# maySamplesWithEarlierDecodeTimeStampsHavePresentationTimeStamps(laterThan:)

Determines whether a sample earlier in decode order can have a presentation timestamp later than that of the specified sample cursor.

## Declaration

```swift
func maySamplesWithEarlierDecodeTimeStampsHavePresentationTimeStamps(laterThan cursor: AVSampleCursor) -> Bool
```

## Parameters

- `cursor`: An instance of AVSampleCursor with which to test the sample reordering boundary.

## Return Value

Return Value true if it’s possible for any sample earlier in decode order than the sample at the position of the receiver can have a presentation timestamp later than that of the specified sample cursor; otherwise, false.

## Discussion
