IltmfCapture::EstimateOutputBitRate

Summary

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

Syntax

#include "ltmf.h"

Parameters

IltmfCapture *pCapture

Pointer to an IltmfCapture interface.

long *pVal

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

Returns

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.
