android - Chromecast Custom Receiver to play premium content -

I am working on the ChromeCast Custom Receiver app and am using the iFrame API to load YT videos. The point is that the receiver app which puts "YouTube premium content" when the "Uploader has not made this video available in your country" message.

I think we must execute some authentication process in the receiver application YT Premium Content

1. How can I add authentication to the receiver app to play YT Premium content?

2. Do we have any

thanks in advance

This is probably not possible because YouTube uses a cookie-based login system that can not be passed to Chromecast Say, an Oeth2 Token (for APIs) can be passed. Playing premium content is prohibited without having to log in to YouTube on YouTube.
