如何将YUV数据转换为CVPixelBufferRef？

Question

我下面有Yuv数据：

@property(nonatomic, readonly) int chromaWidth;
@property(nonatomic, readonly) int chromaHeight;
@property(nonatomic, readonly) const uint8_t *dataY;
@property(nonatomic, readonly) const uint8_t *dataU;
@property(nonatomic, readonly) const uint8_t *dataV;
@property(nonatomic, readonly) int strideY;
@property(nonatomic, readonly) int strideU;
@property(nonatomic, readonly) int strideV;

现在如何将其转换为CVPixelBufferRef？
