Comment (by gwg):

 Great suggestion, cehoyos, thank you. Here's the url to the full example
 mp3, uploaded on datafilehost: http://www.datafilehost.com/download-
 1d3bb7d1.html. This file should fail when it's piped, but decode
 successfully when it's passed with the "-i" flag in a normal invocation,
 as described in the original bug.

 I will add that it's also successful if the input format is passed as a
 parameter to the piped invocation, like this:
 {{{
 cat ffmpeg_unpipeable.mp3 | ffmpeg -v 10 -f mp3 -i - testout.wav
 }}}
 The above invocation is successful, and produces output that seems pretty
 much identical to a normal non-piped invocation.
