This is sensible, given that mobile bandwidth is often limited and expensive. Many, if not all, mobile browsers will ignore the autoplay attribute, so the video will always wait for the user to press the play button before starting. Here’s how you’d use this attribute: Warning: Mobile Browsers Ignore autoplay But this doesn’t mean that the autoplay attribute should never be used.įor example, if the page in question contains nothing but a video-that is, the user clicked on a link to a page for the sole purpose of viewing a specific video-it may be acceptable for it to play automatically, depending on the video’s size, surrounding content, viewing platform, and audience. Usability best practice dictates that sounds and movement on web pages should only be triggered when requested by the user. Normally, this is a bad practice most of us know too well how jarring it can be if a website starts playing video or audio as soon as it loads-especially if our speakers are turned up. The Boolean autoplay attribute does exactly what its name implies: it tells the web page to play the video immediately as soon as possible. We’d love to omit reference to this particular attribute, since using it will be undesirable for the most part however, there are cases where it can be appropriate. Figure 5.1 and Figure 5.2 show how these controls differ in appearance from browser to browser.įigure 5.4. Its inclusion in the markup tells the browser to make the controls visible and accessible to the user.Įach browser is responsible for the look of the built-in video controls. HTML5’s video element includes a controls attribute that does just that: Ĭontrols is a Boolean attribute, so no value is required. No embedded video would be complete without giving the user the ability to play, pause, stop, seek through the video, or adjust the volume. Naturally, these values can be overridden via scripting or CSS. The width and height attributes accept integers only, and their values are always in pixels. This stops the video from stretching unnecessarily and looking distorted. For example, if the video in the previous example was actually 375×240 and the markup was as shown, the video would be centered vertically inside the 280-pixel space specified in the HTML. Similar to the img element, the video element can also include width and height attributes:Įven though the dimensions can be set in the markup, they’ll have no effect on the aspect ratio of the video.

In a perfect world, it would work everywhere-the same way the img element works everywhere-but that’s a little way off just yet.

It is, however, the minimum code required to have HTML5 video working to some extent. The simplest way to include HTML5 video in a web page is as follows: Īs you’ve probably figured out from the preceding sections, this will only work in a limited number of browsers. The MarkupĪfter that necessary business surrounding containers, codecs, and licensing issues, it’s time to examine the markup of the video element and its associated attributes.

Now Chrome’s security feature will be fulfilled and the video should play as normal and if the user wants to hear the video, they’ll have to unmute it. To mute the video add a “muted” attribute like so:

So the solution is pretty simple, you have to mute the video and then, only then, will Chrome play it normally when the page loads. The sound would start to play and Chrome doesn’t want that. The issue with this is Chrome would not play the video because it hasn’t been muted. Using the HTML5 video tag, if I were to add a video to a page that has the controls visible, autoplays, and loops the code would look like this: It will block it because it doesn’t want the user hearing an unwanted video. For example, they added a feature that won’t play a video on a website if the sound is enabled.
