JMF捕获技术（视频）

最近由于项目要求要获取视频.

在网上找了些代码又对其修改.

这个是视频类.

package com.cayden.video;import java.awt.Component;import java.awt.Frame;import java.awt.Panel;import java.io.IOException;import javax.media.CaptureDeviceInfo;import javax.media.CaptureDeviceManager;import javax.media.ControllerEvent;import javax.media.ControllerListener;import javax.media.Manager;import javax.media.MediaLocator;import javax.media.NoPlayerException;import javax.media.Player;import javax.media.PrefetchCompleteEvent;import javax.media.RealizeCompleteEvent;import javax.media.bean.playerbean.MediaPlayer;import javax.swing.JFrame;class CaptureVideo extends JFrame implements ControllerListener { private CaptureDeviceInfo infor ;private MediaLocator mediaLocator ; private String url = "vfw:Microsoft WDM Image Capture (Win32):0"; private Component com; private Panel panel ; Player player;public CaptureVideo() { infor = CaptureDeviceManager.getDevice(url); mediaLocator = infor.getLocator(); } public void player() { try { player =Manager.createPlayer(mediaLocator);//利用mediaLocator创建Player player.addControllerListener(this); player.realize(); } catch (NoPlayerException e) { // TODO 自动生成 catch 块 e.printStackTrace(); } catch (IOException e) { // TODO 自动生成 catch 块 e.printStackTrace();} } public void createComponent() { setTitle("视频信号"); setBounds(100,100,640,480); panel = new Panel(); if((com = player.getVisualComponent()) != null) { panel.add(com); } add(panel); setVisible(true); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } public synchronized void controllerUpdate(ControllerEvent arg0) { // TODO 自动生成方法存根 if(arg0 instanceof RealizeCompleteEvent) { System.out.println("realized"); createComponent(); //将播放器添加到Panel上 player.prefetch(); } if(arg0 instanceof PrefetchCompleteEvent) { player.start(); System.out.println("prefetched"); } } }

下面的是测试类

package com.cayden.video;public class Test { public static void main(String[] args) {CaptureVideo video = new CaptureVideo(); video.player();}}
