Comment (by Jarno Suni):

 It took me few hours to get the required ffmpeg binary (with no extra
 codecs; not by the instructions you told me to search for), and then few
 minutes to do the test. I could not use the original stream because it is
 no more available. I happened to find one local radio stream that uses a
 supported open format.

 I unplugged ethernet cable for few minutes and reconnected. ffmpeg could
 neither proceed nor quit; it did not react to q, so I pressed Ctrl-C to
 interrupt to get this:

 {{{
