Videos no longer streaming with mediaelement.js in Chrome

I could replicate this problem with Chromium 51.However it appears this problem does not occur anymore with Chrome 53.

Unfortunately I have been unable to find an easily readable confirmation on the Internet, that this was a confirmed bug for Chromium/Chrome that got fixed, but just indications that several people reported issues with Chrome/Chromium versions. e.g. here Videos no longer streaming with mediaelement.js in Chromewhere Google Chrome Developer cwilso points to this internal chromium mailing list, but whose contents are rather cryptic without further research. It appears to be related to a switch called ENABLE_BROWSER_CDMS and the EME implementation for DRM support, that was not working as it was supposed to.https://groups.google.com/a/chromium.org/forum/#!topic/chromium-reviews/Qi4dLcKjcCM

That is because since Chrome 50 a play() call on a <video> or an <audio> element returns a Promise. If playback succeeds, the Promise is fulfilled, and if playback fails, the Promise is rejected along with an error message explaining the failure.

You can find some examples and more information here: https://developers.google.com/web/updates/2016/03/play-returns-promise?hl=en

It also can be a CORS issue. Set media.crossOrigin = 'anonymous'; And make sure that the server response has the header Access-Control-Allow-Origin: *. Or instead of the asterisk wildcard, specify the domain of the website that is allowed to access the video from the server.
