java中运行bat文件怎么才能不产生dos窗口，不带闪的

java中运行一个bat文件如下：

@echo off
C:/temp/ffmpeg.exe -i rtsp://218.204.223.237:554/live/1/66251FC11353191F/e7ooqwcfbqjoo80j.sdp -qscale 0 -t 00:00:30 -y C:/temp/%1 >C:/temp/log.txt 2>&1
exit
java中调用：
String strcmd = "cmd /c start C:\\temp\\ffmpeg.bat " + savePath;
Runtime.getRuntime().exec(strcmd);
怎样才能在运行中不产生Dos窗口

Answer 1

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.SequenceInputStream;
public class Processing {
    public static void main(String[] args) throws InterruptedException {
        try {
            Process process = Runtime.getRuntime().exec("cmd");
            SequenceInputStream sis = new SequenceInputStream(process.getInputStream(), process.getErrorStream());
            InputStreamReader isr = new InputStreamReader(sis, "GBK");
            BufferedReader br = new BufferedReader(isr);
            // next command
            OutputStreamWriter osw = new OutputStreamWriter(process.getOutputStream());
            BufferedWriter bw = new BufferedWriter(osw);
            bw.write("cd /d d:/我的文档/桌面");
            bw.newLine();
            bw.write("ffmpeg -help");
            bw.newLine();
            bw.flush();
            bw.close();
            osw.close();
            // read
            String line = null;
            while (null != (line = br.readLine())) {
                System.out.println(line);
            }
            process.destroy();
            br.close();
            isr.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

解决不弹框只需要“start”后面加一个参数“/b”就行：
Runtime.getRuntime().exec("cmd.exe /C start /b D:\\test.bat");

isr.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}

加上/b就行了
String strcmd = "cmd /c start /b C:\\temp\\ffmpeg.bat " + savePath;
