Addressing quirksĪlthough web standards is used as much as possible, there are many nuances to tackle including caption support and rendering of HTML5 elements. The video progress indicator is implemented with a progress element as it “represents the completion progress of a task”. ![]() The volume setting is implemented with an input element with a type of range since it is “representing a number, but with the caveat that the exact value is not important”. Cases in point, the range input (slider) and the progress element. In addition to the Video element, other HTML5 features can go mainstream and work great in the video controls. The Mute and Captions controls are checkbox inputs because they each have two states, selected and not selected. The Restart, Rewind, Play, and Forward buttons use the button element. Careful attention was given to the semantics. The controlsĪs mentioned above, accessibility of video controls in browsers is still lacking, so they must be customized. This is the main use-case for the project. If rendered on a modern desktop browser with JavaScript, the experience is enhanced with custom controls, captions (if provided), and a slick design. This also occurs when JavaScript is unavailable on a desktop browser. The video element remains as-is if rendered a mobile or tablet device since native functionality is well-supported. So the code for the Accessible HTML5 Video Player starts with that the markup consists of only the Video element and a few divs for the controls, captions, and a container. Screen shot of the Accessible HTML5 Video Player Solid foundationīrowser support for HTML5 video is very good (only IE8 doesn’t support it). Support captions (uses WebVTT, the HTML5 standard).Make fully accessible especially to keyboard and screen reader users.Reduce code weight (the CSS is 5k and JS is about 18k, not minimized!).Take advantage of the latest web technology use HTML5 for the video, controls, and captions.The project takes advantage of HTML5 and avoids dependencies and plugins. Browsers’ native controls are still not accessible as a whole, nor is rendering captions.Īlthough browser support isn’t quite there yet, the new open-source Accessible HTML5 Video Player takes one big step closer to a fully standards-based and accessible video player. The player and its goalsĬustomizing an HTML video player is still required for a fully functional and accessible experience across browsers and platforms. It’s time to end this era and provide web-based video without plugins. But HTML5 video in IE has been supported since version 9. From applets to RealPlayer (who remembers that?) to QuickTime to Flash, and now the HTML Video element.įor the last few years, many HTML5 video implementations have included Flash fallbacks, especially for Microsoft’s Internet Explorer (IE). Video on the web has come a long way over the years.
