Playback not starting after switch to mediaplayer.js library 0.6.0 #250

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Put sample stream to http server and try to play it using mediaplayer.js ver. 
0.6.0 and 0.5.0. With 0.6.0 playback cancelled with error after first segment 
received.

Expected: No serious side effects between releases, especially when in release 
notes there is nothing related to HLS.

P.S. In attach simple 3 sec video sample. By analyzing log with mediaplaye.js 
ver 0.6.0 this sample not playable. Fetching of segment cancelled after first 
segment received (and assume parsed) by Chromecast. But if I simply replace 
mediaplayer.js un receiver application to 0.5.0 - works fine. Same thing 
happens with longer (~ 1 hour) video streams.

Nginx 1.4.5 used as static http server for testing purpose.

And please there is any chance to get more detail information thru Chrome 
Remote Debugger or any callback with details when this kind of problem happens? 
For example we wanna know why Chromecast rejecting our stream instead of spend 
a lot of time on it. It's possible to get any useful detail information thru 
onError callback?

We were not able to reproduce this; it worked fine when we ran that against 0.6 
library; here is the log:

Strange... (((( But anyway thanks. There is any ability to get detailed logs 
thru Chrome Remote Debugger ?

Have you already turned on logging on your receiver 
(cast.receiver.logger.setLevelValue(cast.receiver.LoggerLevel.DEBUG)?

Thanks my previous log level was ERROR, I change it to DEBUG. But still logs 
not informative enough. I cannot understand why Chromecast just cancelled 
playback after first segment was downloaded.
