New Autoplay policies for Safari 11 and Chrome 64

New Autoplay policies for Safari 11 and Chrome 64

We are reaching out to you to inform you of how the new autoplay policies being implemented by Apple Safari and Google Chrome web browsers on PC/Mac will impact your Kaltura experience. This is most relevant to you if your organization currently creates players set to Autoplay or uses bumper videos, whether through the Kaltura video player, in MediaSpace, or in one of the Kaltura Application Framework (KAF) applications.

Changes Made by Browsers

Safari 11, released on September 19 for iOS11 and macOS, no longer supports autoplay for videos with sound. When set to autoplay, videos will now start muted, with sound being enabled only upon a specific user interaction with the player itself. When trying to set autoplay on videos with sound, autoplay will fail, and playback will require an explicit click on the ‘play’ button. 
Google has also announced changes to its autoplay policy, starting with Chrome 64, scheduled for release in early 2018.

To quote Google: “Under the new policy media content will be allowed to autoplay under the following conditions:

  • The content is muted or does not include any audio (video only)

  • The user tapped or clicked somewhere on the site during the browsing session

  • On mobile, if the site has been added to the Home Screen by the user

  • On desktop, if the user has frequently played media on the site, according to the Media Engagement Index

The Media Engagement Index (MEI) permit use cases are defined by Google. 

These changes help unify desktop and mobile web behavior, making web media development more predictable across different platforms and browsers.

How These Changes Will Affect Your Kaltura Experience

Just as with all other videos, Kaltura-based videos watched on one of the new browsers will be affected by these changes, and if set to autoplay, will start muted. We are updating the player as noted below to take this new behavior into account.

KMC Admin & Developers Guidelines:

  • Kaltura's newest player version, 2.62, released on Oct 22, will include the following changes to the autoplay flow:

    • By default, the player will fall back onto muted autoplay for browsers that block sound. You can also choose to fall back to an explicit 'Play' initiation on such browsers if you do not wish to play muted videos at all (add UIVar in the KMC Studio ‘autoPlayFallbackToMute’ set to False, or add it as a FlashVar to embedded players).

    • Playlist players will work as expected, start to autoplay in mute, and after a single user interaction all videos will continue to play with sound.

    • In autoplay mode, bumpers or ads will no longer require additional user interaction (once sound is turned on for an ad, the video will autoplay with sound as well).

  • For the above changes to apply, you will need to upgrade your video players now to the latest version (2.62). Please follow the Release Notes Page for updates on version releases and known issues

  • In the meantime, you can enable the ‘Muted’ option to ensure videos Autoplay on every browser (set ‘autoMute’ UIVar / FlashVar to True or enabling ‘Start Player Muted’ in the KMC Studio)
