• Getting an error while using JAVE library in an Android project

  27 mai 2015, par Archer2486

  I’m using an external library called JAVE in my Android project in order to extract the audio from a video file.

  My code :

   public void extractAudio() {
  
      File source = new File(Environment.getExternalStorageDirectory().getPath() + "/test.flv");
  
      File target = new File(Environment.getExternalStorageDirectory().getPath() + "/test.mp3");
  
      AudioAttributes audio = new AudioAttributes();
  
      audio.setCodec("libmp3lame");
  
      audio.setBitRate(new Integer(128000));
  
      audio.setChannels(new Integer(2));
  
      audio.setSamplingRate(new Integer(44100));
  
      EncodingAttributes attrs = new EncodingAttributes();
  
      attrs.setFormat("mp3");
  
      attrs.setAudioAttributes(audio);
  
      Encoder encoder = new Encoder();
  
      try {
  
          encoder.encode(source, target, attrs);
  
      } catch (IllegalArgumentException e) {
  
          e.printStackTrace();
  
      } catch (InputFormatException e) {
  
          e.printStackTrace();
  
      } catch (EncoderException e) {
  
          e.printStackTrace();
  
      }
  
  }

  These are the errors I get :

  I’m rather new to Android development and I’m not really sure what’s the problem here. I’d appreciate any help.

• show tracked object in Video using OpenGL

  12 octobre 2013, par user1958219

  I am extending an existing OpenGL project with new functionality.

  I can play a video stream using OpenGL with FFMPEG.
  Some objects are moving in the video stream. Co-ordinates of those objects are know to me.

  I need to show tracking of motion for that object, like continuously drawing a point or rectangle around the object as it moves on the screen.

  Any idea how to start with it ?
