问题
I have an unpublished custom receiver app, and I am unable to cast to it from my web player sender app in chrome. I do get the receiver "available" message upon initialization of cast api, but when I click on the cast button in player and select the chromecast device from drop down menu in extension, the TV screen goes black and few seconds later I get onError method called with following error:
{code: "channel_error", description: "Error: Timeout", details: null}
The casting works fine when using default media receiver. Also, I do not see any network traffic coming from chromecast device in my server console log, which means that chromecast is not fetching the receiver application.
I made sure of the following:
- The Chromecast dongle is registered as Cast Receiver device in Cast Developer console.
- My macbook has NodeJS server running to serve the receiver application and the "Receiver Application URL" in cast developer console is correctly pointing to server running on my macbook.
- The chromecast and my macbook both are on same network, with valid 192.168.x.x IP addresses.
I found another thread discussing this error Chromecast sample sender application CastHelloText-chrome ends with error when trying to get session, but the suggestions provided there dont seem to apply to my situation.
回答1:
I was able to resolve this particular error by restarting the chromecast device. I tried it on two separate occasions and both times the issue went away once the device was restarted. I can't explain how it worked, but it did the job. If someone can explain what is the cause of this particular error and why restarting fixes it, I will accept that answer.
