title: How can I convert kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange data to YUV420P?
body: <p>I'm capturing output from iPad camera and then sending it to a server. I'm new to image processing etc. so I'm learning a lot as I go. </p>
  
  <p>The server needs to receive in YUV420P. Right now all I get is the frame in grayscale pretty much. I'm guessing that's the bi-planar vs planar. </p>
  
  <p>How can I convert data from the camera using the kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange data type into YUV420P frames?</p>
