vImageConvert_422CbYpCrYp8ToARGB8888 conversion missing red and black/alpha - Cocoa - objective-c

Question

I am trying to convert an CVPixelBuffer format from YUV('2vuy') to ARGB using Accelerate framework with the below code.
CVPixelBufferLockBaseAddress(pixelBuffer, 0);
void* baseAddress = CVPixelBufferGetBaseAddress(pixelBuffer);
size_t srcBufferWidth = CVPixelBufferGetWidth(pixelBuffer);
size_t srcBufferHeight = CVPixelBufferGetHeight(pixelBuffer);
size_t srcBufferBytesPerRow = CVPixelBufferGetBytesPerRow(pixelBuffer);
vImage_Error err = kvImageNoError;
static vImage_YpCbCrToARGB outInfo;
static bool infoGenerated = false;
if (!infoGenerated) {
vImage_YpCbCrPixelRange pixelRange;
pixelRange.Yp_bias = 16;
pixelRange.CbCr_bias = 128;
pixelRange.YpRangeMax = 235;
pixelRange.CbCrRangeMax = 240;
pixelRange.YpMax = 255;
pixelRange.YpMin = 0;
pixelRange.CbCrMax = 255;
pixelRange.CbCrMin = 1;
const vImage_YpCbCrToARGBMatrix *matrixYpCbCrToARGB = kvImage_YpCbCrToARGBMatrix_ITU_R_709_2;
err = vImageConvert_YpCbCrToARGB_GenerateConversion(matrixYpCbCrToARGB, &pixelRange, &outInfo, kvImage422CbYpCrYp8, kvImageARGB8888, kvImageNoFlags);
if (err ==kvImageNoError) {
infoGenerated = true;
}
}
if (infoGenerated) {
const uint8_t permuteMap[4] = {0, 1, 2, 3};
vImage_Buffer srcBuffer = { (void *)baseAddress, srcBufferHeight, srcBufferWidth, srcBufferBytesPerRow};
void *destData = malloc(srcBufferWidth * srcBufferHeight * 4);
vImage_Buffer destBuffer = {
.data = destData,
.width = srcBufferWidth,
.height = srcBufferHeight,
.rowBytes = srcBufferWidth * 4
};
err = vImageConvert_422CbYpCrYp8ToARGB8888(&srcBuffer, &destBuffer, &outInfo, permuteMap, 0, kvImageNoFlags);
if (err!=kvImageNoError) {
NSLog(#"vImage_Error converting vImageConvert_422CbYpCrYp8ToARGB8888 errorcode:%ld",err);
}
CVPixelBufferUnlockBaseAddress(pixelBuffer, 0);
}
The conversion is successful but the resulting destination buffer has a blue shade. I want it in the original colour. What Am I missing or doing wrong here?
