IDvdControl::PrevPGSearch

  • Note   The IDvdControl interface is deprecated. Use IDvdControl2 instread.

Halts playback of the current program and starts playback from the previous program within the program chain (PGC).

Syntax

  HRESULT PrevPGSearch(void);

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.

Requirements

Reference: Dshow.h.

Library: Quartz.dll.
