Live stream using SegmentURL is not working
See original GitHub issueI’m trying to use the SegmentURL but it seems that shaka-player is not able to play it. It’s showing the message:
streaming_engine.js:1368 (audio:3) cannot find segment: currentPeriod.startTime=0 lookupTime=839769.003000021
The funny thing is, when I change to my SegmentTimeline representation (to the same data) it works.

What did you do? Just tried to play it.
What did you expect to happen? Play it.
What actually happened? It didn’t start to play and it shows the following message streaming_engine.js:1368 (audio:3) cannot find segment: currentPeriod.startTime=0 lookupTime=839769.003000021

Hi Leandro,
We are going to need a manifest URI (and license server URI, if applicable) that we can use to reproduce the error. The contents of the manifest are not sufficient to reproduce a bug. If you can’t post a URI publicly, you can send one to shaka-player-issues@google.com. Anything you send there will be kept confidential.
Thanks!
@joeyparrish we should keep this closed, the TV we were testing is playing regular HLS but maybe in the future we can come back to this, thank you very much!
