• FFmpegMediaPlayer Stops When Network is Turned Off and Back On

  18 mai 2017, par Fallas

  I am currently working with FFmpegMediaPlayer in order to make a basic music player given a url. I got the basic functionality to work. On error, I show an error message, else I play the songs.
  The problem I am facing is, once the player starts, and I turn off my wifi and phone data, it stops the sound. Once I turn my wifi or phone data back one, I would like the player to continue but it simply stops. I have to stop and play again for it to continue.

  Is there a way to have the FFmpegMediaPlayer continue streaming ?

  This is what I have to initialize the player :

  mMediaPlayer = new FFmpegMediaPlayer();
  
      mMediaPlayer.setOnErrorListener(this);
  
      mMediaPlayer.setOnPreparedListener(this);
  
      mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
  
      mMediaPlayer.setOnBufferingUpdateListener(this);
  
      mMediaPlayer.setOnSeekCompleteListener(this);
  
  
  
      try {
  
          Uri uri = Uri.parse(radio_url);
  
          mMediaPlayer.setDataSource(mMainActivity, uri);
  
          mMediaPlayer.prepareAsync();
  
      } catch (IllegalArgumentException e) {
  
          e.printStackTrace();
  
      } catch (SecurityException e) {
  
          e.printStackTrace();
  
      } catch (IllegalStateException e) {
  
          e.printStackTrace();
  
      } catch (IOException e) {
  
          e.printStackTrace();
  
      }

  Then I have a function to handle when Play/Stop button is clicked :

  @Override
  
  public void onPlayButtonClicked(Button button) {
  
  
  
      if (radioInitialized) {
  
          mAnalytics.onStopButtonClicked();
  
          mMainLayout.loading(false);
  
          mMediaPlayer.pause();
  
       button.setBackground(mMainActivity.getResources().getDrawable(R.drawable.play_button));
  
          radioInitialized = false;
  
      } else {
  
          mAnalytics.onPlayButtonClicked();
  
          mMainLayout.loading(true);
  
          initRadio();
  
          button.setBackground(mMainActivity.getResources().getDrawable(R.drawable.stop_button));
  
          radioInitialized = true;
  
      }
  
  }

  Again, the basic functionality works, but I would like for it to continue streaming after wifi is turned back on.

• How to convert a video format into mp3 format using back end language script

  20 juillet 2017, par GeorgeTheGood

  I want to convert mp4 into mp3 with back end script (language doesn’t matter but preferably java or php). I know that there exists ffmpeg but I don’t want it to be done by hand. I want to build a website which requires link of a video and then converts it to mp3.

  aacenc : mark the preset 5.0/5.1 layouts correctly with back speakers
  The spec is correct, it does list these layouts as having rear speakers.
  
  Questionable how many decoders correctly interpret those correctly since
  
  side is way more popular.
  
  Also fixes fate-aac-yoraw-encode.
