Use Device Camera instead of Webcam on Play

Question

I've downloaded and used Vuforia with success and when I play the project, It uses my webcam on my laptop. But how can I use my connected iPhone's camera instead when I play the project in Unity?

Answer 1

Simple answer: You can't.

Vuforia accesses the camera hardware directly with C++ and not with Unity's WebCamTexture API. This would have worked with the new Unity Remote 5 if they used WebCamTexture in their API to get camera frames, but they didn't because WebCamTexture is extremely slow for image processing.
