Live stream stops after a few seconds #632

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
This live stream plays for only a few seconds on the Chromecast and then stops. 
I tried 4 different Chromecast Android apps and they all had the exact same 
behavior. The FireTV plays it just fine and VLC also. This isn't the first time 
I've seen live streams be somewhat unstable under the Chromecast but it is 
probably the most reproducible I've seen.

Which apps did you use? What version of Android and Chromecast are you using?

GoogleCodeExporter commented 8 years ago 
I tried it on a Nexus 5 with Android 5.1.1. 

I tried it on Vega Cast, Cast2TV-Lite, and a couple others.

Sorry I forgot. 38401 is what it says today, don't know if it updated since 
yesterday.

Can you confirm that the error occurs on version 38401?

Tried it on the Cast2TV app and it played for maybe 10 seconds and then 
stopped.

It seems like there's segment(s) in the stream that the Chromecast is having 
trouble processing. We'll look into it.

Do you know what software was used to create the live stream?

Original comment by jonathan...@google.com on 14 Aug 2015 at 11:26

GoogleCodeExporter commented 8 years ago 
No sorry I don't. A user sent it to me and I don't even know where it came 
from.

Any luck figuring out this issue? I've seen it with other streams, or at least 
the console error looks the same.

It seems that there are segment(s) with timestamps that are not monotonically 
increasing. Due to the nature of HTML5 Media Source Extensions, this is a 
requirement for Chromecast. Please see 
http://www.w3.org/TR/2015/CR-media-source-20150331/ (search for "monotonically 
increasing").

Thank you for the information, so I'm guessing other players like vlc and 
firetv are just ignoring that?

I can't say for sure since I don't know how they are implemented, but I would 
assume so.

Closing this ticket as Invalid since the issue was due to the stream not 
following MSE specifications.
