# kVTDecompressionPropertyKey_SupportedPixelFormatsOrderedByPerformance

An array indicating speed tradeoffs between pixel formats (optional).

## Declaration

```swift
let kVTDecompressionPropertyKey_SupportedPixelFormatsOrderedByPerformance: CFString
```

## Discussion

Discussion This is an optional property for video decoders to implement. This property value is an array containing CFNumber objects holding CMPixelFormatType values,	ordered by speed from fastest to slowest.
