PiP End Time
video-mark-end
Sets the time in seconds at which the picture-in-picture overlay disappears from the main video.
video-mark-end accepts a float value in seconds from the start of the main video. After this time, the overlay is no longer visible. Use video-mark-end[N] for a specific overlay layer.
If video-mark-end is not set, the overlay remains visible until the end of the main video or until the overlay source is exhausted (see video-mark-eof).
