Fluent ffmpeg not running synchronously
14 mai 2022, par sciencaholicI am writing a program where I need to process a video multiple times using ffmpeg. The ffmpeg codes (below) are inside a 'then' statement of a promise.



ffmpeg(path)
 .size('640x?')
 .aspect('1:1')
 .autopad('#682BAB')
 .saveToFile(`${userDirPath}/11-${userFileName}`)
 .on('end', () => {
 ffmpeg()
 .input('test-11-start.mp4')
 .mergeAdd(`${userDirPath}/11-${userFileName}`)
 .mergeAdd('test-11-end.mp4')
 .mergeToFile(`${userDirPath}/11-final-${userFileName}`, 'temp/')
 .on('end', () => console.log('FFmpeg done!'));
 });



There is another ffmpeg function after this (same, but with a different aspect ratio) and then, a 'then' statement with some other functions.



The problem is that this ffmpeg function runs asynchronously, and the next statements (which use the resulting file of ffmpeg func) are executed before it finishes executing and so I want it to run synchronously. I've tried async await (below) but it still runs asynchronously. What is wrong with code ?



async function ffmpegMerge() {
 try {
 await ffmpeg(path)
 .size('640x?')
 .aspect('1:1')
 .autopad('#682BAB')
 .saveToFile(`${userDirPath}/11-${userFileName}`)
 .on('end', () => {
 ffmpeg()
 .input(`test-11-start.mp4`)
 .mergeAdd(`${userDirPath}/11-${userFileName}`)
 .mergeAdd(`test-11-end.mp4`)
 .mergeToFile(`${userDirPath}/11-final-${userFileName}.mp4`, 'temp/')
 .on('end', () => console.log('FFmpeg done!'));
 })
 }
 catch (err) {
 return Promise.reject(new Error(err));
 }
}

merge multiple ffmpeg commands into one line to make the whole process faster
8 septembre 2020, par user1hjgjhgjhggjhgI want to merge multiple commands into one so that whole processing time would be fastest. What I am doing so far is


- 

-
A video file is uploaded from a webform and and server upload into a temp directory.


if (move_uploaded_file($_FILES[$param]['tmp_name'], $filePath)) {


 return $filePath;
 }


-
add black borders around the video(through ffmpeg command) - video uploads again to a directory


$command_new = "ffmpeg -i $filePath -vf 'scale=720:1280:force_original_aspect_ratio=decrease,pad=720:1280:(ow-iw)/2:(oh-ih)/2,setsar=1' $video_file";
 exec($command_new);


-
optimizing the video(ffmpeg command) - video uploads again to a directory


$cmd_new = "ffmpeg -i $video_file -c:v libx264 -crf 28 $optimizeResultFile";


-
merging the uploaded file with the existing video file present in the database into one and uploading that file into directory(through ffmpeg command)


$command_new = "ffmpeg -i $optimizeResultFile -i $second_video_path -filter_complex '[0:v]pad=iw*2:ih[int];[int][1:v]overlay=W/2:0[vid]' -map [vid] -c:v libx264 -crf 23 -preset veryfast $videomerge";


-
//add custom sound in that final merged video


$cmd_new = "ffmpeg -i $videomerge -i $audio -c:v copy -c:a aac -shortest -map 0:v:0 -map 1:a:0 $with_new_audio";














Is it possible to do all at one command and not in multiple commands. This process takes 1 min to upload a final file. want to make it faster

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();
