问题
Does the content stream from WiFi directly to Chromecast, or from WiFi to Android (or any other device) to Chromecast?
I know that the other devices can be used to control the Chromecast, but I just want to know whether say you can stream directly from your mobile due say to battery life.

The mobile device is only used for the initial content discovery phase where the user selects a video stream to watch. Once playback is initiated, the Chromecast device connects to the internet over WiFi and downloads the stream data without requiring the mobile device to be turned on.
More details available on the official Chromecast developer site.
