Comment (by TheRadziu):

 Through a proxy i've determined the difference between what works (other
 unnamed app and browsers) and doesn't (ffplay,ffmpeg,ffprobe) is constant
 value of "-720000". Meaning the ffplay tries to grab a segment that does
 not exist yet.
 I've been modifying the suggestedPresentationDelay  and the segment
 difference was still -720000. This leads me to conclusion the bug within
 ffmpeg/ffplay/ffprobe (all are affected) ignores MPD values instead of
 adjusting segments to it. My solution proposals are: find and fix the bug
 or allow user to specify the segment offset with additional ffplay
 argument.
