#include "ltmf.h"

C Syntax

HRESULT IltmfCapture_EstimateOutputBitRate(pCapture, pVal)

C++ Syntax

HRESULT EstimateOutputBitRate(pVal)

IltmfCapture *pCapture;

pointer to an interface

long *pVal;

pointer to a variable

Retrieves the estimated capturing output bit rate, in bits per second.

Parameter

Description

pCapture

Pointer to an IltmfCapture interface.

pVal

Pointer to a variable to be updated with the estimated output bit rate.

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

The returned bit rate depends on the state of the capture object.

If the object is in the running state, the returned bit rate is related to the actual number of bytes that have been written.

While if the object is not running, the returned bit rate is a theoretical value dependent on the capturing settings and the chosen encoding settings.
