culture vidéo Android en utilisant ffmpeg

Question

J'utilise https://github.com/WritingMinds/ffmpeg-android-java pour le détourage d'une vidéo à l'aide de cette commande:

execFFmpegCommand(" -i " + in + " -filter:v " + "crop=" + 240 + ":" + 120 + ":" + 100 + ":" + 100 + " -c:a copy " + out); 

où « dans » est inputfile et « out » est outputfile. Je suis passé par beaucoup de mêmes questions et je n'ai pas trouvé de solution requise pour cela. J'ai aussi essayé la commande suivante que je trouve en passant par la recherche:

execFFmpegCommand(" -i " + in + " -filter:v " + "crop=" + 240 + ":" + 120 + ":" + 100 + ":" + 100 + " -c:a copy " + out); 

La principale erreur que je reçois ici est: fichier de sortie # 0 ne contient aucun flux

private void execFFmpegCommand(final String command) { 
    try { 
     ffmpeg.execute(new String[]{command}, new ExecuteBinaryResponseHandler() { 
      @Override 
      public void onFailure(String s) { 
       Log.d(TAG, "FAILED with output : " + s); 
       progressDialog.dismiss(); 

      } 

      @Override 
      public void onSuccess(String s) { 
       Log.d(TAG, "SUCCESS with output : " + s); 
      } 

      @Override 
      public void onProgress(String s) { 
       Log.d(TAG, "Started command : ffmpeg " + command); 
       Log.d(TAG, "progress : " + s); 
      } 

      @Override 
      public void onStart() { 
       Log.d(TAG, "Started command : ffmpeg " + command); 
       progressDialog.show(); 
      } 

      @Override 
      public void onFinish() { 
       Log.d(TAG, "Finished command : ffmpeg " + command); 
       progressDialog.dismiss(); 

      } 
     }); 
    } catch (FFmpegCommandAlreadyRunningException e) { 
     // do nothing for now 
    } 
} 

Le LogCat est:

Answer 1

j'ai tout compris enfin, Le La commande doit être passée en tableau.

String[] cmd = {"-i", in, "-filter:v", "crop=" + 240 + ":" + 120 + ":" + 100 + ":" + 100, "-c:a", "copy", out}; 

    execFFmpegCommand(cmd);
