It might be faster here to put the "if (pix_fmt&1)" check outside the
loops.  If gcc does something sane with it that might not be necessary
though.  Also, (avctx->pix_fmt & 1) is not really obvious here.  Either
it should check for RGB48BE or there should be a comment.

Rest of the encoder looks fine to me.
