PiP Loop

Controls whether the picture-in-picture overlay video loops when it reaches its end.

video-mark-loop accepts a boolean value. When set to true, the overlay video loops continuously for the duration of its display window (defined by video-mark-start and video-mark-end). When set to false, the overlay plays once and then follows the behavior set by video-mark-eof.

Use video-mark-loop[N] for a specific overlay layer.
