# incorrectlyConfigured

The system is incorrectly configured for the requested operation.

```
static var incorrectlyConfigured: AVError.Code { get }
```

## Discussion

The system raises this error when you attempt to perform an incorrectly configured operation. For example, HTTP Live Streaming presents only a single video and audio track at a time. If you’re using [`AVAssetWriter`](/documentation/AVFoundation/AVAssetWriter) to generate a fragmented MPEG-4 asset for streaming, adding more that one video and audio [`AVAssetWriterInput`](/documentation/AVFoundation/AVAssetWriterInput) to the asset writer generates an error when you start writing.
