In https://github.com/whatwg/html/issues/192 MediaController was removed from HTML. I added wpt tests for the removal in https://github.com/w3c/web-platform-tests/pull/3686 From the issue, hober said: > I'm trying to dig up some usage data, but in the interim I can say that we are unlikely to drop support for MediaController absent a compelling alternative that addresses its use cases. roc made a proof-of-concept JS implementation at http://people.mozilla.org/~roc/videosync.html (unfortunately 404 now) showing that it's possible to get low enough lag in the sync for the stated use cases (but not frame-accurate syncing).

Which means that his proof-of-concept is insufficient to address the use cases for which MediaController is intended. It's highly unlikely WebKit will remove this feature until one that actually addresses these use cases can be specced and implemented.
@Jer Thanks for keeping MediaController! Leaving the developers with absolutely no choice seems hostile to me and I can't see how it could help the web platform. That being it said it seems our app will be work on Safari only.
We might still need to do something here: https://wpt.fyi/results/html/semantics/embedded-content/media-elements/historical.html?label=master&label=experimental&aligned=&q=safari%3Afail We are failing: > MediaController constructor should not be supported @Jer Noble - any plan to align with other browser now since it is only supported in Safari while other browsers have removed it?
