IltmmMediaInfo::get_VideoBitRate

#include "ltmm.h"

C Syntax

HRESULT IltmmMediaInfo__get_VideoBitRate(pMediaInfo, BitRate)

C++ Syntax

HRESULT get_VideoBitRate(BitRate)

 

IltmmMediaInfo *pMediaInfo;

/* pointer to an interface */

long * BitRate;

/* pointer to a variable */

Retrieves the video bit rate, in bits per second, for the current stream in the current source media file. The video bit rate refers to the video data transfer rate.

Parameter

Description

pMediaInfo

Pointer to an IltmmMediaInfo interface.

BitRate

Pointer to a variable that receives the bits per pixel value.

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

This function will fail if the current stream is not a video stream The portion of the file holding the video data. The video data might be compressed to save disk space. The data has to be decompressed using a video decompressor Also known as a decoder, this is a module or algorithm to decompress data. before you can play (see) it..

The current source media file, set using IltmmMediaInfo::put_SourceFile, is the file for which the IltmmMediaInfo interface/object gets information. IltmmMediaInfo::put_SourceFile must be called before calling any of the other IltmmMediaInfo functions used for retrieving information.

To set the current stream, call IltmmMediaInfo::put_CurrentStream.
