From 35d0783fca504997e1be30cfebfa8de042ea49ab Mon Sep 17 00:00:00 2001 From: ayaka Date: Sun, 26 Mar 2017 04:54:42 +0800 Subject: [PATCH] video: Add NV12_10LE40 pixel format This pixel format is a fully packed variant of NV12, a luma pixel would take 10bits in memory, without any filled bits between pixels in a stride. The color range follows the BT.2020 standard. In order to get a performance in hardware memory operation, it may expend the stride, append zero data at the end of echo lines.
