Comment rogner la vidéo avec la bibliothèque ffmpeg dans Android?

Pour rogner la vidéo dans l'application Android J'utilise ffmpeg bibliothèqueComment rogner la vidéo avec la bibliothèque ffmpeg dans Android?

dans la example j'ai trouvé pour la culture vidéo la commande suivante:

ffmpeg -i in.mp4 -filter: v « culture = out_w: out_h: x: y » out.mp4

I créé un tableau de chaînes:

String [] = {cmd "ffmpeg", "-i", originalVid eoPath, "-vf", "\" crop = "+ imageWidth +": "+ imageHauteur +": "+ xCoordinate +": "+ yCoordinate +" \ "", "-c: a", "copie", croppedVideoPath};

Et je passe ce tableau à la méthode execute():

try { 
      ffmpeg = FFmpeg.getInstance(getContext()); 
      ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() { 

       @Override 
       public void onStart() { 
        Log.i(TAG, "onStart: Crop Video started"); 
       } 

       @Override 
       public void onProgress(String message) { 
        Log.i(TAG, "onProgress: " + message); 
       } 

       @Override 
       public void onFailure(String message) { 
        Log.i(TAG, "onFailure: " + message); 
       } 

       @Override 
       public void onSuccess(String message) { 
        Log.i(TAG, "onSuccess: " + message); 
       } 

       @Override 
       public void onFinish() { 
        Log.i(TAG, "onFinish: Video cropping finished"); 
       } 
      }); 
     } catch (FFmpegCommandAlreadyRunningException e) { 
      // Handle if FFmpeg is already running 
      Log.i(TAG, "doInBackground: Exception + Device is not supported"); 
     }

Mais lorsque je supprime ffmpeg du tableau de commande

Chaîne [] cmd = {"-i", cheminVideoVideo, "-vf", "\" crop = "+ imageWidth +": "+ imageHauteur": "+ xC oordinate + ":" + yCoordinate + "\" "," -c: a "," copier ", croppedVideoPath};

Après execute, le résultat est:
