Android обрезать видео с помощью FFmpeg

Question

Я использую https://github.com/WritingMinds/ffmpeg-android-java для обрезки видео с помощью этой команды:

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

, где «в» является входной_файл и «из» является выходной_файл.

Я прошел через множество одинаковых вопросов и не нашел нужное решение для этого. Я также попробовал следующую команду, которую я нашел, проходящую через поиск:

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

Основная ошибка, которую я получаю здесь есть: выходной файл #-не содержит поток

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 
    } 
} 

LogCat является:

Answer 1

Я понял это, наконец, команда должна быть передана как массив.

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

    execFFmpegCommand(cmd);
