MediaSPIP en mode privé (Intranet)
17 septembre 2013, parÀ partir de la version 0.3, un canal de MediaSPIP peut devenir privé, bloqué à toute personne non identifiée grâce au plugin "Intranet/extranet".
Le plugin Intranet/extranet, lorsqu’il est activé, permet de bloquer l’accès au canal à tout visiteur non identifié, l’empêchant d’accéder au contenu en le redirigeant systématiquement vers le formulaire d’identification.

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);
 }
 }
