Comment (by alexlii):

 This is definitely a bug.

 '''it only happen with Safari on the site with SSL installed.'''

 here is the error message: Media error: Format(s) not supported or
 source(s) not foundDownload File:

 The author of mediaelement post a notification at
 https://github.com/mediaelement/mediaelement

 * IMPORTANT NOTE for Safari users (Jun 8, 2017)

 Since Sierra version, autoplay policies have changed. You may experience
 an error if you try to execute play programatically or via autoplay
 attribute with MediaElement, unless muted attribute is specified.

 For more information, read https://webkit.org/blog/7734/auto-play-policy-
 changes-for-macos/

 and here is Apple policy: https://webkit.org/blog/7734/auto-play-policy-
 changes-for-macos/

 Would you please let me know how to resolve?

 Alex
