Will running an
AVCaptureDevice
at a 1920x1080 AVCaptureDeviceFormat
consume more battery than a format at say 640x480?If on say an iPhone Plus, where there exists a resolution exactly equal to the screen resolution, you're at least saving a resizing operation on the GPU (I'm using Metal).
Is upsizing from 640x480 to 1920x1080 a more expensive operation than say, downsizing from 3840x2160 to 1920x1080?
Running an app with a camera background, that also uses the camera to capture media... so trying to make some intelligent battery life decisions on choose formats.
