# nextAvailableSampleBuffer()

Returns the next sample buffer if it is already available.

## Declaration

```swift
func nextAvailableSampleBuffer() -> AVPlayerItemSampleBufferOutput.SampleBufferInSequence?
```

## Discussion

Discussion If no sample buffers are ready, this method will return nil immediately. This method will race with nextSampleBuffer() for grabbing the generated sample buffer.
