Steps to reproduce

Closed captions / subtitles via the <track> element on a <video> element do not work cross domain. We are using the <track> element. The files on the other origin return the proper Access-Control headers.

Some background on how other browsers handle it:
All other browsers on all platforms seem to display captions with no problems. This includes Mac/Safari, iOS/MobileSafari, Mac/PC/Chrome/Firefox…

To reproduce:
Point your favorite browser at: https://util01.myodp.org/test/ie-cc-video-test.html
Watch captions work everywhere except Edge (and IE).

This is a serious accessibility issue, captioning (some) web video is required by the FCC and this should work with html5 coding.

      Changed Status to “Fixed”

    • This has been fixed in later builds of Win 10. Since you say that this was found in build 10586 - we will close it out as fixed. I am able to see captions just fine using 14393.105

      Thank you for the feedback.

      All the best,

    • Thanks for the info about later versions of Edge, I’ll have to upgrade it. Is there any chance that this will be fixed in IE 11? There’s such a large user base for IE even on Win10, and accessibility is key for so many.
