No, your chromecast downloads and runs a webapp, and you give instructions about what to play from your computer/phone. That's hlw you can play a webradio and turn off your phone for example

That's an implementation detail and doesn't say anything about casting in general.

The discussion is not about casting in general, it's about chromecast

I started it and I asked about casting in general. Chromecast is the only type of casting VLC supports; because of that I think its not living up to it's name.
