The Chromecast isn't much of a streamer. It is functionally more of a wireless display adapter and as such, cannot function without some other streaming device feeding it.For file streaming, I will fall back to the chromecast.
That is all the Chromecast is capable of. I believe that as a technology device it was way oversold as to what it would bring to the experience. Google promised OTT, DLNA and more but that is entirely dependent on a fully capable and independent streaming device to feed it.generally with the chromecast I am mirroring a display window from a tablet or laptop.
