Hi Everyone, Actually I like to use the GPL MPEG1/2 decoder from the follwing site http://www.free-codecs.com[^] I have the decoder source which gives GPLDec.lib and GPLDec.ax files. I had registered the GPLDec.ax file so that I can see that in Graphedit,but can anyone tell me how do I include the GPL MPEG1/2 Decoder in my own graph with the help of the IBaseFilter interface? And also the CLSID mentioned in the source is "CLSID_GpgMpegDecoder" ..When I try to add this with ADDFilterByCLSID(...) function I an getting a "Undefined Symbol" error as there is no header file given to access the GPLDec.lib file. So can anyone help me with this? Thank You, With regards

Hi Rajesh, Thank you very much for replying, As you said in the following case IGraphBuilder* g_pGraphBuilder; IBaseFilter *MyFilter; HRESULT hr hr=AddFilterByCLSID(g_pGraphBuilder,CLSID_VideoRenderer,NULL,&VideoRendrer); CLSID_VideoRenderer this one is not known to me. The classid like 2345-2445-3245-543456 (for example CLSID_VideoRenderer = 2345-2445-3245-543456)which I got from DxFilterSpy.exe is known to me. So can you tell me how do I add this Classid in my application and relate it to my base class filter Awaiting for your reply Thank You With regards

hi guys, I designed the MCI player for playing file formats like mpeg 1, mpeg 2(m2p extension),vob.....In that I am able to play all the file formats BUT i am unable to get the total time duration for the mpeg 2 files(m2p extension) alone using LONG MCIWndGetLength(HWND) function(for other formats the time duration is complete and i dont have problem ). The length obtained from this function doesnt match with the total duration of the mpeg 2 file alone(extension m2p). Some part of the m2p file at the end are missing(around 5 seconds in a 12 seconds m2p file). Can anyone help me to solve this problem??? Thank you. With regards

Raja Bose

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

Raja Bose

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

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...
