Retrieves the calculated bit rate of the current source media file, in bits per second.
|C||HRESULT IltmmMediaInfo_get_SourceBitRate(pMediaInfo, pVal)|
Pointer to an IltmmMediaInfo Interface.
Pointer to a variable to be updated with the calculated bit rate of the current source media file, in bits per second.
|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.|
The bit rate obtained by this function is calculated as follows:
BitRate = (FileSize * 8) / SourceDuration
To get the current source media file, call IltmmMediaInfo::get_SourceFile.
The current source media file, set using IltmmMediaInfo::put_SourceFile, is the file for which the IltmmMediaInfo interface/object gets information. This function must be called before calling any of the other IltmmMediaInfo functions used for retrieving information.
Call IltmmMediaInfo::ResetSource to release the source file when it is no longer needed.
