【急急急！！】c#用directshow做播放器，播放视频文件时renderfile出错，

FF_chuliu 2015-11-12 12:15:10

在播放音频文件时没有问题
但是播放视频文件时，在renderfile那里就出错
报错是：
“System.Runtime.InteropServices.COMException”类型的未经处理的异常出现在 DSPlayer.exe 中。
其他信息: 异常来自 HRESULT:0x80040216

怎么解决啊，求大神帮忙



        public void selectIndexChanged(){

            fName = Convert.ToString(listBox1.SelectedItem);

            fName = fPath + "\\" + fName;

            playMedia(fName);

        }

       private void playMedia(String fName) {

            cleanUp();

            m_objFilterGraph = new FilgraphManager();

            m_objFilterGraph.RenderFile(fName);

            m_objBasicAudio = (IBasicAudio)m_objFilterGraph;

            m_objBasicVideo = (IBasicVideo)m_objFilterGraph;

            try

            {

                m_objVideoWindow = (IVideoWindow)m_objFilterGraph;

                m_objVideoWindow.Owner = (int)splitContainer1.Panel1.Handle;

                m_objVideoWindow.WindowStyle = WS_CHILD | WS_CLIPCHILDREN;

                m_objVideoWindow.SetWindowPosition(splitContainer1.Panel1.ClientRectangle.Left, splitContainer1.Panel1.Top,            m_objBasicVideo.VideoWidth, m_objBasicVideo.VideoHeight);

                splitContainer1.Height = m_objBasicVideo.VideoHeight + panel1.Height;

                splitContainer1.Width = m_objBasicVideo.VideoWidth + splitContainer1.Panel2.Width + 4;

            }

            catch (Exception)

            {

                m_objVideoWindow = null;

            }
