In case of the file,  tiny_duration_example.mp3
there is a xing header in the file.
So in mpegaudioparse, the duration is calculated based on the xing header and
updated
    gst_base_parse_set_duration (GST_BASE_PARSE (mp3parse), GST_FORMAT_TIME,
        mp3parse->xing_total_time, 0);


But in case of mp3 encoded by lame encoder, there will be no xing header. So
duration is not being updated.
But in case of files having more than 57 frames(1.5 second duration, varies on
framerate)
here parse->priv->update_interval is calculated to be 57
in baseparse, the duration gets updated
  else if (parse->priv->update_interval > 0 &&
      (parse->priv->framecount % parse->priv->update_interval) == 0)
    gst_base_parse_update_duration (parse);


So for files with less than 57 frames the duration is never being calculated.
