IltmfPlay::put_SourceHGlobal

#include "ltmf.h"

C Syntax	HRESULT IltmfPlay_put_SourceHGlobal(pPlay, newVal)
C++ Syntax	HRESULT put_SourceHGlobal(newVal)

 

IltmfPlay *pPlay;	/* pointer to an interface */
long newVal;	/* media data handle */

Sets the media source to a global memory handle.

Parameter	Description
pPlay	Pointer to an IltmfPlay interface.
newVal	Handle to the global memory (HGLOBAL) containing the 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 MediaFoundation documentation.

Comments

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