Delphi中MediaPlayer简单使用--播放视频

------------------

 

 

仅做简单的测试，只想看看怎么播放视频，不想弄这个，有兴趣的可以深入了解，谢谢！

要想更深入了解请参考：Delphi多媒体设计之TMediaPlayer组件（一） - pchmonster - 博客园  https://www.cnblogs.com/pchmonster/archive/2012/07/12/2588846.html

---------------------------Unit1 开始------------

unit Unit1;

interface

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

type
TForm1 = class(TForm)
MediaPlayer1: TMediaPlayer;
Animate1: TAnimate;
Button1: TButton;
Panel1: TPanel;
Timer1: TTimer;
Label1: TLabel;
procedure Button1Click(Sender: TObject);
procedure MediaPlayer1Click(Sender: TObject; Button: TMPBtnType;
var DoDefault: Boolean);
procedure Timer1Timer(Sender: TObject);
procedure FormCreate(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;

var
Form1: TForm1;

implementation
var
uDisplayRect:TRect;

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
//这个cool.avi在delphi7的安装目录下
MediaPlayer1.FileName:='C:\Program Files\Borland\Delphi7\Demos\CoolStuf\cool.avi' ;
end;

procedure TForm1.MediaPlayer1Click(Sender: TObject; Button: TMPBtnType;
var DoDefault: Boolean);
begin
if Button=btPlay then //case Button of btPlay:begin (代码) end; end;比较好
begin
MediaPlayer1.Open;//打开设备，还有对应的Close关闭设备
MediaPlayer1.DisplayRect:=uDisplayRect; //设置显示范围（本人设置的这个范围有点大了，视频失真）
MediaPlayer1.Play;//播放
end;
{case Button of
btPlay:
begin
MediaPlayer1.Open;//打开设备，还有对应的Close关闭设备
MediaPlayer1.DisplayRect:=uDisplayRect; //设置显示范围（本人设置的这个范围有点大了，视频失真）
MediaPlayer1.Play;//播放
end;
end; }
end;

procedure TForm1.Timer1Timer(Sender: TObject);
begin
Label1.Caption:=IntToStr(MediaPlayer1.Position);
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
uDisplayRect.Top:=10;
uDisplayRect.Left:=10;
uDisplayRect.Right:=500;
uDisplayRect.Bottom:=300;
MediaPlayer1.Display:=Panel1; //设置视频显示的地方（这里显示在panel上）
//Devicetype这个很重要，不要乱设置
end;

end.
