So far chromecast needs an internet connection to cast content to it. That means chromecast can't be used to cast downloaded Netflix videos without any internet. Internet is rather difficult on a ship on the sea or in a caravan in the outback. It seems to me a rather valid request since more and more apps allow downloading content and use it offline. At least as long as the device is set up, offline using should be possible.
Would it be possible to build a fixed ROM analoge to the Flashcast-Autoroot ROM (https://forum.xda-developers.com/and...oroot-t3270332
) which just allows using chromecast without an internet connection provided setup is already done? Does anybody have any infos disregarding?
