The GetAudioLanguage method retrieves the language of the specified audio stream within the current title.
Syntax
HRESULT GetAudioLanguage(
ULONG ulStream,
LCID *pLanguage
);
Parameters
ulStream
[in] Audio stream number for the language being retrieved.
pLanguage
[out] Pointer to an LCID that receives the language information.
Return Values
Returns one of the following HRESULT values.
| Return code | Description |
| S_OK | Success. |
| E_INVALIDARG | Invalid argument. |
| E_POINTER | The pLanguage parameter is NULL. |
| E_UNEXPECTED | The DVD Navigator is not initialized. |
| VFW_E_DVD_INVALIDDOMAIN | DVD Navigator is not in a valid domain. |
Remarks
This method does not return languages for menus. It sets the value pointed to by pLanguage to zero if the stream contains an unknown language. Call the Microsoft® Win32® GetLocaleInfo function to create a human-readable string name from pLanguage:
LCID Language;
hr = pDvdInfo->GetAudioLanguage(ulStream, &Language);
if (SUCCEEDED(hr))
{
int cchSize = GetLocaleInfo(Language, LOCALE_SENGLANGUAGE, 0, 0);
TCHAR *szString = new TCHAR[cchSize];
if (szString)
{
GetLocaleInfo(Language, LOCALE_SENGLANGUAGE, szString, cchSize);
/* ... */
delete [] szString;
}
}
