IltmfConvert::EstimateOutputBitRate

#include "ltmf.h"

Platform Syntax
C HRESULT IltmfConvert_EstimateOutputBitRate(pConvert, pVal)
C++ HRESULT EstimateOutputBitRate(pVal)

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

Parameters

IltmfConvert *pConvert

Pointer to an IltmfConvert 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 MediaFoundation documentation.

Comments

The returned bit rate depends on the state of the convert 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 conversion settings and the chosen encoding settings.
