 ffmpeg no longer accepts creation_time metadata in its own format
 (YYYY-mm-dd HH:MM:SS) or in ISO 8601 format (YYYY-mm-ddTHH:MM:SS)
 as it did previously.  It looks like the problem was introduced by:

 }}}

 Note: creation_time was specified as 2012-09-09T17:45:00 but ffprobe
 shows 2011-12-31 00:00:00.  The same command worked as expected in
 earlier builds of ffmpeg.

 It works if the creation_time is specified as "2012 - 09 - 09T17:45:00".
