This post describes a change to how videos with sound work in Cascade story maps.<\/em><\/p>\n

Web browsers\u00a0have\u00a0been\u00a0implementing\u00a0stricter policies on autoplaying videos with sound. In\u00a0April 2018, Google’s Chrome browser updated its autoplay policy to\u00a0block videos with sound from autoplaying<\/em>\u00a0(for additional technical info see\u00a0this article on\u00a0the\u00a0Google Developers site<\/a>). Apple’s Safari browser had already\u00a0implemented\u00a0a similar policy, and other browsers are likely to implement similar policies in the near future.<\/p>\n

According to Google:<\/p>\n"},{"acf_fc_layout":"blockquote","content":"

...web browsers are moving towards stricter autoplay policies in order to improve the user experience, minimize incentives to install ad blockers, and reduce data consumption on expensive and\/or constrained networks. These changes are intended to give greater control of playback to users and to benefit publishers with legitimate use cases.<\/p>\n"},{"acf_fc_layout":"content","content":"

Developers must\u00a0adhere to these policies when building apps and websites since browsers are the tools\u00a0people use to\u00a0view web content.<\/p>\n

How did browsers’ policy changes affect Cascade stories?<\/h3>\n

Previously, Cascade stories were able to autoplay videos with no restrictions; but recently some browsers began blocking videos with sound from autoplaying.\u00a0As a result, Cascade stories with unmuted immersive background videos<\/em> were no longer\u00a0working as expected. Readers using the latest version of Chrome or Safari may have seen a blank space where a video should have been playing.<\/p>\n

What has changed in Cascade?<\/h3>\n

Since several popular browsers now block autoplaying videos with sound, the following changes were made in the April 2018 update to Story Map Cascade to address the changes caused by these new policies:<\/p>\n
