# kCMSampleBufferDroppedFrameReasonInfo_CameraModeSwitch

A discontinuity was caused by a camera mode switch.

## Declaration

```swift
let kCMSampleBufferDroppedFrameReasonInfo_CameraModeSwitch: CFString
```

## Discussion

Discussion The module providing sample buffers has experienced a discontinuity due to a camera mode switch. Short discontinuities of this type can occur when the session is configured for still image capture on some devices.
