Subject: [RFCv1 05/12] media: mtk-vcodec: support single-buffer frames
Date: Tue, 28 May 2019 14:56:28 +0900 [thread overview]
Message-ID: <20190528055635.12109-6-acourbot@chromium.org> (raw)
In-Reply-To: <20190528055635.12109-1-acourbot@chromium.org>
From: Yunfei Dong <yunfei.dong@mediatek.com>
MT8183 will use a multi-planar format backed by a single buffer. Adapt
the existing code to be able to handle such frames instead of assuming
each frame is backed by two buffers.
