# kVTDecompressionPropertyKey_PixelBufferPoolIsShared

A Boolean value indicating whether a common pixel buffer pool is shared between the video decoder and the session client.

## Declaration

```swift
let kVTDecompressionPropertyKey_PixelBufferPoolIsShared: CFString
```

## Discussion

Discussion This value is false if separate pools are used because the pixel buffer attributes specified by the video decoder and the client are incompatible.
