• Play video in Android using FFMPEG

  24 juin 2013, par Jagdeep Singh

  I had build FFmpeg library in Android(NDK) using this. But this example is too basic. It just checks if the video is present or not. What I want to do is just to play the video using FFMPEG. Is there any example or any code which can help me on this ?

  Thanks in advance.

• 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.

• Use pre-built libffmpeg.so in Android Project

  26 juin 2013, par Aditya Kumar Praharaj

  Is it possible to use a pre-built ffmpeg library , libffmpeg.so (well preferrably the one open-source) in my own Android Project ? If so , then how would you :

  1 . include it in your project directory ?

  2 . modify Android.mk given that it is a shared library ?

  Thanks
