Live streams repeat after x seconds.

[Jacktail]

In Chrome I am finding that live streams work, but after 30 seconds they just loop those 30 seconds.
The streams work fine in IE.

It is just Chrome where it loops.

My test area is here, http://198.50.191.222/DASH/dashjs/

Streams work fine with bitdash.

Sorry I can't be more technical, I am not a web dev.

@Jacktail, it seems that the issue is in the mpd - availabilityStartTime attribute is changing after each manifest update while the spec requires it to be the same all the time:
"When the MPD is updated, the value of MPD@availabilityStartTime shall be the same in the original and the updated MPD" (p. 8.4.2)

This sounds the same as #600 and is probably a wowza configuration issue, which i think you said elsewhere you were using. See the advice in comments regarding mpegdashStrictSpecComplianceForAST setting.

@KozhinM Thanks! That single comment saved me from a lot more headaches. Especially because it directly contradicts with Wowza's documentation

Added mpegdashStrictSpecComplianceForAST property for enabling strict spec compliance of the segment availability parameters provided in the live MPEG-DASH MPDs. Should not be enabled when using dash.js-based players such as the Wowza Streaming Engine Manager test DASH player

But this is no surprise since Wowza's own reference MPEG-Dash player doesn't even work.

I can confirm that this fix the issue on latest Chrome from Wowza 4.2 to Dash.js 1.4. This seems to be only required for live video streaming as vod streams are ok.
Thanks for the tip - saved me some serious hours of work :)
