title: ffprobe select audio and video streams
body: <p>I use this code for extracting video information by <em>ffprobe</em> :</p>
  
  <pre><code>ffprobe -show_streams -of json -v quiet -i input.mp4
  </code></pre>
  
  <p>The information of all streams appears in the output while I need only the information of v:0 and a:0 streams.</p>
  
  <p>I know that there is <code>-select_streams</code> option for stream selection but it accepts only one argument like: <code>-select_streams v:0</code>.</p>
  
  <p>Can I use <code>-select_streams</code> by two arguments <code>v:0</code> and <code>a:0</code> or using it twice? </p>
