java 屏幕录制

昨天一朋友问我屏幕录制怎么搞。我只知不断的切图，切图后如何转成视频文件不清楚。

结果今天告诉我弄成了。下面的代码没有试验过，是我朋友给我，我共享出来，免去以后要用到处找。哈哈！！！

 

切屏的，这个代码应该到处都是.

这个就厉害了，好像是把图片弄成视频的样子。

package org;

import java.io.File;
import java.io.IOException;
import java.util.Arrays;
import java.util.Comparator;

import org.jim2mov.core.DefaultMovieInfoProvider;
import org.jim2mov.core.ImageProvider;
import org.jim2mov.core.Jim2Mov;
import org.jim2mov.core.MovieInfoProvider;
import org.jim2mov.utils.MovieUtils;

public class JpgToAvi {

	 public static void main(String[] args) throws Exception{
		 
	        //jpgs目录放置jpg图片,图片文件名为(1.jpg,2.jpg...)
	        final File[] jpgs = new File("C:\\record\\").listFiles();
	 
	        //对文件名进行排序(本示例假定文件名中的数字越小,生成视频的帧数越靠前)
	        Arrays.sort(jpgs,new Comparator<File>(){
		   public int compare(File file1, File file2) {
		       String numberName1 = file1.getName().replace(".jpg", "");
		       String numberName2 = file2.getName().replace(".jpg", "");
		       return new Integer(numberName1) - new Integer(numberName2);
		   }
	        });   
	 
	        DefaultMovieInfoProvider dmip = new DefaultMovieInfoProvider("dst.avi");
	        dmip.setFPS(1);			//设置每秒帧数
	         dmip.setNumberOfFrames(jpgs.length);	//总帧数
	         dmip.setMWidth(100);
	        dmip.setMHeight(200);     
	 
	        new Jim2Mov(new ImageProvider(){
		   public byte[] getImage(int frame) {
		       try {
	                   //设置压缩比
		           return MovieUtils.convertImageToJPEG((jpgs[frame]), 1.0f);  
	                } catch (IOException e) {
		           e.printStackTrace();
		       }
		       return null;
		   } 	
	        }, dmip, null).saveMovie(MovieInfoProvider.TYPE_AVI_MJPEG);
	    }    
}

 

可以看见，需要一个jar包啦，附件已上传。

 

我也没具体试过，朋友说可行。空了再试试。
