Mirroring GVRMainActivity with Chromecast

[retterdesdialogs]

Our app is a Kiosk app and we would like to stream, mirroring what the user sees to a tv. I know it is possible through the oculus app, but our app is a b2b app and there is no access to the "Cast Google Chrome Button".

We achieved to make the app to act as sender app, so we can connect to the chrome cast. But then we stuck.

How to use the Cast RemoteDisplay api in a gvrf environment to stream the GVRMainActivity via chrome cast?

Any thoughts?

Barring from implementing the streaming yourself by capturing screenshots and send over wireless connections, I wonder if you can get the app's View

and then pass that view to CastRemoteDisplay()

In either case, the streaming process likely will make your app slow

@retterdesdialogs Maybe you could consider switching to Daydream. Might be possible to use the built-in support Daydream provides.

@retterdesdialogs https://github.com/googlecast/CastRemoteDisplay-android is a good example for that. The Oculus backend adapter will have to be modified. The eye buffer texture id can be passed to the cast presentation so it can render it to a full-screen quad.
