# hasSufficientMediaDataForReliablePlaybackStart

A Boolean value that indicates whether the enqueued media data meets the renderer’s preroll level.

```
var hasSufficientMediaDataForReliablePlaybackStart: Bool { get }
```

## Discussion

Apple discourages the use of this symbol in iOS 17, tvOS 17, and macOS 14 and later. Use [`hasSufficientMediaDataForReliablePlaybackStart`](/documentation/AVFoundation/AVQueuedSampleBufferRendering/hasSufficientMediaDataForReliablePlaybackStart) on the [`sampleBufferRenderer`](/documentation/AVFoundation/AVSampleBufferDisplayLayer/sampleBufferRenderer) instead.
