对不起,当我标记ffmpeg时,因为我不能标记MP4Box.But,所以我也通过javacode执行了ffmpeg。我在How to execute cmd commands via Java读书,但找不到我的问题。
我在cmd中测试了命令,很好:
MP4Box -dash 10000 -dash-profile活动段-名称输出- seg -rap -bs-没有交换input.mp4
但是,当我通过java代码执行cmd时,我得到了错误:
错误-只有一个输入文件作为参数,请检查使用情况。
下面是我的代码,有什么问题吗?
package com.uit.reformatvideo;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.logging.Logger;
public class ExecuteComandToFormatVideo {
public final static String LINK_MP4BOX = "C:/MP4Box/Tools/MP4Box.exe";
public final static String CREATE_MPD_ECLIPSE = "mp4box -dash 10000 -frag 1000 -rap -bs-switching no";
public final static String CREATE_MPD_IE = "MP4Box -dash 10000 -dash-profile live -segment-name output-seg -rap -bs-switching no";
private static final Logger log = Logger.getLogger(ExecuteComandToFormatVideo.class.getName());
public static void main(String[] args) throws IOException, InterruptedException {
String s = null;
try {
// run the Unix "ps -ef" command
// using the Runtime exec method:
String lsCmd[] = new String [2];
lsCmd[0] = LINK_MP4BOX;
lsCmd[1] = "MP4Box -dash 10000 -dash-profile live -segment-name output-seg -rap -bs-switching no input.mp4";
Process p = Runtime.getRuntime().exec(lsCmd);
p.waitFor();
BufferedReader stdInput = new BufferedReader(new
InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new
InputStreamReader(p.getErrorStream()));
// read the output from the command
System.out.println("Here is the standard output of the command:\n");
while ((s = stdInput.readLine()) != null) {
System.out.println(s);
}
// read any errors from the attempted command
System.out.println("Here is the standard error of the command (if any):\n");
while ((s = stdError.readLine()) != null) {
System.out.println(s);
}
System.exit(0);
}
catch (IOException e) {
System.out.println("exception happened - here's what I know: ");
e.printStackTrace();
System.exit(-1);
}
}
}这里被发布了:
下面是命令的标准输出: 下面是命令的标准(如果有的话):Error -只有一个输入文件作为参数,请检查使用情况

对不起,因为我的英语很差。我创建了一个bat文件,其中包括命令,比如CMD,然后我使用Runtime.getRuntime().exec(url+name+".bat");来执行bat文件。这是我的解决方案。我的蝙蝠档案:
cd C:/MP4Box/Tools/
MP4Box
MP4Box -dash 10000 -dash-profile live -segment-name output-seg -rap -bs-switching no "C:\Users\ducth\Desktop\New folder (2)\SharingVideo\src\main\webapp\resources\video\output.mp4"https://stackoverflow.com/questions/33461300
