This happens on files with many overlapping subtitle events before the first
packet of another stream. The combined durations of the subtitle events can
exceed the max_analyze_duration before reading any of the other streams (even
if they also start at the same timestamp).
I also considered simply skipping this check for subtitle streams; sound better?
