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

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);
