Allow us to set the buffer on a per stream basis, say to 6.33s. The video player would slightly speed up or slow down to compensate. Since the buffer fluctuates constantly, maybe over a 5 second average.

This would be useful mainly for syncing multiple streams and keeping them in sync.

I know this is already possible and very straight forward since the player already speeds up high delay streams. It simply needs to read the current buffer and adjust accordingly.

This is such an easy thing to implement and would reduce the frustration of out of sync streams completely.
