Traits

PictureReclaimableSurface

Represents a state where one can reclaim the underlying Surface for this Picture. This is true when either no decoding has been initiated or, alternatively, when the decoding operation has completed for the underlying vaSurface

PictureState

A Picture will only have valid YUV data after a sequence of operations are performed in a particular order. This order correspond to the following VA-API calls: vaBeginPicture, vaRenderPicture, vaEndPicture and vaSyncSurface. This trait enforces this ordering by implementing the Typestate pattern to constrain what operations are available in what particular states.
