IltmmConvert::put_SourceHGlobal

#include "ltmm.h"

C Syntax	HRESULT IltmmConvert_put_SourceHGlobal(pConvert, newVal)
C++ Syntax	HRESULT put_SourceHGlobal(newVal)

 

IltmmConvert *pConvert;	/* pointer to an interface */
long newVal;	/* source media data handle */

Sets the media source to a global memory handle.

Parameter	Description
pConvert	Pointer to an IltmmConvert interface.
newVal	Handle to the global memory (HGLOBAL) containing the source media data.

Returns

S_OK	The function was successful.
<> S_OK	An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation.

Comments

This function allows the user to store a complete media file in global memory and use it as the source for the conversion process. The user is responsible for allocating, initializing, and freeing the global memory. However, the user should not free the global memory handle while the convert object holds a reference to it. The ResetSource function should be called to stop the convert object from accessing the global memory. The SourceType will be set to ltmmConvert_Source_HGlobal.
