# AVAssetWriterInput.PixelBufferReceiver

Provides an interface for writing pixel buffers to an input.

```
class PixelBufferReceiver
```

## Topics

### Appending pixel buffers

[`func append(CVReadOnlyPixelBuffer, with: CMTime) async throws`](/documentation/AVFoundation/AVAssetWriterInput/PixelBufferReceiver/append(_:with:))

Suspends until the input is ready for more media data, then appends the pixel buffer.

[`func appendImmediately(CVReadOnlyPixelBuffer, with: CMTime) throws -> Bool`](/documentation/AVFoundation/AVAssetWriterInput/PixelBufferReceiver/appendImmediately(_:with:))

Appends the pixel buffer synchronously if the input is ready for more media data.

[`func finish()`](/documentation/AVFoundation/AVAssetWriterInput/PixelBufferReceiver/finish())

Indicates to the AVAssetWriter that no more buffers will be appended to this receiver.

### Accessing the pixel buffer pool

[`var pixelBufferPool: CVMutablePixelBuffer.Pool?`](/documentation/AVFoundation/AVAssetWriterInput/PixelBufferReceiver/pixelBufferPool)

A pixel buffer pool that will vend and efficiently recycle pixel buffer objects that can be appended to the receiver.

[`var sourcePixelBufferAttributes: CVPixelBufferCreationAttributes?`](/documentation/AVFoundation/AVAssetWriterInput/PixelBufferReceiver/sourcePixelBufferAttributes)

The pixel buffer attributes of pixel buffers that will be vended by the receiver’s pixel buffer pool.
