<br>内容：你好！<BR><BR>请问你的DivX的压缩IBaseFilter是怎么来的？是CoCreateInstance来的？这样不好吧？<BR><BR>你应该这样：用CLSID_VideoCompressCategory（好像是这样的，查查看吧）然后用ISysEnum一个个的枚举出所有的Codec，发现有FriendlyName叫做"DivX Pro 5.0"之类的,那才是真的IBaseFilter, 然后要用Bind才能得到IBaseFilter, 然后加入IGraphBuilder.<BR><BR>另外，DeleteMediaType这个函数，我也觉得奇怪DX为什么不把他放到库里去，而是在DxUtils.cpp里面，这个函数很短，你干脆把他Ctrl+V过来就可以了。
