title: Fast way to decode JPEG image
body: <p>I need to decode (unpack into bitmap) pretty small (about 1200 * 1200) JPEG. The problem is I need to do it quickly. I have tried libjpeg, and it's quite slow. I have also tried BitmapFactory.decodeByteArray - it's a bit faster, but still not fast enough. What are another options?
  A native (C++) library is much preferred.</p>
  
  <p>P.S. My JPEGs are created directly in memory. </p>
  
  <p>P.P.S. I wonder how come libjpeg is slower than BitmapFactory.decodeByteArray.</p>
