IltmmPlay::get_SourceStream Example for C

This method will fill the source stream with data from a buffer.

void IltmmPlay_get_SourceStream_Example (UCHAR *pData, long lSize, IltmmPlay *pPlay) 
{
        IltmmMemory *pMemSource = NULL; 
        SAFEARRAY sa; 
        VARIANT var; 

        HRESULT hr = IltmmPlay_get_SourceStream(pPlay, (IUnknown**)&pMemSource); 

        if(FAILED(hr) || pMemSource == NULL) 
                return; 

        IltmmMemory_put_BufferSize (pMemSource, lSize); 

        // pass data
        memset(&sa, 0, sizeof(sa)); 
        sa.cbElements = sizeof(unsigned char); 
        sa.cDims = 1; 
        sa.fFeatures = (FADF_AUTO | FADF_FIXEDSIZE);

        IltmmMemory_SetData(pMemSource, 0, lSize, var); 

        IltmmMemory_Release(pMemSource);
