Subject: [PATCH v13 02/13] media:Add nv12mt_8l128 and nv12mt_10be_8l128 video format.
Date: Tue, 30 Nov 2021 17:48:03 +0800 [thread overview]
Message-ID: <c7a7bf7a1d3c10a0e28064e37a472cbd45470e82.1638263914.git.ming.qian@nxp.com> (raw)
In-Reply-To: <cover.1638263914.git.ming.qian@nxp.com>
nv12mt_8l128 is 8-bit tiled nv12 format used by amphion decoder.
nv12mt_10be_8l128 is 10-bit tiled format used by amphion decoder.
The tile size is 8x128
