Subject: [PATCH 5/6] drm/rockchip: vop: correct the source size of uv scale factor setting
Date: Thu, 14 Jul 2016 11:33:27 +0800 [thread overview]
Message-ID: <1468467207-6715-1-git-send-email-mark.yao@rock-chips.com> (raw)
In-Reply-To: <1468467090-6108-1-git-send-email-mark.yao@rock-chips.com>
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;
