Description

With 2,315 errors on group 2 wikis, 4,830 on group 1 wikis this is one of our most prominent JavaScript errors

It has no stack trace or file url but mostly impacts webm and ogv files on iOS devices (Chrome and Safari) on mobile domains, so I assume this relates to support for those file formats on mobile devices.

Without a stacktrace, it's gonna be pretty hard to figure out where this problem is.

Kaltura player is not longer maintained. The issue doesn't seem to occur in VideoJS player, judging by the error logs after T248418:
