IDvdControl::TopPGSearch method (strmif.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
Syntax
HRESULT TopPGSearch();
Return value
Returns an HRESULT value .
Remarks
A program is usually equivalent to a chapter, and a PGC is usually equivalent to a title. In the case of One_Sequential_PGC_Titles, each program is required to be a chapter and each title has only one PGC, but in other cases (especially with random/shuffle PGCs and parental blocks) there can be more than one program between chapters and there can be more than one PGC in a title.
This method returns an error unless the domain is DVD_DOMAIN_VideoManagerMenu, DVD_DOMAIN_VideoTitleSetMenu, or DVD_DOMAIN_Title. For more information, see DVD_DOMAIN.
