Comment (by b_jonas):

 I (the original reporter) would like to note that this problem is not
 exclusive to Windows.  I have reproduced this on Linux amd64 with vanilla
 ffmpeg version N-51215-g428e9da built on Mar 22 2013 23:36:22 with gcc
 4.7.1 (GCC).  I have an all-zero input created with the same command as in
 the report, and decoded with commands very similar to above, only I had to
 change `-vf format=pix_fmts=rgb24` to `-vf format=rgb24`.
