No:
width * height * colorspace byte length / 8
768 * 576 * 12 / 8 = 663552

As you can see MPlayer already figured it out what value it should be
from width, height and colorspace format and that's why it reports an error.

And I think you could safely omit "size" value as you give width, height
and colorspace format.
