TWindowsMediaPlayer in Delphi 7 benutzen

[kwhk]

Ich habe TWindowsMediaPlayer installiert entsprechend der Hinweise in folgendem Link
http://www.entwickler-ecke.de/topic_...0.html?view=df

Wenn ich nun ganz einfach diesen WindowsMediaplayer in ein kleines Projekt einfüge, sehe ich eine Menge Procedure, Functionen usw., deren Bedeutung aber ziemlich unklar ist, auch viele Dateitypen... Leider sagt die Hilfe dazu nichts aus.
Ich habe mal alle Komponenten zusammengestellt. Kennt jemand eine Beschreibung zur Nutzung dieser Parameter ?

Delphi-Quellcode:

Windows Media Player Object Model Reference

[kwhk]

Danke Andreas, eine wirkliche Fundgrube ist das aber nicht.

[jaenicke]

Was fehlt dir denn z.B. konkret dort? Ich habe die Referenz schon ein paarmal genutzt, da war mir nicht aufgefallen, dass etwas fehlt. (Von dem was ich brauchte zumindest, auf den Rest habe ich nicht geschaut.)

[shmia]

Du wirst wahrscheinlich zur Automatisierungsschnittstelle des Media Player nicht allzuviel Informationen finden, weil:
* die Interfaces ständig weiterentwickelt werden und Infos schneller veralten als sie aufgeschrieben werden können
* viele Programmierer von der schlechten Qualität des Media Players abgeschreckt wurden
(zumindest früher waren Abstürze an der Tagesordnung; heute könnte die Qualität natürlich wesentlich besser sein)

[kwhk]

Ich brauche ein Programm, dem ich über die Kommandozeile den Dateinamen einer Videodatei übergebe. Dieses soll diese Datei abspielen, dabei in den Vollbildmodus schalten und dann, wenn das Abspielen zu Ende ist, sich selbst beenden.
Ich habe dazu mittels Probieren eine Lösung gefunden, die bei mir sowohl auf dem Desctop-PC mit WinXp und Win7prof-64 funktioniert, auch auf meinem Notebook mit Win7-ultimate-64.
So richtig gefällt mir das nicht, weil ich dazu die Status-Informationen in Form von deutschem WhiteString abfrage. Im Ausland würde das nicht funktionieren, weil da die Meldungen in englisch, französisch oder russisch kämen und meine Abfrage ins Leere laufen würde.
Ich muss zunächst abfragen, ob das Abspielen begonnen hat, weil sonst beim Umschalten in den Vollbildmodus ein Fehler kommt, das darf man nur machen, wenn abgespielt wird.
Die zweite Abfrage (über Status) ist die nach dem Ende des Abspielens, um das eigene Programm zu beenden.
Ich habe das alles in eine Timer-Routine gepackt, da wird aller Sekunden entsprechend abgefragt - das geht sicherlich viel eleganter.
Ich zeige nachfolgend mal meine Lösung...

Delphi-Quellcode:

unit HkMPlayer7u;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, ExtCtrls, StdCtrls, MPlayer, OleCtrls, WMPLib_TLB;

type
  TForm1 = class(TForm)
    WindowsMediaPlayer1: TWindowsMediaPlayer;
    Timer1: TTimer;
    procedure FormCreate(Sender: TObject);
    procedure Timer1Timer(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

Var
  qTimer1DL : Boolean = False;
  qPlayAnf  : Boolean = False;
  iTimerSek : Longint = 0;
  sStatus   : String;
  sDSN      : String;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Align := alClient;
  qTimer1DL := False;
  qPlayAnf := False;
  Timer1.Enabled := True;
end;

procedure TForm1.Timer1Timer(Sender: TObject);
begin
  if not qTimer1DL then
    Begin
      qTimer1DL := True;
      iTimerSek := 0;
      if ParamCount < 1 then
        Close;
      sDSN := ParamStr(1);

      WindowsMediaPlayer1.URL := sDSN;
    End;

  Inc(iTimerSek);

  sStatus := WindowsMediaPlayer1.status; // WideString
  Form1.Caption := 'HkMPlayer7   ' + sDSN + '   ' + sStatus;

  if not qPlayAnf then
    Begin
      if Length(sStatus) > 11 then
        Begin
          if Copy(sStatus,1,10) = 'Wiedergabe' then
            Begin
              qPlayAnf := True;
              WindowsMediaPlayer1.fullScreen := True;
            End
          else
            if iTimerSek > 30 then
              Close;
        End;
    End;

  if iTimerSek > 13 then
    Begin
      if sStatus = 'Beendet' then
        Begin
          Close;
        End;
    End;
end;

end.

Es muss property heissen.

Mein Tipp:

Lass den Media Player, Media Player sein, und steig stattdessen um auf das DSPack oder gar gleich auf reinen DirectX (DirectShow) Code.

Dazu hatte ich auch mal ein bsp. Programm geschrieben, wie so ein DX-Video/Audio Player aufgebaut wird. Den Rest kannst du mit Nachlesen erreichen ;)
