      protected void onCreate(Bundle savedInstanceState) {
  
          super.onCreate(savedInstanceState);
  
          setContentView(R.layout.activity_main);
  
  
  
          strAudioFolderPath = "/sdcard/Download";
  
          String s = "ffmpeg -i /sdcard/Download/testing.mp4 -i /sdcard/test.png -filter_complex 'overlay=10:main_h-overlay_h-10' /sdcard/Download/out.mp4";
  
  
  
          GeneralUtils.deleteFileUtil(strAudioFolderPath + "vk.log");
  
  
  
          PowerManager powerManager = (PowerManager) this.getSystemService(Activity.POWER_SERVICE);
  
          PowerManager.WakeLock wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "VK_LOCK");
  
          wakeLock.acquire();
  
          LoadJNI vk = new LoadJNI();
  
          try {
  
              try {
  
                  vk.run(GeneralUtils.utilConvertToComplex(s), strAudioFolderPath, MainActivity.this);
  
                  Log.e("Checking water marker", ">>>>>>>>>>>>>>>");
  
  
  
              } catch (Throwable e) {
  
              } finally {
  
                  if (wakeLock.isHeld())
  
                      wakeLock.release();
  
                  else {

• IBM Watson Speech to Text Audio Conversion on Node.js Web Application

  25 avril 2016, par Raquel Hosein

  The gist of the issue is that IBM Watson Speech to Text only allows for FLAC, WAV, and OGG file formats to be uploaded and used with the API.

  My solution to that would be that if the user uploads an mp3, BEFORE sending the file to Watson, a data conversion would take place. Essentially, the user uploads an mp3, then using ffmpeg or sox the audio would be converted to an OGG, after which the audio would then be uploaded to Watson.

  What I am unsure about is : What exactly do I have to modify in the Node.js Watson code to allow for the audio conversion to happen ? Linked below is the Watson repo which is what I am working through. I am sure that the file that will have to be changes is fileupload.js, which I have linked, but where the changes go is what I am uncertain about ?

  I have looked through both SO and developerWorks, the IBM SO for answers to this issue, but I have not seen any which is why I am posting here. I would be happy to clarify my question if that is necessary.
