In the current implementation, both kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange and kCVPixelFormatType_420YpCbCr8BiPlanarFullRange correspond to kRec601_SkYUVColorSpace (aka kRec601_Limited_SkYUVColorSpace).

We need to treat them differently, let kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange correspond to kRec601_Limited_SkYUVColorSpace, and kCVPixelFormatType_420YpCbCr8BiPlanarFullRange correspond to kJPEG_Full_SkYUVColorSpace
