Subject: [PATCH v4 02/13] media: v4l: add some definition of v4l2 colorspace/xfer_func/ycbcr_encoding
Date: Tue, 20 Jul 2021 09:43:21 +0800 [thread overview]
Message-ID: <d63b34381eec0ae47bf39dd2b88d2bc8994c269d.1626743758.git.ming.qian@nxp.com> (raw)
In-Reply-To: <cover.1626743758.git.ming.qian@nxp.com>
Some definition of colorspace/xfer_func/ycbcr_encoding
are defined in ISO, but missed in V4L2,
so add some definition according VPU driver's requirement
