We are creating MP4 deliverables with soft embedded 'Closed captioning'. In addition, we have the WebVTT file used to create the 'closed captioning'.

We would like the OOB Videojs to allow customers to switch on/off closed captioning. At the moment this capability is not present in the OOB viewer. This support is available for VideoJS - https://github.com/videojs/video.js/blob/master/docs/guides/text-tracks.md. This functionality needs to be added as an enhancement to the VideoJS player and any new OOB Video players

This is also accessibility issue that we need to address
