IltmfConvert::put_SourceArray

#include "ltmf.h"

C Syntax	HRESULT IltmfConvert_put_SourceArray(pConvert, newVal)
C++ Syntax	HRESULT put_SourceArray(newVal)

 

IltmfConvert *pConvert;	/* pointer to an interface */
VARIANT newVal;	/* value of the array */

Sets the media source to an array of bytes.

Parameter	Description
pConvert	Pointer to an IltmfConvert interface.
newVal	VARIANT containing a reference to a SAFEARRAY of media data. The array should have one dimension and should contain byte elements.

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 a SAFEARRAY and use it as the source for the conversion process. The user is responsible for allocating, initializing, and freeing the array. However, the user should not free the array while the convert object holds a reference to it. The ResetSource function should be called to stop the convert object from accessing the array. The SourceType will be set to ltmfConvert_Source_Array.
