# currentChunkInfo

A value that provides information about the chunk of samples to which the current sample belongs.

## Declaration

```swift
var currentChunkInfo: AVSampleCursorChunkInfo { get }
```

## Discussion

Discussion If the media format that defines the sequence of samples doesn’t indicate chunking of samples, the cursor considers each sample to belong to a chunk of one sample only.
