Androidでffmpegコマンドを実行すると、「 '-map 0：v：0 -map 1：a：0'」の適切な出力形式を見つけることができません。

Question

私はこのコマンドを使用して、新しいオーディオを持っている。ここFILE1 FILE2は私のaudio.mp3と出力がoutput.mp4だろうで、私のvideo.mp4です：

以下

complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-c", "copy", " -map 0:v:0 -map 1:a:0", rootPath + "/output.mp4"}; 

は私のコードです：

以下

private void changeAudioofVideo(String selectedUri, String videoPath) { 

    String[] complexCommand; 


    File f = new File("/storage/emulated/0"); 
    if (!f.getParentFile().exists()) 
     f.getParentFile().mkdirs(); 
    if (!f.exists()) 
     try { 
      f.createNewFile(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 

    file1 = new File(videoPath); 
    if (file1.exists()) { 
     Log.d("yes", "File 1 exists"); 
    } else { 
     Log.d("no", "File 1 not exists"); 
    } 

    file2 = new File(selectedUri); 
    if (file2.exists()) { 
     Log.d("yes", "File 1 exists"); 
    } else { 
     Log.d("no", "File 1 not exists"); 
    } 

    String rootPath = f.getPath(); 

    complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-c", "copy", " -map 0:v:0 -map 1:a:0", rootPath + "/output.mp4"}; 

    FFmpeg ffmpeg = FFmpeg.getInstance(this); 

    try { 
     //Load the binary 
     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 
     Toast.makeText(getApplicationContext(), "Not Supported by Device", Toast.LENGTH_LONG).show(); 
    } 

    try { 

     final String finalRootPath = rootPath; 
     ffmpeg.execute(complexCommand, new FFmpegExecuteResponseHandler() { 
      @Override 
      public void onSuccess(String message) { 
       Log.d("Success", message); 

       Toast.makeText(getApplicationContext(), "Successful" + finalRootPath.toString(), Toast.LENGTH_LONG).show(); 
       Uri path = Uri.parse(finalRootPath + "/output.mp4"); 
       playVideo(path.toString()); 

      } 

      @Override 
      public void onProgress(String message) { 
       Log.d("progress", message); 
       pd.show(); 
      } 

      @Override 
      public void onFailure(String message) { 
       Log.d("failure", message); 
       pd.dismiss(); 

      } 

      @Override 
      public void onStart() { 
       Log.d("Start", "merge started"); 
      } 

      @Override 
      public void onFinish() { 
       Log.d("finish", "merge finish"); 
       pd.dismiss(); 
      } 
     }); 
    } catch (FFmpegCommandAlreadyRunningException e) { 
     e.printStackTrace(); 
    } 


    } 

は私の出力です：

Answer 1

コマンドを構成する方法が一貫していません。

あなたは、個々の引数に分割する必要があります ` 'ffmpegの-i /ストレージ//0/videokitをエミュレート：あなたがログに見れば

complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-c", "copy", "-map", "0:v:0", "-map", "1:a:0", rootPath + "/output.mp4"};
