When the input color format is YUV, we need to do some external scale for CBCR. Like, * In YUV420 data format: cbcr_xscale = dst_w / src_w * 2; cbcr_yscale = dst_h / src_h * 2; * In YUV422 data format: cbcr_xscale = dst_w / src_w * 2; cbcr_yscale = dst_h / src_h; * In YUV444 data format cbcr_xscale = dst_w / src_w; cbcr_yscale = dst_h / src_h; Signed-off-by: Yakir Yang <ykk@rock-chips.com> Signed-off-by: Mark Yao <mark.yao@rock-chips.com> --- drivers/gpu/drm/rockchip/rockchip_drm_vop.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
