Rendering

Answer 1

Try including these two lines

webView.allowsInlineMediaPlayback = YES;
webView.mediaPlaybackRequiresUserAction = NO;

These lines solved my issue which is occurring in iOS 12.2

Answer 2

Is it embedded using UIWebView or WKWebView or similar?

Try setting mediaPlaybackRequiresUserAction to YES for the webview. I'm seeing the same issue (UIWebView and WKWebView both) in iOS 12.2. Works fine in iOS 12.1 and earlier.

When debugging, you see this error in safari console:

Unhandled Promise Rejection: NotAllowedError: The request is not allowed by the user agent or the platform in the current context, possibly because the user denied permission
