function pushbutton6_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton6 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
  [chosenfile, chosenpath] = uigetfile('*.mp4', 'Select a video');
  if ~ischar(chosenfile)
    return;   %user canceled dialog
  end
  filename = fullfile(chosenpath, chosenfile);
  set(handles.edit50, 'String', filename);

% --- Executes on button press in Start Button.
function pushbutton7_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton7 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

   filename = get(handles.edit50, '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
      axes1 = handles.axes1;
      obj = VideoReader(filename);
      while hasFrame(obj)
          vidFrame = readFrame(obj);
          image(vidFrame, 'Parent', axes1);
          set(axes1, 'Visible', 'off');
          pause(1/obj.FrameRate);
      end
      clear obj
