根据official documentation，看来kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange到kCVPixelFormatType_420YpCbCr8BiPlanarFullRange是kCVPixelFormatType_420YpCbCr8Planar到kCVPixelFormatType_420YpCbCr8PlanarFullRange。
kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange
kCVPixelFormatType_420YpCbCr8BiPlanarFullRange
kCVPixelFormatType_420YpCbCr8Planar
kCVPixelFormatType_420YpCbCr8PlanarFullRange
但是文档未指定更高版本的i420像素格式的范围。有什么区别？
