As you can see, time difference between 12:30:00 and 12:57:28 are 27:32 sec. Nevertheless, AVItemPlayer.duration and Quicktime player are showing 28:13 seconds. Last chunk don't provides date-time because is truncated before 10 seconds which is target duration.
In the real life, when I play the stream without interruptions, duration is 27:32. But if I seek in the timeline duration it increase to 28:13.
I'm showing some markers in the timeline and this cause to place them in incorrect position. Do you know why player could be calculating incorrect duration and how to fix it?
