title: How can i add cover image on mp3 file using ffmpeg?
body: <p>I'm trying to convert audio file to mp3 and I want to add cover image into mp3 file.
  I tried this:</p>
  
  <pre><code>ffmpeg.exe -i "input audio file" -i image.png out.mp3
  </code></pre>
  
  <p>When conversion completes there is no cover image into mp3. 
  I tried and this which is from the official documentation of ffmpeg. The result is the same mp3 file without cover image.</p>
  
  <pre><code>ffmpeg -i input.mp3 -i cover.png -c copy -metadata:s:v title="Album cover"-metadata:s:v comment="Cover (Front)" out.mp3
  </code></pre>
  
  <p>Thank you in advance!</p>
