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
Currently, the toolkit does not recommend compressors for all formats, so if the returned string is empty, then there is no recommended audio compressor for the selected target format.
If the method succeeds, the caller must free the returned BSTR by calling the SysFreeString function.
