IltmmMediaInfo::get_VideoBitCount

#include "ltmm.h"

C Syntax	HRESULT IltmmMediaInfo_get_VideoBitCount(pMediaInfo, BitCount)
C++ Syntax	HRESULT get_VideoBitCount(BitCount)

 

IltmmMediaInfo *pMediaInfo;	/* pointer to an interface */
long * BitCount;	/* pointer to a variable */

Retrieves the bits per pixel value for the current stream in the current source media file.

Parameter	Description
pMediaInfo	Pointer to an IltmmMediaInfo interface.
BitCount	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.
