Dahua surveillance video Dav converter avi, dhplay.dll and SDK documentation, ca

Dahua surveillance video Dav converter avi, dhplay.dll and SDK documentation, can realize playing but failed to achieve the conversion of AVI, I have a vc++ demo here, there is a C# demo, but C#demo has no conversion function, I wrote the code conversion not, have done a similar problem? For us.

Part of the code:

 private void button3_Click(object sender, EventArgs e)

        {

            if (ofdMain.FileName == "") return;



            bool b1 = DHPlay.PLAY_SetStreamOpenMode_p(0,1);



            bool b2 = DHPlay.PLAY_OpenStream_p(0, IntPtr.Zero, 0, (UInt32)900 * 1024);



            bool b3=DHPlay.PLAY_StartAVIConvert_p(0, ofdMain.FileName.Replace(".dav", ".avi"), AVIConvertCallback2, 0);



            FileStream SourceFile = File.OpenRead(ofdMain.FileName);

            //if (!SourceFile.Open(m_csSourceFile, CFile.modeRead | CFile.shareDenyNone))

            //{

            //    //PLAY_StopAVIConvert(DefineConstantsAVIConvertDlg.AVICONV_PORT);

            //    //PLAY_Stop(DefineConstantsAVIConvertDlg.AVICONV_PORT);

            //    //PLAY_CloseStream(DefineConstantsAVIConvertDlg.AVICONV_PORT);

            //}

            uint dwFileLen = (uint) SourceFile.Length;

            const int BUFLEN = 8 * 1024;

            byte[] InfoBuf = new byte[BUFLEN];

            uint nRead;

            uint dwCurPos = 0;

           bool m_bAVIConvEnable =true;

            while (m_bAVIConvEnable)

            {

                //memset(InfoBuf, 0, InfoBuf.Length);

                //nRead = SourceFile.Read(InfoBuf, BUFLEN);

                nRead = (uint)SourceFile.Read(InfoBuf,0 ,BUFLEN);

                if (nRead <= 0)

                {

                    break;

                }



                dwCurPos += nRead;



                //////////////////

                //byte[] test = new byte[5];

                GCHandle hObject = GCHandle.Alloc(InfoBuf, GCHandleType.Pinned);

                IntPtr pObject = hObject.AddrOfPinnedObject();



                if (hObject.IsAllocated)

                    hObject.Free();

 

                /////////////////

                while (m_bAVIConvEnable && !DHPlay.PLAY_InputData_p(0, InfoBuf, nRead))//Blocking false

                {

                    Thread.Sleep(5);

                }



                double fpress = (double)dwCurPos / (double)dwFileLen;



                int iProgressPos = (int)(fpress * 1000.0);

                //if (m_bAVIConvEnable)

                //    pProgCtrl->SetPos(iProgressPos);

            }



        }
