Get pixel value from CVPixelBufferRef in Swift
<p>How can I get the RGB (or any other format) pixel value from a CVPixelBufferRef? Ive tried many approaches but no success yet.</p>

<pre><code>func captureOutput(captureOutput: AVCaptureOutput!,
                   didOutputSampleBuffer sampleBuffer: CMSampleBuffer!,
                   fromConnection connection: AVCaptureConnection!) {
  let pixelBuffer: CVPixelBufferRef = CMSampleBufferGetImageBuffer(sampleBuffer)!
                CVPixelBufferLockBaseAddress(pixelBuffer, 0)
  let baseAddress = CVPixelBufferGetBaseAddress(pixelBuffer)

  //Get individual pixel values here

  CVPixelBufferUnlockBaseAddress(pixelBuffer, 0)
}
</code></pre>
