Do you have any other streams/manifests where you're seeing this issue?

Do you have any news/updates about that?

None at the moment. Can you reproduce the issue using those manifests and 
provide the receiver logs (including the expected stream duration for each)?

Do you only see this behavior with live streams? The Smooth Streaming 
specification (https://msdn.microsoft.com/en-us/library/ee673438(v=vs.90).aspx) 
says that duration should be set to 0 for live presentations whose approximate 
duration is not known in advance, which correlates to the streamDurations for 
the manifest files you provided.

Hi gents,

Main scenario here is:
in our app user able to switch from the middle of live event to the 
“recording in progress” of this event. For this case app show progress 
scrubber that indicates duration of this recording with ability to scrub 
through recorded content (scrubber.jpg)

But tricky part here is duration of recording constantly changes and we need to 
update progress on scrubber somehow.

To make this we decided to request manifest every 5 secs and count new duration 
based on chunks count until isLife flag is true. But I think this is non 
optimal solution, because manifest for items with duration > 5-10h will be to 
big.

Could you please suggest more efficient way to do this, if possible?
