How to turn a CVPixelBuffer into a UIImage?

Question

I\'m having some problems getting a UIIMage from a CVPixelBuffer. This is what I am trying:

CVPixelBufferRef pixelBuffer = CMSampleBufferGetImageBuffer(imag

Another way to get an UIImage. Performs ~10 times faster, at least in my case:

int w = CVPixelBufferGetWidth(pixelBuffer);
int h = CVPixelBufferGetHeight(pixelBuffer);
int r = CVPixelBufferGetBytesPerRow(pixelBuffer);
int bytesPerPixel = r/w;

unsigned char *buffer = CVPixelBufferGetBaseAddress(pixelBuffer);

UIGraphicsBeginImageContext(CGSizeMake(w, h));

CGContextRef c = UIGraphicsGetCurrentContext();

unsigned char* data = CGBitmapContextGetData(c);
if (data != NULL) {
   int maxY = h;
   for(int y = 0; y
