A simple app that grabs raw camera data, converts to textures and renders on screen using
The app uses two reusable components with (hopefully!) simple and straightforward interfaces:
MetalCameraSession helps you grab raw camera data as pixel buffers with either of two pixel formats and convert it to a Metal texture (or textures). You can choose either of two pixel formats:
