On iOS 9, s will only begin playing as a result of a user gesture.
Since most of these GIFs started out their lives as video clips, were converted into animated GIFs, and were again converted back to video clips, you might say that the circle is complete.īut while this move does spare websites’ bandwidth costs as well as saving users’ batteries, it comes at a usability cost. It’s so expensive that many of the largest GIF providers have been moving away from GIFs and toward the element. We’ve found that GIFs can be up to twelve times as expensive in bandwidth and twice as expensive in energy use. But the GIF format turns out to be a very expensive way to encode animated images when compared to a modern video codec like H.264. It turns out that people these days really like GIFs. For Safari in iOS 10, we are further relaxing this user gesture requirement for silent elements. But with the goal of returning more control over media playback to web developers, we relaxed this restriction in iOS 8: Safari began honoring the preload="metadata" attribute, allowing and elements to load enough media data to determine that media’s size, duration, and available tracks. When Safari first supported in iPhoneOS 3, media data loaded only when the user interacted with the page. Equally, if you have any questions don’t hesitate to drop me a message on social media.Since before your sun burned hot in space and before your race was born, Safari on iOS has required a user gesture to play media in a or element. If you’ve enjoyed this post I’d really appreciate it if you shared it around online. There you have it, an inclusive, progressively enhanced replacement for animated GIFs using HTML5 video.
If you have an iOS device (iPhone/iPad), you can turn on reduced motion by following these steps:
Autoplay video html mobile mac#
If you have a mac you can turn on reduced motion by following these steps: If this is the first time you’ve heard of the prefers-reduced-motion query Val Head sums it up perfectly, in her post: The reduced motion query at a glance.Įssentially, we can tone down or remove motion that may be harmful to those with vestibular disorders or motion-sensitivities.Ĭurrently, this feature is only supported in Safari, but will hopefully be adopted by other browsers sometime soon. That being said, I will expand on the prefersReducedMotion() method. I’ve added comments to the JavaScript so it should be pretty clear what’s going on. Instead of jumping straight in, let’s progressively enhance the markup we’ve created.įirst things first, let’s hide the buttons we just added if they aren’t needed:
You might be thinking it’d be much easier to just change the icon between states. Why do we have a separate button to play the video and a separate button to pause the video. Ok, let’s address the elephant in the room. With that covered, let’s have a look at the markup: This can cause someones vestibular system to struggle to make sense of what is happening, resulting in loss of balance, vertigo, migraines, nausea, and hearing loss. There are many reasons someone might want to pause a video ranging from saving battery life to suffering from vestibular disorders. To make our autoplaying videos more inclusive, we’re going to add play/pause buttons, so users can pause the video if they don’t want it to play.
