31 janvier 2010, parPréambule
Cet article n’a pas pour but de détailler les installations de ces logiciels mais plutôt de donner des informations sur leur configuration spécifique.
Avant toute chose SPIPMotion tout comme MediaSPIP est fait pour tourner sur des distributions Linux de type Debian ou dérivées (Ubuntu...). Les documentations de ce site se réfèrent donc à ces distributions. Il est également possible de l’utiliser sur d’autres distributions Linux mais aucune garantie de bon fonctionnement n’est possible.

How to merge two videos from Firebase Database and local file ? [closed]
2 avril 2020, par i iI need to merge two videos from a local file and Firebase Storage. How can I solve it ?
I can get the file from a local file but I couldn't get the video from Firebase Storage.



Part of my code :



if(secondlength >0){
 if (secondlength > secondinterval) {
 final File source = new File(files.get(1));
 // String filename = "https://firebasestorage.googleapis.com/v0/b/***.appspot.com/o/video_covers%2Fvideo_ornek.mp4?alt=media&token=10c3fa8a-4510-4984-8247-8036fffe18b3";
 // filesname.add(filename);
 // final File output = new File(Uri.parse(filename).getPath());
 String filename = String.format(Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + System.currentTimeMillis() + ".mp4");
 filesname.add(filename);
 final File output = new File(filename);
 startTrim(source, output, startsecond, startsecond + secondinterval);
 startsecond = startsecond + secondinterval + .7;
 secondlength = secondlength - secondinterval;
 Log.e("filename2 in 10", "" + filename);
 } else {
 final File source = new File(files.get(1));
 String filename = String.format(Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + System.currentTimeMillis() + ".mp4");
 filesname.add(filename);
 final File output = new File(filename);
 String DownloadUrl = "https://firebasestorage.googleapis.com/v0/b/*****.appspot.com/o/video_covers%2Fvideo_ornek.mp4?alt=media&token=10c3fa8a-4510-4984-8247-8036fffe18b3";
 DownloadManager.Request request1 = new DownloadManager.Request(Uri.parse(DownloadUrl));
 request1.setDescription("Sample Music File"); //appears the same in Notification bar while downloading
 request1.setTitle("File1.mp3");
 request1.setVisibleInDownloadsUi(false);

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
 request1.allowScanningByMediaScanner();
 request1.setNotificationVisibility(DownloadManager.Request.VISIBILITY_HIDDEN);
 }
 request1.setDestinationInExternalFilesDir(getApplicationContext(), "/File", "Question1.mp4");

 DownloadManager manager1 = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
 Objects.requireNonNull(manager1).enqueue(request1);
 if (DownloadManager.STATUS_SUCCESSFUL == 8) {
 Toast.makeText(AllVideoMerge.this, "success", Toast.LENGTH_SHORT).show();
 }

 startTrim(source, output, startsecond, startsecond + secondlength);
 startsecond = 0;
 secondlength = 0;


 Log.e("filename2", "" + filename);
 }
 }

 static Future<string> cutAudio(String path, double start, double end) async {
 final Directory dir = await getApplicationDocumentsDirectory();
 final outPath = "${dir.path}/output.mp3";
 double start = 1;
 double end = 5;

 try 
{
 await File(outPath).delete();
 } catch (e) {
 print("Delete Error");
 }

 var cmd =
 "-y -i \"$path\" -vn -ss $start -to $end -ar 16k -ac 2 -b:a 96k -acodec libmp3lame $outPath";

Concatenate audio files using ffmpeg
4 juin 2021, par user13962029I am trying to concatenate ac3 and aac using ffmpeg.


ffprobe of jpn_op.m4a :


Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'jpn_op.m4a':

I tried this :


ffmpeg -f concat -i concat_files.txt -c copy final.m4a -y


concat_files.txt contains :


file 'jpn_op.m4a'
file 'eng_nop.m4a'


ffprobe of final.m4a


Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'final.m4a':

But, there is silent in place of 2nd file in final.m4a
