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);  
	sa.pvData = pData;  
	sa.rgsabound[0].cElements = lSize;  
	VariantInit(&var);  
	V_VT(&var) = (VT_ARRAY | VT_UI1);  
	V_ARRAY(&var) = &sa;  
 
	IltmmMemory_SetData(pMemSource, 0, lSize, var);  
 
	IltmmMemory_Release(pMemSource);
