Android FFmpeg Java Concat несколько файлов

Я использую вилку библиотеки Cordova-плагин-видео-редактор:Android FFmpeg Java Concat несколько файлов

https://github.com/jbavari/cordova-plugin-video-editor/pull/13

который использует библиотеку андроид-FFmpeg-Java здесь:

https://github.com/guardianproject/android-ffmpeg-java

Выездное коробчатого Cordova плагин например хорошо работает для кодирования одного видео, используя следующий код:

File tempFile = File.createTempFile("ffmpeg", null, appContext.getCacheDir()); 
FfmpegController ffmpegController = new FfmpegController(appContext, tempFile); 

TranscodeCallback tcCallback = new TranscodeCallback(); 

Clip clipIn = new Clip(videoSrcPath); 
Clip clipOut = new Clip(outputFilePath); 
clipOut.videoCodec = "libx264"; 
clipOut.videoFps = "24"; // tailor this to your needs 
clipOut.videoBitrate = 512; // 512 kbps - tailor this to your needs 
clipOut.audioChannels = 1; 
clipOut.width = outputWidth; 
clipOut.height = outputHeight; 
clipOut.duration = videoDuration; 
ffmpegController.processVideo(clipIn, clipOut, true, tcCallback);

Это вызывает андроид-FFmpeg-Java код здесь:

https://github.com/guardianproject/android-ffmpeg-java/blob/master/src/org/ffmpeg/android/FfmpegController.java#L225

Они имеют несколько пример тестового CONCAT файл здесь:

https://github.com/guardianproject/android-ffmpeg-java/blob/master/src/org/ffmpeg/android/test/ConcatTest.java#L16

Так что я модифицировал Cordova плагин кода в соответствии с примером:

ArrayList<Clip> listVideos = new ArrayList<Clip>(); 

Clip clip = new Clip(); 
clip.path = new File(videoSrcPath).getCanonicalPath(); 
ffmpegController.getInfo(clip); 
clip.duration = 5; 
listVideos.add(clip); 

Clip clip2 = new Clip(); 
clip2.path = new File(videoSrcPath2).getCanonicalPath(); 
ffmpegController.getInfo(clip2); 
clip2.duration = 5; 
listVideos.add(clip2); 

Clip clipOut = new Clip(); 
clipOut.path = new File(outputFilePath).getCanonicalPath(); 
ffmpegController.concatAndTrimFilesMP4Stream(listVideos, clipOut, false, false, new ShellUtils.ShellCallback() { 
    @Override 
    public void shellOut(String shellLine) { 
     System.out.println("fc>" + shellLine); 
    } 
    @Override 
    public void processComplete(int exitValue) { 
     if (exitValue < 0) 
      System.err.println("concat non-zero exit: " + exitValue); 
    } 
});

Однако при запуске я получаю сообщение об ошибке:

Я не знаю, почему он говорит, что "не каталог? Разумеется, это действительно так, потому что файлы создаются на предыдущем шаге?
