De l’upload à la vidéo finale [version standalone]
31 janvier 2010, parLe chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.

ffmpeg - produces corrupted file
1er mai 2015, par pomegranateI have a mp4 file that I need to convert to avi to run a matlab script on. This script strips the file of any audio, so then I have to merge it back with the audio and then reconvert the avi to mp4. I’m doing this in a number of steps, and am uncertain at which point I’m screwing the commands up... basically, the final mp4 file I create it corrupted and cannot be played in quicktime (though it does work in VLC).
Here are the steps I am taking :
1) ffmpeg -i original.mp4 -acodec copy -vcodec copy original.avi
This converts mp4 to avi.
2) ffmpeg -i original.mp4 -acodec copy original.aac
This gets the audio from the mp4.
3) Run matlab script, which produces new-no-sound.avi
4) ffmpeg -i new-no-sound.avi -i original.aac -c:v copy -c:a aac -strict experimental new-with-sound.avi
This merges the old audio with the new avi file
5) ffmpeg -i new-no-sound.avi -c:v libx264 -crf 19 -preset slow -c:a libfaac -b:a 192k -ac 2 final-version.mp4
This converts the new merged file to mp4.Here’s the ffmpeg -i from the original.mp4 :

Call bash function in Java
16 mai 2023, par ilie alexandruI have been using Java with bash in order to make some things easier, some examples :


From the main class to call a subclass in order to use bash commands :


Main classs :


//Checking if the server already has the user or not
 CheckUser checkUser = new CheckUser();
 int checuser= checkUser.CheckUserMethod(user);
 if( 1 != checuser) { // Yoda notation

 //Making the directory for the user
 File userDirectory = new File(this.directory);
 userDirectory.mkdir();
 }


The class that will call the ".sh" file :


public class CheckUser {

protected int CheckUserMethod(String user){
 try {

 Process p = Runtime.getRuntime().exec(new String[]{"bash", "-c", "cd ~/Final-Year-Spring/src/main/java/query && ./checkuser.sh " + user});
 BufferedReader srdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
 String s =srdInput.readLine();
 if(s==null){
 return 0;
 }else {
 return Integer.parseInt(s);
 }
 }catch (Exception e){
 throw new RuntimeException(e);
 }
}




The bash file :


#!/bin/bash

# shellcheck disable=SC2237
if ! [ -z "$1" ]
then
 cd ~/Final-Year-Spring/maps/ && find "$1" -maxdepth 0 -type d -printf 1
fi


Now you have a context.


I am trying to call a bash file that will execute a ffmpeg command. For instance, the same command when I am using the terminal :


ffmpeg -ss 00:00:00.75 -to 00:00:00.93 -i ~/IdeaProjects/Final-Year-Spring/datassets/Alex/check/5535415699068794046/00009.mp4 -ss 00:00:01.71 -to 00:00:01.82 -i ~/IdeaProjects/Final-Year-Spring/datassets/Alex/check/5535415699068794046/00009.mp4 ~/IdeaProjects/Final-Year-Spring/maps/output.mp4S


Also a screenshot with the command in the cli :




The result of the cli command :




Now I am trying to do the same thing for multiple videos using Java and Bash.


The class that will create the input and the time :


public String CreateNewVideoMethod()


ArrayList<string> arrayList = new ArrayList<>();

MainSearch mainSearch = new MainSearch(this.array, this.search);
HashMap>>> map = new HashMap<>();
 map = mainSearch.SearchInVideous();


HashMap>> file = new HashMap<>();
file=map.get(this.array.get(1));

file.forEach((k,v)->{
 StringBuilder stringBuilder = new StringBuilder(this.defaultpth);
 stringBuilder.append("/")
 .append(this.array.get(0))
 .append("/")
 .append(this.array.get(1))
 .append("/")
 .append(k)
 .append("/")
 .append("InfoVideo.txt");

 GetVideoPath getVideoPath = new GetVideoPath();
 String videoPath = getVideoPath.GetVideoPathMethod(stringBuilder);

 v.forEach((k1,v1)->{ // iterate though the words
 v1.forEach((k2,v2)->{ // iterate though the times

