 == Sample file ==

 == Other info ==

 This looks like https://trac.ffmpeg.org/ticket/5645, except that I've
 built from master (git://source.ffmpeg.org/ffmpeg.git) and see
 [http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=d693392886b8454c818e384c816b9ede53c570d8
 d693392] in my Git rev history, so I should already have that fix.  Here's
 my revision of ffprobe (ffmpeg shows the same):
