# AVQueuedSampleBufferRendering

Methods you can implement to enqueue sample buffers for presentation.

## Declaration

```swift
protocol AVQueuedSampleBufferRendering : NSObjectProtocol
```

## Overview

Overview AVSampleBufferDisplayLayer and AVSampleBufferAudioRenderer conform to this protocol. When used in conjunction with an AVSampleBufferRenderSynchronizer, an object conforming to AVQueuedSampleBufferRendering can only be attached to a single synchronizer.
