将视频转换为字节 [英] convert video to byte

问题描述

想在Java中将视频内容转换为字节吗，有什么机构可以帮助我做到这一点?

want to convert the content of video to byte in java could any body help me to do that?

推荐答案

尝试一下:

Try this:

package Practice;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;


public class Temp {

public static void main(String[] args)
{
   File file = new File("c:/EventItemBroker.java");

   byte[] b = new byte[(int) file.length()];
try
 {
   FileInputStream fileInputStream = new FileInputStream(file);
   fileInputStream.read(b);
   for (int i = 0; i < b.length; i++) {
     System.out.print((char)b[i]);
   }
 } catch (FileNotFoundException e) {
  System.out.println("File Not Found.");
  e.printStackTrace();
}
catch (IOException e1)
{
  System.out.println("Error Reading The File.");
  e1.printStackTrace();
}
}
}

还可以看看:
ByteArray [ FileInputStream [文件(URI) [ ^ ]


另类:

Also have look:
ByteArray[^]
FileInputStream[^]
File(URI)[^]


Alternative:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
FileInputStream fis = new FileInputStream(new File(yourUri));

byte[] buf = new byte[1024];
int n;
while (-1 != (n = fis.read(buf)))
    baos.write(buf, 0, n);

byte[] videoBytes = baos.toByteArray();
