  • Problems with ffmpeg command line on android

    17 mai 2017, par user2193172

    I managed to compile the ffmpeg Static build. But when I am trying to call the ffmpeg command line I get a Java IOException : No such file or Directory.

    My code is as follows :

    public void merge_video(View view){
    

    
    if(ffmpeg_file.exists()){
    
          Log.d(null, "ffmpeg exists");
    
      }else{
    
          Log.d(null, "Could not locate ffmpeg in the folder");
    
      }
    

    
      File file1 = new File("/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_22.mp4");
    
      if(file1.exists()){
    
          Log.d(null,"File 1 exists");
    
      }
    
      File file2 = new File("/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_28.mp4");
    
      if(file2.exists()){
    
          Log.d(null,"File 2 exists");
    
      }
    

    
      String[] ffmpegCommand = new String[5];
    
      ffmpegCommand[0] = "/mnt/sdcard/com.ffmpeg_test/ffmpeg";
    
      ffmpegCommand[1] = "-i";
    
      ffmpegCommand[2] = "concat:/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_22.mp4|/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_28.mp4";
    
      ffmpegCommand[3] = "copy";
    
      ffmpegCommand[4] = "/mnt/sdcard/com.ffmpeg_test/output.mp4";  
    

    
      try {
    
          Process ffmpegProcess = new ProcessBuilder(ffmpegCommand).redirectErrorStream(true).start();
    

    
          String line;
    
          BufferedReader reader = new BufferedReader(new InputStreamReader(ffmpegProcess.getInputStream()));
    
          Log.d(null, "*******Starting FFMPEG");
    

    
          while((line = reader.readLine())!=null){
    

    
              Log.d(null, "***"+line+"***"); 
    
          }
    
          Log.d(null,"****ending FFMPEG****");
    

    
    } catch (IOException e) {
    
        e.printStackTrace();
    
    }
    
  }

    The LogCat print is as follows :
