            cameraFeed = new byte[data.length];
     System.arraycopy(data, 0, cameraFeed, 0, data.length);

    Use something like above to copy the data from the preview frame in the first thread onPreviewFrame, Then in the second thread access the data rather than accessing any functions of the camera
