As much as a copout it is, I'm tempted to say "not gstreamer".
Using mjpegtools' mpeg2enc (which is what gstreamer's mpeg2enc element uses)
also doesn't get it right, and it triggers lots of valgrind reports (somewhat
less of them when using a nice size like 256x256, which lends credence to the
theory that it doesn't like weird sizes).
Also, luma seems correct, it's only chroma that's using a bad stride. I've
tried various hardcoded strides to see if anyone of them actually worked, and
none does. So the issue is more complicated that just bad stride calculation,
though it seems closely related.
