La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...) -

How to combine multiple Audio Files into single using ffmpeg_kit_flutter
17 septembre 2023, par sunil kalwaniI want to play multiple Audio files in a sequence to form a question for the users.

For that, I tried theAudioPlaypackage in the loop but they took some pause to play it in between which did not look good.

So as the alternative I want to combine audio files into a single file to play.

For that I have usedffmpeg_kit_flutterpackage, but this returns 1 which means error in merging the files.

List<string> assetAudioFiles = [
 'audio/S1B_1.mp3', // Replace with the URLs or local paths of your audio files
 'audio/L2_31.mp3',
 'audio/S1B_2.mp3',
 'audio/L1s20.mp3',
];

Future> copyAssetFilesToStorage() async {
 List<string> localFilePaths = [];

 for (String assetFile in assetAudioFiles) {
 String localFilePath = await copyAssetToFile(assetFile);
 localFilePaths.add(localFilePath);
 }

 return localFilePaths;
}
 
Future<string> copyAssetToFile(String assetFilePath) async {
 final ByteData data = await rootBundle.load(assetFilePath);
 final Directory tempDir = await getTemporaryDirectory();
 final File tempFile =
 File('${tempDir.path}/${assetFilePath.split('/').last}');
 await tempFile.writeAsBytes(data.buffer.asUint8List(), flush: true);
 return tempFile.path;
}
 
Future<void> combineAudio(List<string> audioFiles) async {
 Directory tempDir = await getTemporaryDirectory();
 String tempPath = tempDir.path;

 // Create a temporary output file path
 String combinedAudioPath = '$tempPath/output.mp3';

 // Prepare the FFmpeg command to concatenate audio files
 String inputFiles = audioFiles.join('|');

 String command =
 'ffmpeg -i "concat:$inputFiles" -acodec copy $combinedAudioPath';

 var cmd2 =
 "-i ${audioFiles[0]} -i ${audioFiles[1]} -i ${audioFiles[2]} -filter_complex [0:0][1:0][2:0]concat=n=3:v=0:a=1[out] -map [out] $combinedAudioPath";
 
 FFmpegKit.execute(cmd2).then((session) async {
 print('session $session');
 final returnCode = await session.getReturnCode();
 print('returnCode $returnCode');

 if (ReturnCode.isSuccess(returnCode)) {
 print('Audio files merged successfully $returnCode');
 // SUCCESS
 } else if (ReturnCode.isCancel(returnCode)) {
 print('isCancel $returnCode');
 // CANCEL
 } else {`enter code here`
 print('Error merging audio files: $returnCode');
 // audioPlayer.play(DeviceFileSource(outputFilePath));
 }
 });
}
 
void combineAndPlayAudio() async {
 List<string> localFilePaths = await copyAssetFilesToStorage();
 await combineAudio(localFilePaths); //localFilePaths

 // Now you can play the combined audio using an audio player or other methods.
}
</string></string></void></string></string></string>

So can you please let me know how to combine multiple audio files into single or a way to play multiple audio in sequence ?

How to use FFmpeg in android to edit video ? [closed]

package com.example.mytestapp.Activity;
 
 import android.content.Context;
 import android.os.AsyncTask;
 import android.os.Environment;
 import android.util.Log;
 import com.github.hiteshsondhi88.libffmpeg.ExecuteBinaryResponseHandler;
 import com.github.hiteshsondhi88.libffmpeg.FFmpeg;
 import com.github.hiteshsondhi88.libffmpeg.exceptions.FFmpegCommandAlreadyRunningException;
 
 public class MergeAudioVideoTask extends AsyncTask {
 private static final String TAG = MergeAudioVideoTask.class.getSimpleName();
 
 private Context context;
 private String videoFilePath;
 private final String audioFilePath;
 private final String outputFilePath;
 
 public MergeAudioVideoTask(String videoFilePath, String audioFilePath, String outputFilePath) {
 this.videoFilePath = videoFilePath;
 this.audioFilePath = audioFilePath;
 this.outputFilePath = outputFilePath;
 }
 
 // String inputAudioPath = "https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3";
 String outputVideoPath = Environment.getExternalStorageDirectory() + "/trimVideos" + "sangtest.mp4";
 
 // String[] command = {"-i", vpath, "-i", inputAudioPath, "-c:v", "copy", "-c:a", "aac", "-map", "0:v:0", "-map", "1:a:0", "-shortest", outputVideoPath};
 
 
 @Override
 protected Boolean doInBackground(Void... params) {
 String[] cmd = {"-i", videoFilePath, "-i", audioFilePath, "-shortest", outputVideoPath};
 try {
 FFmpeg.getInstance(context).execute(cmd, new ExecuteBinaryResponseHandler() {
 @Override
 public void onStart() {
 Log.e("Started", "yes");
 }
 
 @Override
 public void onProgress(String message) {
 // do nothing
 }
 
 @Override
 public void onFailure(String message) {
 Log.e("Failed ", "yes");
 }
 
 @Override
 public void onSuccess(String message) {
 Log.e("Success ", "yes");
 }
 
 @Override
 public void onFinish() {
 // do nothing
 }
 });
 } catch (FFmpegCommandAlreadyRunningException e) {
 e.printStackTrace();
 }
 
 return null;
 }
 
 @Override
 protected void onPostExecute(Boolean success) {
 if (success) {
 } else {
 }
 }
 
 }
