mediaplayer: limit scheduling video frames into the future

This addresses when video timestamps jumps before an audio timestamp,
but still works on slideshow video clips (<=1fps).

This, however, will not skip time-changes on video-only live video
streams, as we cannot distinguish live slideshow video clips from
non-slideshow ones.
