東西/原料

netbeans ide 8.1
jmf2-1-1

方式/步調

1
新建一個java項目，項目標名字為javasxt.。
2
新建一個窗口（jframe),，窗口的類名Javasxt。
3
打開這個javasxt.java這個文件，在窗口中增添一個面板jpanel，這個面板是用來顯示攝像頭的畫面。
4
我的攝像頭是640*480的分辯率，所以把增添的面板的尺寸改當作寬度640，高度480，把窗口顯示位置設置為屏幕中心顯示。
5
把面板增添一個邊框。
6
把媒體框架（jmf）的庫函數包含在項目中。
7
在初始化函數中增添代碼：
引用攝像頭
CaptureDeviceManager.getDevice("vfw:Microsoft WDM Image Capture (Win32):0");
8
建立一個數據源:
MediaLocator med=new MediaLocator("vfw://0");
9
新建一個播放對象：
player=Manager.createRealizedPlayer(med);
10
把播放對象的顯示畫面的部件增添到用戶新建的面板中：
if(player.getVisualComponent()!=null){
jPanel1.add(player.getVisualComponent());
player.start();
}
11
運行項目窗口顯示攝像頭拍攝的畫面。
