Problem

[Anderl]

Hey guys,

This may not be the right place to ask what I need but I already searched on forums/Google about this problem and I didn't find anything. Also no one wants to help .__.

So here we go:

I'm making some test apps/games in C++ and I just wanted to render a video when the game starts but it does not seem to be working like I wanted.

Here is the function:

int DirectX9::renderIntro( LPCWSTR filePath, HWND hWnd ) 
{ 
    // declare variables 
    IGraphBuilder* pGraph = NULL; 
    IMediaControl* pControl = NULL; 
    IMediaEvent* pEvent = NULL; 
    IVideoWindow* pVidWin = NULL; 
  
    // initialize COM library 
    HRESULT hrInitialize = CoInitialize( NULL ); 
    if( FAILED( hrInitialize ) ) 
    { 
        MessageBox( NULL, L"Unable to initialize COM library.", L"Warning", NULL ); 
        return 1; 
    } 
  
    // create filter 
    HRESULT hrFilter = CoCreateInstance 
    (  
        CLSID_FilterGraph, NULL, CLSCTX_INPROC_SERVER, 
        IID_IGraphBuilder, (VOID**) &pGraph 
    ); 
    if( FAILED( hrFilter ) ) 
    { 
        MessageBox( NULL, L"Unable to create filter to render video.", L"Warning", NULL ); 
        return 1; 
    } 
     
    hrFilter = pGraph->QueryInterface( IID_IMediaControl, (void**)&pControl ); 
    hrFilter = pGraph->QueryInterface( IID_IMediaEvent, (void**)&pEvent ); 
    hrFilter = pGraph->QueryInterface( IID_IVideoWindow, (void**)&pVidWin ); 
  
    pVidWin->put_Owner( (OAHWND)hWnd ); 
    pVidWin->put_WindowStyle( WS_CHILD | WS_CLIPSIBLINGS ); 
    //pVidWin->SetWindowPosition( 0, 0, 500, 400 ); 
    //pVidWin->put_MessageDrain( (OAHWND)hWnd ); 
    pVidWin->put_Visible( 1 ); 
    pVidWin->put_FullScreenMode( 1 ); 
  
    // render video 
    HRESULT hrVideo = pGraph->RenderFile( filePath, NULL ); 
    if( SUCCEEDED( hrVideo ) ) 
    { 
        // run video 
        HRESULT hrVide = pControl->Run(); 
        if( SUCCEEDED( hrVide ) ) 
        { 
            HRESULT hrIntroDone = pEvent->WaitForCompletion( INFINITE, &evCode ); 
            switch( hrIntroDone ) 
            { 
                case S_OK: 
                    hrVide = pControl->Stop(); 
                    exit(0); 
                    break; 
                case E_ABORT: 
                    exit(0); 
                    break; 
                default: 
                    exit(0); 
                    break; 
            } 
        } 
    } 
    else 
    { 
        MessageBox( NULL, L"Unable to load video file.", L"Warning", NULL ); 
        switch( hrVideo ) 
        { 
            case S_OK: 
                MessageBox( NULL, L"Everything ok.", L"Warning", NULL ); 
                break; 
            case VFW_S_AUDIO_NOT_RENDERED: 
                MessageBox( NULL, L"Audio not rendered.", L"Warning", NULL ); 
                break; 
            case VFW_S_DUPLICATE_NAME: 
                MessageBox( NULL, L"Filter duplicated name.", L"Warning", NULL ); 
                break; 
            case VFW_S_PARTIAL_RENDER: 
                MessageBox( NULL, L"Stream not supported.", L"Warning", NULL ); 
                break; 
            case VFW_S_VIDEO_NOT_RENDERED: 
                MessageBox( NULL, L"Some part not rendered.", L"Warning", NULL ); 
                break; 
            case E_ABORT: 
                MessageBox( NULL, L"Aborted.", L"Warning", NULL ); 
                break; 
            case E_FAIL: 
                MessageBox( NULL, L"Failure.", L"Warning", NULL ); 
                break; 
            case E_INVALIDARG: 
                MessageBox( NULL, L"Invalid arguments", L"Warning", NULL ); 
                break; 
            case VFW_E_INVALID_FILE_FORMAT: 
                MessageBox( NULL, L"File format invalid.", L"Warning", NULL ); 
                break; 
            case VFW_E_NOT_FOUND: 
                MessageBox( NULL, L"File not found.", L"Warning", NULL ); 
                break; 
        } 
        exit(0); 
    } 
    // release and free memory 
    pControl->Release(); 
    pEvent->Release(); 
    pGraph->Release(); 
    CoUninitialize(); 
    return 0; 
  
} 

I call that function in the "renderStuff" function with this:

    // render intro 
    char szPath[MAX_PATH]; 
    GetFullPathName( L"movies\\GTAmovie.mpg", sizeof( szPath ), (LPWSTR)szPath, NULL );  
    if( !DirectX3D->renderIntro( (LPCWSTR)szPath, hWnd ) ) 
    { 
        exit(0); 
    } 

The problem is that: The video loads in a new window but I want it in the same window...

As you can see, I used "pVidWin->put_FullScreenMode( 1 )" and it didn't work

Should I use other renderer? If so, what renderer should I use? Should I use VMR-9 with Windowless mode?

[Anderl]

Problem solved.

Lock this topic.

[Castillo]

There's no need to lock it.

How did you fix it?

[Anderl]

How did you fix it?

I forgot that I have to render the movie first

[qaisjp]

// render video 
    HRESULT hrVideo = pGraph->RenderFile( filePath, NULL ); 

then what was that

[Anderl]

I mean, I have to render the movie before set parent window. I only remembered that when I checked result of "pVidWin->put_Owner( (OAHWND)hWnd );".

[qaisjp]

Okay...
