Subject: [PATCH v2,16/21] media: medkatek: vcodec: support one plane capture buffer
Date:   Mon, 6 Nov 2023 20:04:18 +0800
Message-ID: <20231106120423.23364-17-yunfei.dong@mediatek.com>
In-Reply-To: <20231106120423.23364-1-yunfei.dong@mediatek.com>

MIME-Version: 1.0

Content-Type: text/plain
Precedence: bulk

The capture buffer has two planes for format MM21, but user space only
allocate secure memory for plane[0], and the size is Y data + uv data.
The driver need to support one plane decoder for svp mode.
