HTML5 video autoplay on mobile revisited

There have been some changes since the last time I tested autoplay videos. Animated GIFs have become popular, because they work on mobile. A problem is that animated GIFs can become very large. A video is typically a lot smaller. That is why Apple and Google decided to allow autoplay in their mobile browsers. But only if videos are muted. On iOS you also have to set the playsinline attribute, because by default videos will play fullscreen.

To get autoplay use the following setup:

<video controls autoplay loop muted playsinline>
  <source src="video.mp4" type="video/mp4">
  <source src="video.webm" type="video/webm">

My tests show that the latest mobile browsers now support autoplay with the exception of MS Edge.

[update] Opera Mini on iOS 10 supports autoplay, but plays the video fullscreen. Other versions do not autoplay as one would expect from a proxy browser.

[update] Firefox on iOS does not support autoplay. This is very different from Firefox on Android that supports autoplay even with sound.

[update] On Samsung devices, the default browser is Samsung Internet. It is uses the same basis as Chrome, but it's not updated as frequently.

Of course, you do not have to use autoplaying videos everywhere.
