matlab下WindowMediaPlayer测试使用

首先我遇到了运行以后无法展示问题

当更改URL时，对应的window player PlayStateChange 增加语句，会加载出来

set(hObject.Peer,'Visible','on');

如果是要程序运行就出现，那么在UI里面的如下函数增加，其中activex3为对应的空间tag号

%% --- Executes just before lrcxjy is made visible.可视化之前运行部分function lrcxjy_OpeningFcn(hObject, eventdata, handles, varargin)% This function has no output args, see OutputFcn.% hObject    handle to figure% eventdata  reserved - to be defined in a future version of MATLAB% handles    structure with handles and user data (see GUIDATA)% varargin   command line arguments to lrcxjy (see VARARGIN)% Choose default command line output for lrcxjyhandles.output = hObject;% Update handles structureguidata(hObject, handles);

set(handles.activex3.Peer,'Visible','on');

我现在还面临没有即使释放资源的问题。还在思考
