  Hello Hariosmk154,

   

  Please add align object and apply it in opencv_viewer_example.py:

  # Configure depth and color streams
  pipeline = rs.pipeline()
  config = rs.config()
  config.enable_stream(rs.stream.depth, 1024, 768, rs.format.z16, 30)
  config.enable_stream(rs.stream.color, 1280, 720, rs.format.bgr8, 30)
  
  # Align objects
  align_to = rs.stream.color
  align = rs.align(align_to)
  
  # Start streaming
  pipeline.start(config)
  
  try:
      while True:
          # Wait for a coherent pair of frames: depth and color
          frames = pipeline.wait_for_frames()
          aligned_frames = align.process(frames)
          depth_frame = aligned_frames.get_depth_frame()
          color_frame = aligned_frames.get_color_frame()

  private void configAndStart() throws Exception {
  try(Config config = new Config())
  {
  config.enableStream(StreamType.DEPTH, 640, 480);
  config.enableStream(StreamType.COLOR, 640, 480);
  // try statement needed here to release resources allocated by the Pipeline:start() method
  config.enableAllStreams();// add this code,it will work!!!!!
  Log.e(TAG, "configAndStart: ok 1");
  try(PipelineProfile pp = mPipeline.start(config)){
  Log.e(TAG, "configAndStart: ok 2");
  }catch (Exception e){
  e.printStackTrace();
  }
  }catch (Exception e){
  e.printStackTrace();
