Is Oculus Quest 2 or 1 any good as a virtual camera in UE5 or UE 4.27

Hi Guys,
Just wanted to know if I can use Oculus quest 2 controller as position and rotation for my camera, in green screen video live tracking.
And what is the difference between vive tracker 3.0 and quest 2 controller.
And what capture card should I use to send my video from Blackmagic pocket 4k to unreal Engine in my Macbook pro.
Thanks.

I would also like to know
