无法从Kinect获取深度数据

Question

I've been messing about all day trying to get the (raw) data from the Kinect with no success.

I've been trying to hack the unit tests into a program of sorts and my Google-fu is letting me down - I couldn't find any other Java examples anywhere on the web using Java/JNA/osX.

This is the test that I've been hacking at but just can't seem to get a method to extract the frame data.

 @Test
 public void testDepth() throws InterruptedException {
    assumeThat(dev, is(not(nullValue())));

    final Object lock = new Object();
    final long start = System.nanoTime();
    System.out.println(dev.getDepthMode());
    //dev.startDepth(new DepthHandler(){});
    dev.startDepth(new DepthHandler() {
        int frameCount = 0;

        @Override
        public void onFrameReceived(FrameMode mode, ByteBuffer frame, int timestamp) {

            //ByteBuffer frame1 = frame;
            frameCount++;
            byte[] b = new byte[frame.remaining()];
            System.out.println(frameCount);
            System.out.println(frame.capacity());
            //System.out.println(frame.);
            if (frameCount >= 300) {
                synchronized (lock) {
                    lock.notify();
                    System.out.format("Got %d depth frames in %4.2fs%n", frameCount,
                            (((double) System.nanoTime() - start) / 1000000000));
                }
            }
        }
    });
    synchronized (lock) {
        lock.wait(20000);
    }
}  

Any help is much appreciated.

Take a look at this project: https://github.com/murphydactyl/JavaKinectFingerTracker

The getDepthFrame function gives you the Depth data in a usable form: https://github.com/murphydactyl/JavaKinectFingerTracker/blob/9ed9fcb7836276f7ac9c2bf25569c68417158df5/kinectdigitizer/KinectFrameGrabber.java

If you try to run it with the newest version of the jna it won't work; the onFrameReceived function changed a bit.
