title: How to download 1080p + best audio using youtube-dl?
body: <p>I'm trying to download 1920x1080 video with 192kb/s audio but I'm unable to extract both.
  For example:</p>

  </code></pre>
  
  <p>I'm trying to merge the 1920x1080 video from 137 and 192kb/s audio from 22 (as it's the best available).</p>
  
  <pre><code>-f 'bestvideo[height&lt;=1080]+bestaudio/best[height&lt;=1080]' --merge-output-format mp4
  </code></pre>
  
  <p>But the audio bitrate of output file was 125kb/s.
  How can I download the required specifications?</p>
  
  <p>EDIT 1:
  Link for the example video: <a href="https://www.youtube.com/watch?v=i-c-K3pNtj4" rel="noreferrer">https://www.youtube.com/watch?v=i-c-K3pNtj4</a></p>
  
  <p>NOTE: I don't know too much about audio codecs but I want to select the best one so if possible, please provide the facts that can be used to identify the best audio if it outfactors the bitrate.</p>
