Loop .mp3 playback

Reply Quote

I'm very new to audio. I stumbled across the following code and I'm using the it to play audio .mp3s in my DX9.0 app. ( Nov 08 SDK )

    
            ::CoInitialize(NULL);  
        
            CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC, IID_IGraphBuilder, (void **)&g_pGraphBuilder);  
        
            g_pGraphBuilder->QueryInterface(IID_IMediaControl, (void **)&g_pMediaControl);  
        
            g_pGraphBuilder->AddSourceFilter(L"../Media/Audio/Music/Artifact_CharMain.mp3", L"../Media/Audio/Music/Artifact_CharMain.mp3", &pSource);  
        
            pSource->FindPin(L"Output", &pPin);   
        
            g_pGraphBuilder->Render(pPin);  
        
            pPin->Release();  
        
            g_pMediaControl->Run();

How can I make the .mp3 loop?

Thanks!

try with this:

    
            IMediaEventEx *mediaevent;   
        
            IMediaSeeking *mediaseeking;
        
            g_pGraphBuilder->QueryInterface(IID_IMediaEventEx, (void **)&mediaevent);
        
            g_pGraphBuilder->QueryInterface(IID_IMediaSeeking, (void **)&mediaseeking);
        
            long evCode, param1, param2;  
        
            mediaevent->FreeEventParams(evCode, param1, param2);
        
            if(EC_COMPLETE == evCode)   {
        
            g_pMediaSeeking->SetPositions(0,AM_SEEKING_AbsolutePositioning, 0, AM_SEEKING_NoPositioning); 
        
            gControl[i]->Run();   }

hope it helps...
