L LeeChange Unregistered / Unconfirmed GUEST, unregistred user! 2003-04-21 #2 GraphBuilder.QueryInterface(IID_IAMVideoProcAmp, AMVideoProcAmp); AMVideoProcAmp.Set(VideoProcAmp_Brightness, NewValue, 1);
GraphBuilder.QueryInterface(IID_IAMVideoProcAmp, AMVideoProcAmp); AMVideoProcAmp.Set(VideoProcAmp_Brightness, NewValue, 1);
U u2m Unregistered / Unconfirmed GUEST, unregistred user! 2003-04-22 #5 GraphBuilder.QueryInterface(IID_IAMVideoProcAmp, AMVideoProcAmp);这句话就 失败了,可能我的不支持此接口,怎么让它支持阿
L LeeChange Unregistered / Unconfirmed GUEST, unregistred user! 2003-04-22 #6 hehe,你是不是只是在播放呀,IAMVideoProcAmp好象是给Capture Filter用的.
L LeeChange Unregistered / Unconfirmed GUEST, unregistred user! 2003-04-22 #8 呵呵,方法到是有一个,不过好象太复杂, 我想应该有更简单的办法.
U u2m Unregistered / Unconfirmed GUEST, unregistred user! 2003-04-22 #9 只要能解决就行,讲讲思路阿,我还可以加分的,呵呵,我愁死了
