How do i use my iphone as both the camera video input and live virtual camera tracker?

Hello world.

I have been researching up and down trying to figure out how i can use ONLY my iphone as both the camera video input and live camera tracker for virtual production without an additional camera such as a dslr.

Please and thank you.

I’m not sure if this will help you or not the video but worth to check it might help

Thank you @199102 looks promising as i noticed if it works have this run the virtual camera while the video input on plane is the phone camera.
