Comment (by oromit):

 In order to play HLS the player has to download the last 3 segments of the
 list in advance. So you allways have at least a delay of segmentTime*3.
 There is nothing ffmpeg can do about that, that's just how HLS and similar
 systems work.

 Best you can do is reduce the length of your segments. But as each segment
 has to start with an I frame, there is a limit in how short you can make
 them.
