That doesn't seem to make any sense :) If VPP can handle YUY2, it shouldn't
matter if the encoder comes afterwards or not, and even less if the JPEG or
another encoder comes afterwards.

Either that comment is wrong, or what they mean is that the JPEG encoder can
directly take YUY2 without conversion.
