title: FFMpegConverter. ConvertLiveMedia method doesn't work
body: <p>I need to convert files from AWS cloud, which mounted like a local drive by using TntDrive. 
  I tried to use <code>FFMpegConverter.ConvertMedia</code> method, but it works slow. In another question someone explained to me next:</p>
  
  <p>"It looks like you need to use the <code>FFMpegConverter.ConvertLiveMedia</code> method instead of the FFMpegConverter.ConvertMedia method to achieve this. Overall you will still find that you will be probably I/O bound rather than CPU bound."</p>
  
  <p>But next code didn't work for me: </p>
  
  <pre><code>static void Main(string[] args)
          {
              string input_path =
                  @"D:\WAV\ALBUM1\UNDER_ALBUM1\APOV01_10 POV 8_MAIN.WAV";
              string dest_path = @"D:\result.mp3";
              using (FileStream inputStream = new FileStream(input_path, FileMode.Open))
              {
  
                  var converter = new FFMpegConverter();
  
                  var result = converter.ConvertLiveMedia(
                      inputStream, "WAV",
                      dest_path, "MP3",
                      new ConvertSettings
                      {
                          AudioSampleRate = 44100,
                          CustomOutputArgs = " -b:a 192k "
                      }
                      );
                  Console.ReadLine();
              }
  
          }
  </code></pre>
  
  <p>What's wrong with my code ? </p>
