Is it possible to use Actions on Google to stream a video to Chromecast?

Question

The promotion videos of Google Assistant show that it can stream a video on the family's chromecast. However, https://developers.google.com/actions/ doesn't talk about that feature.

Is this feature already implemented?

Answer 1

Although Google Home and Google Assistant can control media devices and streaming - this is not something that works through the Actions on Google API yet. It was mentioned at I/O that there would be an API to send things to a Chromecast display, although the details aren't available.
