title: Reading metadata from online mp3-file
body: <p>I would like to read the mp3 <code>bitrate</code> of an online MP3 file, f.e. <a href="http://www.ntonyx.com/mp3files/Morning_Flower_%28Fragment%29.mp3" rel="nofollow">this one</a>, preferrably without downloading it in its entirety.</p>
  
  <p>I've been able to find out that ffmpeg allows one to do this, f.e. like so:  </p>
  
  <pre><code>ffmpeg -i http://physics.ujep.cz/~mmaly/mp3/Mozart/Mass_in_C_Minor_New_by_Levin/sbory_vyssi_kvalita/01_Kyrie.mp3
  </code></pre>
  
  <p>but I wasn't able to find a portable way to do this. (pyffmpeg requires a C compiler as well as Cython and keeps throwing new error messages at me every time I resolve one)</p>
  
  <p>If anyone has any tips/links/knows where to get further ideas, I'd be very grateful!</p>
