We tried to verify the chromecast functionality on the Android TV development board with gtvs enabled.
At present, we can search our chromecast device on YouTube app(Phone) and Chrome browser (PC), but can't connect or cast.
When searching with Chrome browser, the browser displays: "Applicable for specific video sites", and cannot be selected.
There have some errors related to “MAC Address”, “bootid”, “ClientAuthCreds”, “Widevine UUID unsupported”, etc.
But I'm not sure what the problem is.
So I hope some one can help analyze the causes of the problem and give solutions
Here are error logs:
