调用directshow出现链接错误，如何解决？

player.obj : error LNK2001: unresolved external symbol _IID_IVideoWindow

player.obj : error LNK2001: unresolved external symbol _IID_IMediaControl



这是因为链接器没有找到合适的.lib文件。两种办法：

1、在EVC菜单Tools—options—directories 里把library files的路径重新调整一下。如果你只安装了EVC自带的 Standard SDK而没有其它SDK，可以指定WINCE目录中的.lib文件路径，例如D:\WINCE500\PUBLIC\DIRECTX\ OAK\LIB\X86\RETAIL。注意CPU的类型。

2、安装SDK，前提是导出SDK的PB内核工程必须包括DirectShow或者其它组件。

In two ways: 1, in the EVC menu Tools-options-directories in the path of the library files to re-adjust. If you only installed the Standard SDK EVC own and not the other SDK, you can specify the directory in WINCE. Lib file path, for example D: \ WINCE500 \ PUBLIC \ DIRECTX \ OAK \ LIB \ X86 \ RETAIL. Note CPU type. 2, the installation of SDK, SDK, provided that the PB cores derived works must include the DirectShow or other components.
