How to set slider to control video in MATLAB GUI?

I am trying to set a slider in MATLAB GUI to control video like move into some frames of the video. The 'obj' is the video file selected by the user. The following code was used to take the input video and show in an axes of the GUI.

    global b    
    filename = get(handles.edit3, 'String');
      if ~exist(filename, 'file')
        warndlg( 'Text in edit box is not the name of a file');
        return
      end
      try
        obj = VideoReader(filename);
      catch
        warndlg( 'File named in edit box does not appear to be a usable movie file');
        return
      end

    axes(handles.axes2)
    handles.pushbutton5=0;
    guidata(hObject,handles);
    while ~(handles.pushbutton5)
        if hasFrame(obj)
        vidFrame = readFrame(obj);
        obj;
        image(vidFrame, 'Parent', handles.axes2);
        set(axes, 'Visible', 'off');
        pause(1/obj.FrameRate)
        end
        handles = guidata(hObject);
    end
    clear obj

The slider will provide "b" value while the user control the slider. 

function slider2_Callback(hObject, eventdata, handles)
% hObject    handle to slider2 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Hints: get(hObject,'Value') returns position of slider
%        get(hObject,'Min') and get(hObject,'Max') to determine range of slider
global b
 b = get(handles.slider2,'Value');

Does anyone know how solve this problem so that the video can be controlled by the slider?
