Autoplay and Browser Behaviour


The Behaviour tab in the Playout settings allows you to set the autoplay configurations. It varies how different browsers deal with autoplay videos with sound. When a browser does not permit a video to autoplay with sound, the player will automatically mute the video and autoplay on mute.

Please see the box below to see how various browsers deal with autoplay.

1.0 | Google Chrome

Muted autoplay is always permitted. Autoplay with sound is only permitted if the use has interacted with the domain (such as clicking or pressing keys) or if the MEI (Media Engagement Index) limit has been reached. This limit is reached when:
– The user has played a video with sound on the respective website within the same browser session
– The user has added the site to the home screen of their mobile phone
– The user has installed the PWA (Progressive Web Apps) web application on their desktop

2.0 | Safari

Muted autoplay is always permitted. Autoplay with sound is only permitted if the user has interacted with the domain (such as clicking or pressing buttons).

3.0 | Firefox

Muted autoplay is always permitted. Firefox has the default to block autoplay videos with sound. Autoplay with sound is only allowed if the user has interacted with the domain (such as clicking or pressing buttons).

4.0 | Microsoft Internet Explorer 11

Microsoft IE11 permits autoplay as a default. Since there are no built-in settings for this, it’s difficult for users to adjust (limit or block) these settings themselves. This is where Microsoft IE11 differs from its successor Microsoft Edge.

5.0 | Microsoft Edge (previously Internet Explorer)

Microsoft Edge allows users to personalise their browser preferences on websites that use autoplay videos with sound. Users can choose whether to allow, limit, or block autoplay. In addition to this general setting, users can choose to customise settings for a specific website. Settings per website take precedence over the general settings. Unlike many other browsers, Microsoft Edge’s default setting is to allow autoplay when a user does not set any preferences for it.

6.0 | Mobile Devices

For mobile devices, such as Apple iPhones, Apple iPads, most Android and Microsoft devices, autoplay is rarely or never permitted. Therefore, assume that autoplay will not be possible on these mobile devices.
