#Google chrome autoplay video blocker online code#
Head over to the wiki for documentation, support info, and more: įrom Version 1.2 we rewrited all the code and solved most of the major problems, Google has partially rolled back Chrome’s blocking of autoplaying video with sound after it was found to break a large collection of web apps and games. This allows for restrictions on media control and simulation of expected behavior to ensure that all pages behave normally. In addition to removing the HTML autoplay attribute from media elements, Disable HTML5 Autoplay also hooks into the media's JavaScript API. THIS EXTENSION IS CURRENTLY UNMAINTAINED Please see GitHub for the latest news: ĭisable HTML5 Autoplay disables HTML5 audio and video autoplaying. Make sure you do not fall into this trap.Disables autoplay of all HTML5 audio and video Disables autoplay of all HTML5 audio and video Inevitably, they run into situations where autoplay fails and the user has no way of clicking to make the video play. We have seen sites try to get fancy and be too minimalist by hiding controls. Have I mentioned showing controls for your player? Always make sure controls for your player are accessible.You may notice that twitter and a lot of sites start videos in the muted state. You will want to show some kind of “muted” icon in the UI that the user can click to unmute (again, the default video controls attribute works great for that). Consider starting with the video muted, this gives you a much lower chance of your ay() call rejecting.If you are using your own custom controls and your javascript calls ay() again as the result of an event that bubbled up from a user click, then it will work. If the promise returned from ay() rejects, then show a play button in the UI so that the user can click to play (the default video controls attribute will work just fine).If the promise resolves, then autoplay worked, if the promise rejects then autoplay was blocked. Use ay() in javascript world, which returns a promise.I’m not suggesting that you avoid autoplaying videos, but I am suggesting that you always avoid the autoplay attribute. As a developer, this is incredibly frustrating and another reason to always avoid the autoplay attribute. But then when new users come to your site, it is likely to fail (because their MEI score is low). When you are testing autoplay on your own site it will probably work for you (because you visit your site often and play content, your MEI score is high). One thing to keep in mind (for Chrome at least) is that due to Chrome’s Media Engagement Index. Autoplay will probably work for you, but it will break for your usersĮven if you try to follow the rules above, autoplay is still a finicky beast. This basically means that you can never rely on autoplay actually working. These conditions only make autoplay more likely, but remember that aside from these conditions, the user can override the browser’s default setting on a per-domain basis. (Safari) Device is not in power-saving mode.(Chrome - mobile) The user has added the site to their home screen.Chrome keeps track of how often a user consumes media on a site and if a user has played a lot of media on this site then Chrome will probably allow autoplay. (Chrome - desktop) The user’s Media Engagement Index threshold has been crossed.The user has interacted with the page with a click or a tap.Your video is muted with the muted attribute.There are however some conditions that make it more likely for autoplay to work: The default behavior is block most autoplay attempts. It’s a huge black box and browsers will not tell you what their exact rules are. Each browser has slightly different rules around how it makes this decision. In summary: all these browsers will aggressively block videos from autoplaying on webpages. Safari announced some policy changes in June 2017 and Chrome followed suit shortly after and Firefox after that. Over the last few years, all major browser vendors have taken steps to aggressively block autoplaying videos on webpages. Browsers will block your autoplay attempts Let’s talk about why that’s probably not what you’re looking for and what the better option is. This sounds exactly like what you’re looking for, right? Well, not exactly. If you’re trying to autoplay videos on the web, you might be tempted to reach for the HTML5 autoplay attribute.
