Public Types
using	AVHWFramesContextDeleter = void (*)(struct AVHWFramesContext *ctx)

Static Public Member Functions
static HwFrameContextData &	ensure (AVFrame &hwFrame)
	gets or creates an instance of the class, associated with the frames context of the specified frame. Note, AVFrame holds shared ownership of the frames context, so consider this when designing HwFrameContextData's lifetime.
