Therefore, the list of supported media publishers for “Autoplay” is the same our list of publishers for “Playback sync”. “Autoplay” requires playback sync so to pause/stop a playing video when another one on the page starts. Older browser versions will fall back to non-autoplaying media. Iframely will therefore try and mute media playback on mobile for all publishers that allow such control (see below).įor publishers that don’t provide such mute control, Iframely will simply fall back to non-autoplaying media variants.Īdditionally, WebKit has released the support of intersection observers in iOS 12.2. Most mobile platforms require a user gesture to autoplay a media with sound. Please consider &mute=1 and have all playback muted if most of your visitors are first-timers with no prior domain interactions.įor development and debugging purposes, you may also opt to change Autoplay-Policy via developer switches in chrome://flags/#autoplay-policy. If autoplay isn’t possible, most media publishers will simply catch a JavaScript error, and will fall back to their non-autoplaying variants by themselves.

In other words, whether a media will autoplay or not depends on your site’s user experience and engagement of an individual user. Autoplay with sound is allowed if user has interacted with the domain (click, tap, etc.) or if MEI threshold has been crossed. It is calculated individually for your web domain. If we cannot run visibility checks, Iframely will simply fall back to non-autoplaying media variants.Ĭhrome’s Autoplay Policy checks Media Engagement Index (MEI). The intention is to be gentle on end-user’s CPU and not to render your site sluggish with constant synchronous visibility checks. We deliberately do not fall back to the old school of visibility detections for the legacy browsers. Most modern browsers support the observers. Iframely will return a regular player instead so you can safely make API calls targeting only muted video.įirst and foremost, Autoplay feature relies on Intersection Observer to detect when media is visible to your user.

The combination of &autoplay=1 and &mute=1 is ambiguous for audio. You can omit the script, as with any other API call. HTML code in API response will point to Iframely iFrame and will also include the embed.js script. To mute the players on start for supported publishers on desktop (plus see Chrome browser below).
