我现在想直接从采集卡上实时截图,但卡上有TV端,av端,s端,我想编程设定,不知怎么弄,
后来就想用系统的菜单来设定:
CapEnum.SelectGUIDCategory(CLSID_VideoinputDeviceCategory);
Filter.BaseFilter.Moniker := CapEnum.GetMoniker(0);
Filter.FilterGraph := CaptureGraph;
CaptureGraph.Active := true;
ShowFilterPropertyPage(Self.Handle, Filter as IBaseFilter);
但这个菜单只能设定输入格式,我想调crossbar菜单,不知怎么弄,请高手指教!或能用
其它办法也成!
