title: Converting Unity's RGBA array to YUV byte array
body: <p>Unity's <code>Texture.GetPixels32()</code> gives us a <code>Color32[]</code>, which is an RGBA array that can be converted easily into <code>byte[]</code>. </p>
  
  <p>How can we convert this <code>Color32[]</code> or RGBA <code>byte[]</code> into a YUV <code>byte[]</code>?</p>
  
  <p>Also, how does the Alpha value affect the YUV conversion? Online, I mostly see people only trying to convert RGB to YUV. Thanks!</p>
