title: How to retrieve HTTP headers from a stream in ffmpeg?
body: <p>I'm currently makeing an audio streaming app on Android. I'm using Android NDK combined with ffmpeg to perform that it's working pretty well so far.</p>
  
  <p>Right now I would like to retrieve the shoutcast metadata contained in the headers stream while streaming. Apparently ffmpeg doesn't provide a direct way to do that but I'm pretty sure it's technically possible to retrieve HTTP headers from the stream as we are receiving all the bytes while streaming.</p>
  
  <p>Does anyone know how to retrieve HTTP headers from a stream using ffmpeg?</p>
