Is there a ready-made video player with comments tied to the time?

Question

JavaScript

I would like to attach comments to the video player that are tied to the video timeline.
I'm interested in the interaction in both directions: so that the created comments have a label, and so that while watching the video, the comment feed gradually "scrolls" along the timeline.
Perhaps there are ready-made solutions?

Answer 1

If you need an analogue of nico nico douga, then there is no ready-made one.
