DASH Live stream stalls

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use Basic Chrome sender application 
https://github.com/googlecast/CastHelloVideo-chrome which I assume uses 
Receiver chrome.cast.media.DEFAULT_MEDIA_RECEIVER_APP_ID
2. Load Custom DASH Live with updating segment timeline media 
http://vm2.dashif.org/livesim-dev/segtimeline_1/testpic_2s/Manifest.mpd

What is the expected output? What do you see instead?
I expect the video to play smoothly.
Instead the playback stalls for 2-4 seconds and then resumes for 2-4 seconds 
repeatedly

What version of the product are you using? On what operating system?
FW Version 1.17.48342

Please provide any additional information below.
From the Network log on my receiver it seems the Chromecast does not request 
all the segment needed and misses many segments

We analyzed the timeline of the segments requested in a live clear DASH 
content. 
Each segment has two values:
• The time the segment has been requested by Chromecast (relative to an 
arbitrary time when Wireshark capturing has started).
• The segment timestamp (part of the segment file name).
We got 9 segments before the Chromecast stopped requesting segments.
Attached a linear regression analysis of the data extracted from Google’s 
Chromecast app, playing clear live DASH content 
(http://192.118.34.209/data/dash_clear/master.mpd)

The x-axis: The actual point in time when the segment has been requested.
The y-axis: The segment timestamp value.
We’d expect the slope to be 1, i.e. the progress in the requested segments 
timeline should be equal to the actual timeline.
The actual slope is 1.945, which means the Chromecast requests segments too 
fast, probably until it requests segments which doesn’t exist yet.
