 libavformat's http support does not appear to export these headers, which
 are needed to display metadata to the user when playing these streams.
 mplayer supports them.

 These headers are dumped at the start of a streamed song, for example:
 "icy-genre:METAL, ROCK, ALTERNATIVE". Note that these can be updated mid-
 stream (e.g. on song change), and libavformat both needs to read that, and
 notify the application of it.

 Useless required dump of ffplay output:
