# AVSampleBufferGeneratorBatch

An object that generates sample buffers in a batch.

```
class AVSampleBufferGeneratorBatch
```

## Overview

The benefit of batching is it aggregates adjacent I/O requests and overlaps them when possible for all sample buffers within the batch.

## Topics

### Preparing a batch

[`makeDataReady(completionHandler:)`](/documentation/AVFoundation/AVSampleBufferGeneratorBatch/makeDataReady(completionHandler:))

Loads sample data asynchronously for all sample buffers within a batch.

### Canceling a batch

[`cancel()`](/documentation/AVFoundation/AVSampleBufferGeneratorBatch/cancel())

Cancels any I/O for this batch.
