java.io.IOException: exec() Çalışırken hata oluştu Çalışma Dizini: null Ortam: null

Question

Uygulamada WritingMinds/ffmpeg-android-java kullanıyorum. İstisna ise: burada

kodum

loadFFmpeg(); 
String cmd="ffmpeg -i /storage/emulated/0/media/audio/a.mp3 -i /storage/emulated/0/recording.3gp -filter_complex \"[0:a][1:a]amerge=inputs=2[aout]\" -map \"[aout]\" " + outputFile; 
executeFFmpeg(cmd.split(" ")); 

ve

private void loadFFmpeg() { 
    FFmpeg ffmpeg = FFmpeg.getInstance(MainActivity.this.getApplicationContext()); 
    try { 
     ffmpeg.loadBinary(new LoadBinaryResponseHandler() { 

      @Override 
      public void onStart() {} 

      @Override 
      public void onFailure() {} 

      @Override 
      public void onSuccess() {} 

      @Override 
      public void onFinish() {} 
     }); 
    } catch (FFmpegNotSupportedException e) { 
     // Handle if FFmpeg is not supported by device 
    } 
} 

private void executeFFmpeg(String[] cmd) 
{ 
    /*String workFolder = getApplicationContext().getFilesDir() + "/ffmpeg"; 
    String environment = Environment.getExternalStorageDirectory().getAbsolutePath(); 
    Map<String, String> map = new HashMap<String, String>(); 
    map.put("Working Directory", workFolder); 
    map.put("Environment",environment);*/ 
    FFmpeg ffmpeg = FFmpeg.getInstance(MainActivity.this.getApplicationContext()); 
    try { 
     // to execute "ffmpeg -version" command you just need to pass "-version" 
     ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() { 

      @Override 
      public void onStart() {} 

      @Override 
      public void onProgress(String message) {} 

      @Override 
      public void onFailure(String message) {} 

      @Override 
      public void onSuccess(String message) {} 

      @Override 
      public void onFinish() { 
       stop.setEnabled(false); 
       play.setEnabled(true); 
      } 
     }); 
    } catch (FFmpegCommandAlreadyRunningException e) { 
     // Handle if FFmpeg is already running 
    } 
} 

ama aşağıdaki alıyorum hata
