Live dash with segment template don't work. #787

Open GoogleCodeExporter opened 8 years ago

MPL MPL 1.0.0.29
Play any live dash with segment template and you will see it will not working 
when you set initialTime to Infinity.
It's working if you set the initialTime before the actual live position but if 
you set initialTime to Infinity = (MPL should start from the live position). 
MPL will use mediaPresentationDuration -30s as the live position.
We think MPL should calculate the live position like this.

Segment number to start with is ((current_time - (availabilityStartTime + 
period.start)) / fragment_duration) + startNumber
so how long time this period has been available divided by fragment_duration is 
how many fragments has been published after representations startNumber
that is live position.

We need a private way to share streams with you, because our unencrypted 
streams may not be spread on the internet. (it's sharp content).
The issue occurs both on Chromecast Generation 1 or 2 because the logic is not 
implemented in MPL. You don't need a Chromecast to verify this, you can run MPL 
in Chrome Desktop to see that MPL don't working with live DASH streams, because 
MPL doesn't calculate the Live Point correct.
