Question about ultra low latency

Created by: yogevNisim

Hey, in my project we have a live stream produced using dashcast (after some modifications) for ultra low latency.

We see in the network that the player always request one segment before the live edge. Why is that happening? if the segment is ready in the server side i would like it to be requested and received by the client. how do you suggest to modify the code in order to fix this. meanwhile i manage to fix it by adding "+1" to the number returned by timelineconverter.js - calcPresentationTimeFromWallTime()
