How Can I close a video while playing in MATLAB GUI

The following error I get it while running a code file

Reference to non-existent field 'aviobj'.

Error in final>CloseVideo_Callback (line 287) handles.aviobj

Error in gui_mainfcn (line 96) feval(varargin{:});

Error in final (line 42) gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)final('CloseVideo_Callback',hObject,eventdata,guidata(hObject))

After you assigned a value to handles.aviobj, did you use

guidata(hObject, handles)

to update the master copy of the handles structure?

[Rajesh]

I already assign this but still the error is showing in aviobj non existent file.

Reference to non-existent field 'aviobj'.

I donno what I want to do..plz help

This is my code for closing a video while recording a video..

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

if ~isfield(handles, 'format')

      h = warndlg('Video settings are not ready,  redo it','!! Warning !!');

      pause (5); 

      if ishandle(h), close (h); end;

      return;

end

if isfield(handles, 'vid')

      h = warndlg('Video not closed!','!! Warning !!');

      pause (5); 

      if ishandle(h), close (h); end;

      return;

end

% Update handles structure

   guidata(hObject, handles);

   handles.aviobj

   stop(handles.aviobj)

% close(handles.aviobj)

% delete(handles.aviobj)

   handles = rmfield(handles,'aviobj'); 

   clear handles.aviobj;

%  aviobj = close(aviobj.DiskLogger);

% update handles

handles.output = hObject;

handles.output = hObject

% Update handles structure

guidata(hObject, handles);

[Walter Roberson]

We need the code where you create handles.aviobj

[Image Analyst]

Set a breakpoint on this line:

handles.aviobj

Then type that onto the command line and see what it says. You do not assign handles.aviobj in that function so if it doesn't already exist (already attached to handles) when you enter the function, then I'd think that line would cause an error. If it does exist already, then prove it by showing us the function that attaches aviobj to the handles structure.

it's not working

Finally I getting this error

Warning: AVIREAD will be removed in a future release. Use VIDEOREADER instead.

then Videoreader command not working on MATLAB 2012a...what I do

[Walter Roberson]

Make sure you use VideoReader with capital V and capital R, not lower-case R.

Thank You walter Roberson sir...:-)
