I have a complicated react app dealing with video streams, but this question can boil down to something a lot simpler. Basically, I need to buffer a video “in the background”, using a hidden div (don’t ask me why), and meanwhile display the current video. Then it cycles through n number of videos every few seconds, buffering the next video while the current video plays.

I’m facing a problem and it seems I can’t find a working solution since a few years.

The following algorithm is for a short time test, how can I find the answer very quickly
