IltmmWMStreamConfig::put_BufferWindow

#include "ltmm.h"

C Syntax	HRESULT IltmmWMStreamConfig_put_BufferWindow(pStreamConfig, newVal)
C++ Syntax	HRESULT put_BufferWindow(newVal)

IltmmWMStreamConfig *pStreamConfig;	/* pointer to an interface */
long newVal;	/* latency */

Sets the latency in milliseconds between the stream reception and display.

Parameter	Description
pStreamConfig	Pointer to an IltmmWMStreamConfig interface.
newVal	The latency value, in milliseconds, to set.

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

Use a value of ©1 to indicate an unknown latency. The larger the buffer window, the higher the quality in the case of video streams. However, it is not recommended to have streams that have widely different latencies.

You must call IltmmWMProfile::ReconfigStream to use the new value.

For more information, refer to the Microsoft documentation for IWMStreamConfig::SetBufferWindow .
