# kCMSampleBufferConsumerNotification_BufferConsumed

Optionally posted when a sample buffer is consumed.

## Declaration

```swift
let kCMSampleBufferConsumerNotification_BufferConsumed: CFString
```

## Discussion

Discussion If a sample buffer has a value for the kCMSampleBufferAttachmentKey_PostNotificationWhenConsumed attachment, an object that consumes the sample buffer should post this notification with itself as the notifying object and the attachment value as the userInfo dictionary.
