After running cronjobs for a while the server loses connection with the Chromecast and starts erroring out. The web interface can't connect to it at all. Restarting the server fixes the issue. Funnily enough restarting the Chromecast also works.

On the network level Keep-Alive's, SYN's, ACK's and PSH's seem to be flowing normally but when it comes to sending the job to the Chromecast only RST's are sent. In my particular case 8 of them for one cronjob.
Also the amount of packets seem to go way up. After a few hours of running the average amount of TCP packets sent between the server and the Chromecast is around 100 per second. Normally it seems to be around 3 per second.

I compiled the .war-file myself from the latest source code. Getting a new release out could be beneficial since I'm guessing it uses a vulnerable version of Log4j.

Thanks for the project though! It's been very interesting to research.

First, this tool has been awesome! I've used it for several years now, displaying a Grafana dashboard in kiosk mode through a gen1 CC.

I'm updating to a new Grafana server and rebuilding my dashboard. The new server is on Grafana v6.6.2 and the old one is v5.4.2. Trying to cast to any CC in the house on the new version now presents only a white screen. If I cast from a Chrome browser it works fine. If I cast the old dashboard it works fine.

Something in Grafana v6.6.2 isn't working right with the kiosk. I'm not sure if it's a page formatting problem that Chrome browser now understands.

Any ideas?

It should be possible to group casts so you could send groupwise data

Feature request to add RPiCast capability. The RPi W is much less expensive than a Chromecast, but isn't able to act as a ChromeCast receiver. It would be nice to extend the functionality of this to support the RPiCast receiver since they don't have something like this on the RPiCast side.

When I create a cronjob, the resulting URL's always seem to have a "+" at the end. Because of this they won't load/resolve correctly on the chromecast and I end up with a white screen.

If I use the "start cast" interface, the same URL will load properly.

Thank you for this project. Very simple/clean and gets the job done.

I'm chromecasting a Grafana dashboard to a 1080P TV through a Gen1 Chromecast. The page is not displaying like a 1920x1080 pixel size. It appears to be closer to 720P. I'm not sure if this is a capability reporting problem on the pull from Grafana or on the push to the Chromecast. The TV believes it's operating at 1080P.

the the config file currently located in WEB-INF/config will be replaced every time the presenter.war is updated.

I am trying to start a cast of a dashboard and I type everything in and I am getting an error and a returned http 415, here is my raw request.

As for my environment, I am using docker with fabric8/tomcat-9 and other things work well.

It would be great if in the overview under the current app of a chromecast, you'd be able to see exactly what's being cast in the form of a title or URL of a web page.
When everything is labeled as "chromecast-kiosk-web" it doesn't really tell you that much.

The problem is, I'm not sure if it's even possible to pass such information along to or from a chromecast.

Just noticed this is possibly a duplicate of #6

Any ideas why when I cast to any chromecast I only get a blank white screen. I have tried multiple websites with the same results. Simply casting from the chrome tab works, but not from the Kiosk System.

Thanks!

It seems like the presenter.war is 8 months old, and there have been features added since.
I tried to build a new one myself, but didn't succeed.

I'm mainly looking to use the cronjob feature to schedule casting of pages.
