Return codeDescription

Success.

E_INVALIDARG

Invalid argument.

Remarks

To get the text languages available for a menu, call GetMenuLanguages. GetSubpictureLanguage sets the value pointed to by pLanguage to zero if the stream contains an unknown language. Call the Win32 GetLocaleInfo function as follows to create a human-readable string name from pLanguage:



LCID Language;
hr = pDvdInfo->GetSubpictureLanguage(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;
    }
}
