Hi,
To be honest I have no idea if this is relevant, but if I cast something then I see a screenshot of DashCast now I see this in there issues list, would this be an option for the 10 minute problem with the Google hubs?
I was running into the same issue. In the Google Docs it says you can use disableIdleTimeout. So I am trying this:
window.castReceiverManager.start({statusText: "Application is starting", disableIdleTimeout: true});
Replace line 163 in receiver.html with the above. I am not 100% sure that it works, but according to the docs it should.
stestagg/dashcast#12
If not please forget and close the issue, but hey always nice to test I think?
