Chromecast Stops Casting Channel #48

Open jcderr opened 9 years ago

jcderr commented 9 years ago

After returning from a trip this week, my Chromecast loses its connection to Greenscreen after ~5-10 minutes. Looking at the Chromecast debugger by going to :9222 eventually provides an error saying "Detached from target". The new Chromecasts were released while I was away and it appears (though I'm not 100% sure) that this device got a firmware update as well.

The Greenscreen console output does not yield any interesting information at all.

I started having similar issues within the timeframe you describe. I have been unable to come to a resolution for the problem.

After a bunch of troubleshooting, I think the issue is actually with the latest Chromecast firmware, but I'm not entirely sure. If I use my chromecast with other apps (say, Netflix), after a few hours I'll get the brain freeze message and the stick will reboot.

WIth greenscreen set to cast just one URL to the stick, it'll happen after an hour or few, and the more URLs I have the channel rotate, the faster the brain freeze arrives. With 3-4 URLs, it happens in 10-15 minutes.

For testing I have bypassed green screen entirely. For now I am casting to each of my 6 displays using multiple chrome users on a single machine. I am letting the displays sit for now to see if they will continue to fail when green screen has no role in the process. I hope this will show if the chromecasts are themselves the issue as I have been unable to locate a cause.

I am having the same issue. If I only have 1 url on a channel it is fine but any more and the switching between urls on channels gets slower and slower until I get a black screen then the chromecast powers back on to the chromecast home screen. This is a massive problem. One possibility we are considering is that the "channel" is too heavy for the chromecast and it's getting a ram overload. How to solve this, we have no idea. Again this has only started happening since the chromecasts got a new update.

I posted to try and see if the issue is related to the chromecasts and not greenscreen as based on my troubleshooting I do not believe it to be a greenscreen issue. https://code.google.com/p/google-cast-sdk/issues/detail?id=682

It appears someone is having similar brain freeze issues when casting a video for extended periods of time.

The summary of my issues I posted and troubleshooting I found relevant: I have 6 chromecasts that all experience the same issues. After casting for a few hours they all go to the brain freeze screen and restart. This issue appears to occur both when app and tab casting. I primarily use greenscreen (https://github.com/groupon/greenscreen) to cast to multiple chromecasts at a time loading an HTML page similar to the one pasted below. This has only started to occur recently (since approximately the launch of the new chromecast) and was working without incident prior' casting non stop for days on end. When app casting I am using a custom receiver to accomplish my goal. To lessen the likelihood of an app related issue I also tried casting directly from multiple tabs. I created multiple users in Chrome and then cast individually from each one without the use of my app and the issues reoccur there as well. Other users under similar circumstances are reporting the same problems. To troubleshoot the possibility it was script related I used the greenscreen app to load different webpages in succession cycling every 15 seconds and the issues occurred under these circumstances as well.

Per google recommendation please do the following "Please send feedback report from the Chromecast (how to here: https://support.google.com/chromecast/answer/6189374?hl=en) and in the description write "for Issue 681".

I can only assume the more widespread our bug reports are the more likely the issue will be addressed.

This issue looks like a showstopper for anyone considering Greenscreen. The Google tickets (https://code.google.com/p/google-cast-sdk/issues/detail?id=682, https://code.google.com/p/google-cast-sdk/issues/detail?id=681) show no indication of a resolution. Has a newer firmware since this issue was created resolved the issue?

This is still an issue. Has been no improvement and have not heard anything back from chromecast support. As a work around to limit the frequency of the disconnects we have put "light"(light on memory being used) urls on the channels. This not a good solution but the only one we have right now.
