endMicros

When the cue stops being visible. The cue shows from startMicros up to, but not including, this time.

The built-in sources give a text cue with no end one before it reaches the engine. The SubRip and WebVTT parsers close it at the next cue's start, or 3 seconds later when no cue follows. The FFmpeg backend holds a text cue from a packet with no duration for 10 seconds, and an ASS event for 5 seconds. A cue from a stream that gives no end, as Blu-ray subtitles and teletext pages do, arrives as OPEN_END, and the engine closes it at the start of the next cue of its track. A custom source sets its own end.
