We have an option to create a subtitle track in the old Kaltura player. Our new player doesn't have this yet.
The option is basically a link to the File name, but then in the TimedText namespace. This is considered to be the 'root' for all language variants of the the subtitles: https://commons.wikimedia.org/w/index.php?title=TimedText%3AFolgers.ogv
The challenge is to determine WHERE to add this option. Hiding it in the menu never was very discoverable, but worse, in the new player the entire menu is hidden if there are no tracks.
An option might be to add them via some sort of hover menu, and have a drop down there. Perhaps together with an embed and a share dialog ?
