[Ronald S. Bultje]

ffmpeg | branch: release/0.7 | Ronald S. Bultje <rsbultje at gmail.com> | Mon Oct  3 07:37:24 2011 -0700| [5d2b6006f0567629324613ee73b779acbaf8f039] | committer: Michael Niedermayer

mpegvideo: fix position of bottom edge.

It was wrong in colorspaces where horizontal and vertical chroma
subsampling are not the same, e.g. 422.
