HRESULT GetSubpictureLanguage(

[out] LCID *pLanguage
);
Parameters
- ulStream [in]
-
Number of the subpicture stream for which the language is being retrieved.

|---|---|
|
Success. |
|
Invalid argument. |
|
The DVD Navigator is not initialized or not in a valid domain. |
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; } }
