BDW sprite planes simply do not support scaling, so that's expected.

To get mplayer to use another format you can pass eg. '-vf format=yuy2' to it.

As for the corruption, I'm getting it on my BSW too. With both YV12 and YUY2.
So a generic gen8 issue I suppose. For me it seems to depend on the horizontal
position of the window. When I see the corruption and I pause mplayer, then
move the window sideways a bit, the corruption remains in the image, but then
if I hit '.' to have it render another frame the corruption shifts or
disappears.

And even when I get the position correct to eliminate the green/purple
corruption, the results still look very blocky. Pretty much looks like it's
doing linear interpolation exactly the wrong around or something. Not quite
sure, but look like the vertical interpolation is the problem, horizontal might
be OK.
