For the community:

This problem appears when starting Unity using -force-metal parameter.

Don't -force-metal and your videofeed will work fine.

Hi What is this Force metal option? I am able to start the video when running directly. BUt i tried to import it in different project. I am using Macbook, the camera led starts but there is blank screen only

Sometimes  you get a message in the console saying something about "Metal: editor support disabled skipping device initialization"

And that error message dissapears when you start Unity with the -force-metal parameter; unfortunately (at least in my case) it messes with my camera.

Oh, yes. EasyAR does not support metal in current versions.
