# kVTDecompressionPropertyKey_DecoderProducesRAWOutput

A value that indicates whether the decoder can produce RAW output requiring a RAW processing session for post-decode processing.

## Declaration

```swift
let kVTDecompressionPropertyKey_DecoderProducesRAWOutput: CFString
```

## Discussion

Discussion If this property isn’t implemented, it’s assumed that the decoder does not produce RAW output. If the decoder reports that it produces RAW output, the VTDecompressionSession internally invokes a VTRAWProcessingSession by default to produce processed output. If the client sets kVTDecompressionPropertyKey_RequestRAWOutput, the VTDecompressionSession performs no processing and returns the decoder’s native RAW output, and ignores any requested image buffer attributes.
