Die MS-Doku dazu hab ich auch schon mehrfach durch und ist ja auch recht gut im DSPack für Delphi adaptiert.
Ab wie das immer so ist, wenn man den Wald vor lauter Bäumen nicht sieht .... hab nun doch was passendes gefunden:
Aus 'DVDInfo.GetDVDVolumeInfo' kann man die Anzahl der verfügbaren Titel lesen und
mit 'DVDInfo.GetNumberOfChapters' die Kapitel je Titel.
Spiel man nach der DVD-Initialisierung (erst dann !) mittels 'DVDControl.PlayChapterInTitle' jedes vorhandene Kaitel einmal kurz an, kann man mit 'DvdInfo.GetCurrentLocation' und 'DvdInfo.GetTotalTitleTime' die Spieldauer jedes Kapitels und bzw. oder die Gesamtdauer auslesen.
Hier mal meine kleine Routine dazu:
Delphi-Quellcode:
procedure TDVDctrl.GetVolumeInfo();
var
numVol : cardinal;
actVol : cardinal;
side : TDVDDiscSide; // DVD_SIDE_A, DVD_SIDE_B
numTitles : cardinal;
Flags : cardinal;
numChaps : cardinal;
TCFlags : cardinal;
DvdCmd : IDvdCmd;
PBloc : TDVDPlayBackLocation2;
totalTime : TDVDHMSFTimeCode;
i, ii : integer;
begin
FDVDInfo.GetDVDVolumeInfo(numVol, actVol, side, numTitles);
Log('VolInfo', 'Num. of volumes: ' + inttostr(numVol));
Log('VolInfo', 'Actual volume: ' + inttostr(actVol));
Log('VolInfo', 'Num. of sides: ' + inttostr(ord(side)));
Log('VolInfo', 'Num. of titles: ' + inttostr(numtitles));
Flags := DVD_CMD_FLAG_Flush;
for i := 1 to numtitles do
begin
FDVDInfo.GetNumberOfChapters(i, numChaps);
Log('VolInfo', 'Title: ' + inttostr(i) + ' - num chapters: ' + inttostr(numchaps));
for ii := 1 to numChaps do
begin
FDVDControl.PlayChapterInTitle(i, ii, Flags, DvdCmd);
FDvdInfo.GetCurrentLocation(PBloc);
FDvdInfo.GetTotalTitleTime(TotalTime, TCFlags);
Log('VolInfo', ' - Chapter ' + inttostr(pbloc.ChapterNum) +
' / ' + inttostr(pbloc.TitleNum) +
' - Pos: ' + format('%.2d:%.2d:%.2d',[pbloc.TimeCode.bHours,
pbloc.TimeCode.bMinutes,
pbloc.TimeCode.bSeconds]) +
' | Total: ' + format('%.2d:%.2d:%.2d',[TotalTime.bHours,
TotalTime.bMinutes,
TotalTime.bSeconds]));
end;
end;
FDVDControl.PlayChapterInTitle(1,1, Flags, DvdCmd); // ... start from begin
end;
Das Ergebnis sieht dann z.B. so aus:

Schön wäre es jetzt noch zu wissen, welcher Titel was auf der DVD ist, zum VideoManager oder VideoTitleSet-Menu gehört, bzw. (nur) ein SubPicture und nur zu den Menüs gehört.
Das könnte man ggf. zwar aus aus den Zeiten ableiten, ....
Das offenbart sich hier (jedenfalls z. Zt.) erst, wenn man durch die DVD manoveriert und die passenden Events (z.B. EC_DVD_DOMAIN_CHANGE, EC_DVD_TITLE_CHANGE, EC_DVD_STILL_ON/OFF) abfragt.
Eine Herleitung scheint nicht sinnig - hier ist Titel 11 das 'Play-Menü' - und offensichtlich abhängig vom Authoring der DVD.
Oder weiß jemand mehr Details ?
