FFMPEG zwei Videos zusammenführen (Verkettung)

Question

Ich habe versucht, zwei mp4 Videos mit der gleichen Höhe und Breite zusammenzuführen, aber ein Fehler tritt auf. Der Code ist:

FFmpeg ffmpeg = FFmpeg.getInstance(EditVideoActivity.this); 
      String list = generateList(new String[]{ActualVideoFile.getAbsolutePath(), path}); 
      try { 
       ffmpeg.execute("ffmpeg -f concat -i " + list + " -c:v copy " + mergedVideo.getAbsolutePath(), new FFmpegExecuteResponseHandler() { 
        @Override 
        public void onStart() { 
         Log.e("Start", "Start"); 
        } 

        @Override 
        public void onFinish() { 
         Log.e("FINISHED", "finish"); 
        } 


        @Override 
        public void onSuccess(String message) { 
         Log.e("SUCCESS", message); 
        } 

        @Override 
        public void onProgress(String message) { 
         Log.e("PROGRESSSS", message); 
        } 

        @Override 
        public void onFailure(String message) { 
         Log.e("FAILURE", message); 
        } 


       }); 
      } catch (FFmpegCommandAlreadyRunningException e) { 
       e.printStackTrace(); 
       Log.e("FFMEG Exception", "" + e); 
      }

Ich verwende hiteshsondhi88 ‚s FFMPEG Bibliothek Jede Hilfe würde geschätzt. Dank

Statt der aktuellen:

ffmpeg.execute("ffmpeg -f concat -i " + list + " -c:v copy " + mergedVideo.getAbsolutePath(), new FFmpegExecuteResponseHandler() { 

Probieren Sie es wie folgt aus:

ffmpeg.execute("-f concat -i " + list + " -c:v copy " + mergedVideo.getAbsolutePath(), new FFmpegExecuteResponseHandler() {
