yuy2 doesn't seem to work at all here; it gives a colorspace incompatibility
error and exits.

I don't have that behavior at all; the corruption seems to be entirely
position-independent here.  Though it's possible that some combination of
mplayer2 and compositing is causing the video decoding on my system to always
occur at the same offset in an off-screen buffer unless fullscreened.
