VMR9视频叠加寻求媒体
我的两个视频和叠加使用类VMR9Graph.h
CVMR9Graph他们从项目
CVMR9Graph m_graph_overlap;
m_graph_overlap.ReleaseAllInterfaces();
m_graph_overlap.SetMediaWindow(vd);
m_graph_overlap.SetMediaFile(szFileName, 0);
m_graph_overlap.SetLayerZOrder(0, 0);
m_graph_overlap.SetMediaFile(szFileName2, 1);
m_graph_overlap.SetLayerZOrder(1, 2);
m_graph_overlap.SetAlphaLayer(0, 50);
m_graph_overlap.PreserveAspectRatio(FALSE);
m_graph_overlap.PlayGraph();
然后，我获得了一些指针
/ /从CVMR9Graph班为PERFOMING各种媒体事件/ /
指针{C}pMediaControl3=m_graph_overlap.GetPtrMediaControl();
现在我已经implmented的媒体提出寻求功能
{体C3}
它将寻求只有一流的视频和第二个视频暂停..
我想同时寻求双方overalyed的视频...
