How to add subtitles (.SRT files) to videos?

Question

I need to add subtitles from .srt files over to a video yt array, for traslate the language http://jsfiddle.net/vLd34wnx/

The srt files link to each video should be loaded every time the player starts displaying them as it happens with images.

example:

const videos = [
[ 'RGpr3Y6Q-1M', 'picture.png' ],
