windows mjpeg codecs usually do only rgb formats, a few can do yuy2 too, but
probably with internal conversion (DR method 2).

for ffmpeg, my yuy2 hack is slow C conversion too...
anyway, we will need a fast planar yuv 4:2:2 to packed yuy2 converter...
(planar 4:2:2 is same as yv12, but y and u,v planes has the same height,
so u/v are only horizontally scaled down by 2)

But it can do RGB as well.
And it does yuy2 with conversion, so it still means double conversion in
this case...
