我在调试这些代码的时候出现许多关键字不能解析,可能是引入的包不正确,但我现在也不知道该怎么办?我jmf安装调试已经成功了
代码如下:
import javax.media.*;
import javax.media.renderer.*;
import java.awt.*;
import java.awt.image.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
import javax.imageio.plugins.jpeg.*;public class JMFVideo
{
// 利用这三个类分别获取摄像头驱动,和获取摄像头内的图像流,获取到的图像流是一个Swing的Component组件类 public static Player player = null;
private CaptureDeviceInfo di = null;
private MediaLocator ml = null;// 文档中提供的驱动写法,为何这么写我也不知:) String str1 = "vfw:Logitech USB Video Camera:0";
String str2 = "vfw:Microsoft WDM Image Capture (Win32):0";
di = CaptureDeviceManager.getDevice(str2);
ml = di.getLocator();
try
{
player = Manager.createRealizedPlayer(ml);
player.start();
Component comp;
if ((comp = player.getVisualComponent()) != null)
{
add(comp, BorderLayout.NORTH);
}
}
catch (Exception e)
{
e.printStackTrace();
}
//点击拍照,获取摄像头内的当前图像
private JButton capture;
private Buffer buf = null;
private BufferToImage btoi = null;
private ImagePanel imgpanel = null;
private Image img = null;
JComponent c = (JComponent) e.getSource();
if (c == capture)//如果按下的是拍照按钮
{
FrameGrabbingControl fgc =(FrameGrabbingControl) player.getControl("javax.media.control.FrameGrabbingControl");
buf = fgc.grabFrame(); // 获取当前祯并存入Buffer类
btoi = new BufferToImage((VideoFormat) buf.getFormat());
img = btoi.createImage(buf); // show the image
imgpanel.setImage(img);
}
//保存图像
BufferedImage bi = (BufferedImage) createImage(imgWidth, imgHeight);
Graphics2D g2 = bi.createGraphics();
g2.drawImage(img, null, null);
FileOutputStream out = null;
try
{
out = new FileOutputStream(s);
}
catch (java.io.FileNotFoundException io2)
{
System.out.println("File Not Found");
} JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(bi);
param.setQuality(1f, false);//不压缩图像
encoder.setJPEGEncodeParam(param);
try
{
encoder.encode(bi);
out.close();
}
catch (java.io.IOException io)
{
System.out.println("IOException");
}
public static void main(String[] args)
{
JMFVideo jmf=new JMFVideo();
}
}

程序的代码放的位置不对啊,怎么也要放在个函数里吧
