Delayed Seek in HTML5 provider

[coladeu]

Can you do a caption delay control feature? To control the subtitle delay if is out of sync? Or can you tell me with what line of the code from jwplayer.js do i have to play in order to get an effect on caption delay?

@coladeu There is no feature for captions delay. When the HTML5 provider is active we're using the browser's native playback capabilities, and this includes native captioning. We can't modify the times of native captions because they exist outside of the player. When rendering non-natively, I suppose you could modify the start time immediately after parsing here (https://github.com/jwplayer/jwplayer/blob/master/src/js/controller/tracks-loader.js#L68) or when parsing, here (https://github.com/jwplayer/jwplayer/blob/master/src/js/parsers/captions/vttparser.js#L234). I'm not sure how well or if this will work at all, though.
