#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 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.
