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.IOException;
import java.util.Arrays;
import java.util.Comparator;
import org.jim2mov.core.DefaultMovieInfoProvider;

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。
