Query about MCI(Media Control Interface)
-
hi everyone, I used the MCI controls to play the video files... I can able to play *.vob *.dat *.mpg files but the problem i was facing is that I am NOT able to play mpeg 2 files with m2p extensions .... Can anyone tell me whether MCI supports m2p format files? Thanks in advance With regards

If you set lpstrDeviceType to
MCI_DGV_OPEN_PARMS mciOpen; mciOpen.lpstrDeviceType ="MPEGVIDEO2";what happens?

First of all I like to thank you for replying for my message . I dont know where to use your code MCI_DGV_OPEN_PARMS mciOpen; mciOpen.lpstrDeviceType ="MPEGVIDEO2"; Can you help me with this... I traced the application and found out that i am getting the error while calling this function MCIWndCreate(.....) Code Sample :::::::::::::::::::: HWND CSampleMCI::Initialize() { if((c_Player=MCIWndCreate(hwndParent,AfxGetInstanceHandle(), WS_CHILD | WS_VISIBLE | MCIWNDF_NOTIFYALL | MCIWNDF_NOAUTOSIZEWINDOW |MCIWNDF_NOAUTOSIZEMOVIE|MCIWNDF_NOTIFYERROR|MCIWNDF_SHOWALL , m_sPath))==0) MessageBox("Error in initialise"); MCIWndSetTimeFormat(c_Player,"ms"); MCIWndSetActiveTimer(c_Player,100); lVolume=GetVolume(); return c_Player; } Thank you very much Awaiting for your reply... With regards

Thank you one again for replying hmmm Its giving the same error message (The error message is "The Specified file cannot be played in the specified MCI device. The file may be corrupt, not in correct format or no file name")... I found out one thing that your code had suceeded without error by checking the return value(as given below) ... and also I created a registry value( in regedit) for MPEGVIDEO2 in MCI32 key folder and set the value as MCIQTZ32.DLL is that OK??? .... for MPEGVIDEO I have the key already(so mpeg 1 is playing fine with MCIFMP32.DLL in registry) but for the MPEGVIDEO2 I created new one .... If I didnt create this key, your code returns some error message as their is no DLL linked with MPEGVIDEO2 Devicetype I had included your code in my btnPlay() function in the main dialog is that OK ??? The code snippet for the button play is as follows void CSeamlessPlayerDlg::OnBtnPlay() { if(index == m_PlyLst.GetItemCount()) index=0; char lpszErr[256]; CString SPath=m_PlyLst.GetItemText(index,2); char lpPath[256]; strcpy(lpPath, SPath); /////////////////////////////////////////////////////////////////////////////////// MCI_DGV_OPEN_PARMS mciOpen; mciOpen.dwCallback = 0L; mciOpen.wDeviceID = 0; mciOpen.dwStyle = WS_CHILD; mciOpen.hWndParent = m_hWnd; mciOpen.lpstrElementName = lpPath ; mciOpen.lpstrDeviceType ="MPEGVIDEO2"; mciOpen.lpstrAlias ="MPEGVIDEO2"; MCIERROR err = mciSendCommand( 0,MCI_OPEN, (DWORD)(MCI_OPEN_ELEMENT|MCI_OPEN_TYPE |MCI_DGV_OPEN_PARENT|MCI_DGV_OPEN_WS),(DWORD)(LPVOID)&mciOpen); if(err != 0) { mciGetErrorString(err, lpszErr,256); MessageBox(lpszErr); // display error if failed } //////////////////////////////////////////////////////////////////////////////////// if(m_PlyLst.GetItemCount() != 0) { // mci.Stop(); mci.SetPath(SPath); mci.SetParent(m_video.GetSafeHwnd()); mci.Initialize(); // mci.SetParent(m_video.GetSafeHwnd()); // if(i==m_PlyLst.GetItemCount()) // mci.Initialize(); ::ShowWindow(mci.GetWindowHandle(),SW_MAXIMIZE); mci.Play(); SetTimer(1,1000,NULL); } else { MessageBox("Check your Play List"); } } Thank you, Awaiting for your reply:) With regards

I think you are new on MCI for example if you need to a HWND handle you can see
MCI_DGV_STATUS_HWND(MCI_STATUS) if I guess is true see examples on codeprojext about MCI but for play you can use ofMCI_DGV_PLAY_PARMS mciPlay; mciPlay.dwFrom = mciPlay.dwTo = 0; mciPlay.dwCallback = MAKELONG(hWnd,0); mciSendCommand(/*its return of openmci that you need to get it*/DeviceID, MCI_PLAY,MCI_NOTIFY,(DWORD)&mciPlay);:)

Thank you once again for replying I had refered a sample "EY player" from code project and I developed my own application using MCI ... and also i am new to MCI.... Actual problem I am getting is that I am not able to play MPEG 2 files alone(with extension m2p and mp2)... It is working fine with mpeg 1, vob, avi and dat files.... hmmmm ok as you had said I will see some more samples from code project and if I have anymore doubt i will contact you... Thank you With Regards
