Comment (by b_jonas):

 The output has changed but is still not what I expect.  Testing with the
 Zeranoe ffmpeg build for windows x64 "ffmpeg version N-61870-g62094e2
 Copyright (c) 2000-2014 the FFmpeg developers built on Mar 26 2014
 22:12:29 with gcc 4.8.2 (GCC)", using the commands in my report, I get the
 following output.

 I expect all 0 values.
