# producesRAWOutput

Indicates whether the decoder produces RAW output which requires the use of a RAW processor.

```
optional var producesRAWOutput: Bool { get }
```

## Discussion

The extension should implement this property returning <doc://com.apple.documentation/documentation/ObjectiveC/YES> if the decoder produces RAW output which requires the use of an [`MERAWProcessor`](/documentation/MediaExtension/MERAWProcessor) for post-decode processing to produce renderable output.

This optional property is queried on the extension when a Video Toolbox client queries the <doc://com.apple.documentation/documentation/VideoToolbox/kVTDecompressionPropertyKey_DecoderProducesRAWOutput> property on the hosting <doc://com.apple.documentation/documentation/VideoToolbox/VTDecompressionSession>.
