JAVA for Video File

Kkus

Dear All Community Member,

I want to asking the question is that when i write a program in java to split video file like(.mp4,.wmv,.flv,etc.) after split one part is running video but rest part not shown anything ..... and after merging file it runs complete videos.... how it is possible...

my code is here.....

import java.io.*;

public class SplitVideoFile {

    public static void main(String[] args) {

        try {

            File file = new File("F:/kri.jpg");//File read from Source folder to Split.

            if (file.exists()) {

            String videoFileName = file.getName().substring(0, file.getName().lastIndexOf(".")); // Name of the videoFile without extension

            File splitFile = new File("F:"+ videoFileName);//Destination folder to save.

            if (!splitFile.exists()) {

                splitFile.mkdirs();

                System.out.println("Directory Created -> "+ splitFile.getAbsolutePath());

            }

            int i = 01;// Files count starts from 1

            InputStream inputStream = new FileInputStream(file);

            String videoFile = splitFile.getAbsolutePath() +"/"+ String.format("%02d", i) +"_"+ file.getName();// Location to save the files which are Split from the original file.

            OutputStream outputStream = new FileOutputStream(videoFile);

            System.out.println("File Created Location: "+ videoFile);

            int totalPartsToSplit = 2;// Total files to split.

            int splitSize = inputStream.available() / totalPartsToSplit;

            int streamSize = 0;

            int read = 0;

            while ((read = inputStream.read()) != -1) {

                if (splitSize == streamSize) {

                    if (i != totalPartsToSplit) {

                        i++;

                        String fileCount = String.format("%02d", i); // output will be 1 is 01, 2 is 02

                        videoFile = splitFile.getAbsolutePath() +"/"+ fileCount +"_"+ file.getName();

                        outputStream = new FileOutputStream(videoFile);

                        System.out.println("File Created Location: "+ videoFile);

                        streamSize = 0;

                    }

                }

                outputStream.write(read);

                streamSize++;

            }

            inputStream.close();

            outputStream.close();

            System.out.println("Total files Split ->"+ totalPartsToSplit);

        } else {

            System.err.println(file.getAbsolutePath() +" File Not Found.");

        }

    } catch (Exception e) {

        e.printStackTrace();

    }

}

}

Your question has nothing to do with Java.

The point is that any of the file formats you mentionned has an internal structure. Part of this structure is that at the beginning the file contains some information about how it is organized. This information is needed by the player to convert the files data into  pictures and sound.

If you just split the file at random indexes only the first part contains this information.
