Warning: Can only update a mounted or mounting component

[fernando-di]

I am trying to use example that you added on this repo. The trouble is that when I open the screen video player works video plays but it shows this error in yellow:
Warning: Can only update a mounted or mounting component this usually means you called setState, replaceState or forceUpdate on an unmounted component. This is a no-op. Pleas check the code for video player component.

Is there any way to solve this issue?

This is harmless warning, but yes, I would like to get rid of it. I'm not sure where in the code this is caused though. Any ideas?
