  Le fichier vides.txt peut etre tres gros et est un peu lourd a manipuler. On le remplace par un fichier unitaire .vide sur chaque gravatar concerne, ce qui permet un touch unitaire avant une recuperation pour eviter une double recuperation concurrente (idem sur le cache, on touch avant de recuperer pour eviter une double recuperation)

• Android UnsatisfiedLinkError using ffmpeg library

  5 avril 2012, par Bombastic

  I'm trying to use FFMPEG library in my Android application like this example here : AFPlayer . I have a builded and running version of this application and everything works fine, but when I tried to implement the same logic in my application it crashes everytime I start my media player. So the thing that I did was to copy and paste all files from afplayer's folders to my app (not sure if I have to do something else or if it's the right way,but it's my first touch with Android NDK and I'm not really sure how to do the things). Here is how I'm trying to start my DRadioMediaPlayer :

       player = new DRadioMediaPlayer();
  
      //player.setOnPreparedListener(this);
  
      //player.setOnCompletionListener(this);
  
      //player.setOnErrorListener(this);
  
      //player.setOnBufferingUpdateListener(this);
  
  
  
      //player.setAudioStreamType(AudioManager.STREAM_MUSIC);
  
      try 
  
      {
  
          Uri source = Uri.parse(playlist.getCurrentSource().toString());
  
          player.setDataSource(source);
  
          //player.setDataSource(playlist.getCurrentSource().toString());
  
          player.prepare();
  
  
  
          playbackState = DRadioPlayerService.PLAYBACK_STATE_BUFFERING;
  
      }

  This is how I load the library :

  static {
  
    System.loadLibrary("player");

  }

  and here is the exception which I'm getting :

      04-05 17:04:37.478: W/dalvikvm(686): No implementation found for native Lcom/nimasystems/android/radio2/DRadioMediaPlayer;.n_createEngine ()V

  </init>

  and here is the line where actually the exception it thrown :

  public DRadioMediaPlayer() {
  
    Log.d(TAG, "Create new MediaPlayer");
  
  
  
        n_createEngine(); // here
  
  
  
     }
  
  
  
  public native void n_createEngine();

  Any suggestions what actually can I do to fix this problem ? I've read all questions with similar issue here,but none of them worked for me.

  Thanks in advance !

• Executing process on cmd, does not process

  2 août 2012, par Z Jackobovski

  I am running ffmpeg from Java. Using it to convert flv files to mp3.

  When I run the code below, ffmpeg starts, creates a new file (the .mp3 one) but runs at 0% of CPU. When I stop the JAVA app (from netbeans) ffmpeg remains open and goes from 0% to 99% per Windows task manager (CTRL-ALT-DEL). Another weird thing is going on. The output from ffmpeg is not being printed.

  The thread is starting but for some reason java is not giving it any time to do its processing.

  Any suggestions on how to fix this ? Thanks.
