When using the TrueDepth front-facing camera on iPhone X, setting the capture device’s activeFormat to a binned video format (see AVCaptureDeviceFormat isVideoBinned) for capture and enabling delivery of camera calibration data causes the resulting AVCameraCalibrationData to contain invalid information for the intrinsicMatrix property. (34200225)
Workaround: Select an alternate capture format whose isVideoBinned property is false.
Note: Configuring a capture session using a session preset never selects binned formats.
