DirectShow的GraphEdit中 点Insert Filters 在其下拉菜单中点击DirectShow Filter后整个GraphEdit全部消失
这种情况怎么解决？（之前生成并注册了dsnet.ax，要使用到DirectShow Filter下的过滤器） 情况紧急 求解决。
[解决办法]
注册了LAVVideo.ax也会出现这样的情况，据说是GraphEdit的bug
Q: GraphEdit crashes after i installed LAV Video!
A: This is a GraphEdit bug. It will crash as soon as one filter supports more then 100 formats. There is nothing to be done. Personally, i suggest using GraphStudio instead!
