JMF应用篇 之 从摄像头捕获视频

http://blog.csdn.net/sunny3106/archive/2007/05/06/1598143.aspx

Quick Start

安装jmf-2_1_1e-windows-i586.exe，可以在我的第一个JMF教程里面下载。然后运行JMF Registry，选择Capture Devices里面的Detect capture Devices，得到以下结果：

eclipse里面新建一个Java Project，名字叫做Oops_JMFCam。项目添加引用jmf.jar，在安装目录下面的lib找到。

在项目的src目录下面添加文件CaptureVideo.java。

 

import  javax.media. * ;

import  java.io. * ;

import  java.awt. * ;

classCaptureVideoextendsFrameimplementsControllerListener

{

    privateCaptureDeviceInfo infor;

    privateMediaLocator mediaLocator;

    privateString url  =   " vfw:Microsoft WDM Image Capture (Win32):0 " ;

    privateComponent com;

    privatePanel panel;

    Player player;

     public  CaptureVideo()

    {

        infor  =  CaptureDeviceManager.getDevice(url);

        mediaLocator  =  infor.getLocator();

    }

    publicvoid play()

    {

         try

        {

            player  =  Manager.createPlayer(mediaLocator); //  利用mediaLocator创建Player

            player.addControllerListener( this );

            player.realize();

             //  System.out.println("infor:"+infor);

             //  System.out.println("mediaLocator:"+mediaLocator);

        }

         catch  (NoPlayerException e)

        {

             //  TODO 自动生成 catch 块

            e.printStackTrace();

        }

         catch  (IOException e)

        {

             //  TODO 自动生成 catch 块

            e.printStackTrace();

        }

    }

    publicvoid createComponent()

    {

        setTitle( " 视频信号 " );

         //  addWindowListener(new WinClose());

        setBounds( 100 ,  100 ,  200 ,  200 );

        panel  =  newPanel();

         if  ((com  =  player.getVisualComponent())  !=   null )

        {

            panel.add(com);

        }

        add(panel);

        setVisible( true );

    }

    publicsynchronizedvoid controllerUpdate(ControllerEvent arg0)

    {

         //  TODO 自动生成方法存根

         if  (arg0 instanceofRealizeCompleteEvent)

        {

            System.out.println( " realized " );

            createComponent();  //  将播放器添加到Panel上

            player.prefetch();

        }

         if  (arg0 instanceofPrefetchCompleteEvent)

        {

            player.start();

            System.out.println( " prefetched " );

        }

    }

    publicstaticvoid main(String[] arg0)

    {

        CaptureVideo video  =  newCaptureVideo();

        video.play();

    }

}

 

Run as Java Application，得到结果
