IDvdControl2::SelectDefaultSubpictureLanguage

The SelectDefaultSubpictureLanguage method sets the default language for subpicture text.

Syntax

  HRESULT SelectDefaultSubpictureLanguage(
  LCID Language,
  DVD_SUBPICTURE_LANG_EXT subpictureExtension
);

Parameters

Language

[in] Locale identifier that specifies the default language.

subpictureExtension

[in] DVD_SUBPICTURE_LANG_EXT enumeration that specifies the default subpicture extension.

Return Values

Returns one of the following values.

Return code Description
S_OK Success.
E_INVALIDARG TLanguage is invalid.
VFW_E_DVD_INVALIDDOMAIN The DVD Navigator filter is not in a valid domain.

Remarks

This method selects the default language and format to use for subpictures and menus when the disc is played. For example, if Language is specified as 0x409 for U.S. English and subpictureExtension is specified as DVD_SP_EXT_Caption_Big, the DVD Navigator tries to show U.S. English text in the "big caption" format in subpictures. If the default language or language extension is not found on a disc, the DVD Navigator selects the closest match.
