# CVMutablePixelBuffer.Pool.Configuration

Configuration passed to pixel buffer pool on creation.

```
struct Configuration
```

## Topics

### Initializers

[`init(ageOutDuration: TimeInterval, minimumBufferCount: Int)`](/documentation/CoreVideo/CVMutablePixelBuffer/Pool/Configuration/init(ageOutDuration:minimumBufferCount:))

Create new configuration instance

### Instance Properties

[`var ageOutDuration: TimeInterval`](/documentation/CoreVideo/CVMutablePixelBuffer/Pool/Configuration/ageOutDuration)

Backing memory of released buffers is kept around for this duration before being freed (default is 1 second). If
set to 0, the backing memory of released buffers is freed immediately.

[`var minimumBufferCount: Int`](/documentation/CoreVideo/CVMutablePixelBuffer/Pool/Configuration/minimumBufferCount)

The pool keeps at least this many buffers alive. These buffers do not participate in the age-out mechanism.
