Show in webframe

#include "ltmm.h"

C Syntax	HRESULT IltmmCompressor_get_Name(pCompressor, pVal)
C++ Syntax	HRESULT get_Name(pVal)

IltmmCompressor *pCompressor;	/* pointer to an interface */
BSTR *pVal;	/* string */

Retrieves the compressors unique name.

Parameter	Description
pCompressor	Pointer to an IltmmCompressor interface.
pVal	Pointer to a character string containing the compressors name.

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

The returned string can be used to uniquely identify a compressor . A program can save this value to persistent storage and used later with the ltmmCompressors::Find function to restore the compressor selection.

If the method succeeds, the caller must free the returned BSTR by calling the SysFreeStringSysFreeString function.
