IltmmCapture::EstimateOutputBitRate

Summary

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

Syntax

#include "ltmm.h"

Language Syntax
C HRESULT IltmmCapture_EstimateOutputBitRate(pCapture, pVal)
C++ HRESULT EstimateOutputBitRate(pVal)

Parameters

IltmmCapture *pCapture

Pointer to an IltmmCapture interface.

long *pVal

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

Returns

Value Meaning
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

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.
