The GetSubpictureLanguage method retrieves the language of the specified subpicture stream within the current title.
Syntax
HRESULT GetSubpictureLanguage(
ULONG ulStream,
LCID *pLanguage
);
Parameters
ulStream
[in] Number of the subpicture stream for which the language is being retrieved.
pLanguage
[out] Pointer to an LCID that receives the locale information. The language information can then be extracted from the LCID by using the Win32 MAKELANGID macro.
Return Values
Returns one of the following HRESULT values.
| Return code | Description |
| S_OK | Success. |
| E_INVALIDARG | Invalid argument. |
| VFW_E_DVD_INVALIDDOMAIN | 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. LOCALE_SENGLANGUAGE is the locale information type, pszString is a pointer to a buffer to receive the requested data, and cbSize specifies the size of pszString.
GetLocaleInfo(*pLanguage, LOCALE_SENGLANGUAGE, pszString, cbSize);