 String doubleAsStringForKey = String.valueOf(k2);
 String[] arr = doubleAsStringForKey.split("\\.");

 String doubleASStringForValue = String.valueOf(v2);
 String[] arr2 = doubleASStringForValue.split("\\.");

 if(k2>10){

 StringBuilder stringBuilder1 = new StringBuilder();
 stringBuilder1.append(" -ss ")
 .append("00:00:")
 .append(arr[0])
 .append(".")
 .append(arr[1])
 .append(" -to ")
 .append(" 00:00:")
 .append(arr2[0])
 .append(".")
 .append(arr2[1])
 .append(" -i ")
 .append(videoPath);
 arrayList.add(String.valueOf(stringBuilder1));
 }
 else{

 StringBuilder stringBuilder1 = new StringBuilder();
 stringBuilder1.append(" -ss ")
 .append("00:00:0")
 .append(arr[0])
 .append(".")
 .append(arr[1])
 .append(" -to ")
 .append("00:00:0")
 .append(arr2[0])
 .append(".")
 .append(arr2[1])
 .append(" -i ")
 .append(videoPath);
 arrayList.add(String.valueOf(stringBuilder1));
 }

 });
 });

});

BashFIleForCreatingNewVideo bashFIleForCreatingNewVideo = new BashFIleForCreatingNewVideo();
bashFIleForCreatingNewVideo.BashFileForCreatingNewVideo(arrayList);
</string>

The class that must call the ".sh" file :


public class BashFIleForCreatingNewVideo {

 protected String BashFileForCreatingNewVideo(ArrayList<string> arrayList){
 try {

 StringBuilder stringBuilder = new StringBuilder();

 for(String str : arrayList){
 stringBuilder.append(str);
 }
 Process p = Runtime.getRuntime().exec(new String[]{"bash", "-c", "cd ~/IdeaProjects/Final-Year-Spring/src/main/java/com/FinalYearProjectServer/Get_Requests/CreateNewVideo && ./createNewVideo.sh ", String.valueOf(stringBuilder), String.valueOf(arrayList.size()-1), "./maps/outputstream.mp4"});
 BufferedReader srdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
 String s =srdInput.readLine();

 if(s==null){
 return "Error";
 }else {
 System.out.println(s);
 return s;
 }

 } catch (IOException e) {
 throw new RuntimeException(e);
 }

 }
}
</string>

The script file :


#!/bin/bash

arr=( "$@" )

echo "${arr[*]}"

ffmpeg "${arr[0]}" -filter_complex concat=n="${arr[1]}":v=1:a=1 "${arr[2]}"


What is passed to the script, small exaple, this is a string :


-ss 00:00:00.75 -to 00:00:00.93 -i ~/IdeaProjects/Final-Year-Spring/datassets/Alex/check/5535415699068794046/00009.mp4 -ss 00:00:01.71 -to 00:00:01.82 -i ~/IdeaProjects/Final-Year-Spring/datassets/Alex/check/5535415699068794046/00009.mp4 -ss 00:00:00.09 -to 00:00:00.34 -i ~/IdeaProjects/Final-Year-Spring/datassets/Alex/check/5535415699068794046/00027.mp4


The next parameter is the number of videos that must concatenate and the last parameter is where the output must be.


My problem is the Bash file is not executing even the echo command or doing something. Do you have any suggestion, because I thing is about the way of how I am passing the array to the Bash file.


Ok so I am trying to use ProcessBuilder :


String[] command = {"bash","ffmpeg", String.valueOf(stringBuilder), "-filter_complex concat=n="+String.valueOf(arrayList.size()-1)+":v=1:a=1", "~/IdeaProjects/Final-Year-Spring/maps/output1.mp4"};
 ProcessBuilder p = new ProcessBuilder(command);
 Process p2 = p.start();
 BufferedReader srdInput;
 srdInput = new BufferedReader(new InputStreamReader(p2.getInputStream()));
 String s =srdInput.readLine();
