Webpage): The controls attribute is used to add audio controls such as play, pause, and volume.

The support for each format by different browsers is given below : Supported Formats: Three formats mp3, ogg, wav are supported by HTML5.

muted : Designates that the audio file should be muted.

src : Designates the URL of the audio file.

Loop : Designates that the audio file should continuously repeat.

Autoplay : Designates that the audio file will play immediately after it loads controls.

Controls : Designates what controls to display with the audio player.
