Subject: [PATCH 6/9] media: mtk-vcodec: Add new venc drv interface for frame_racing mode
Date: Mon, 16 Aug 2021 18:59:31 +0800	[thread overview]
Message-ID: <20210816105934.28265-7-irui.wang@mediatek.com> (raw)
In-Reply-To: <20210816105934.28265-1-irui.wang@mediatek.com>

Frame-racing mode encoding need more venc working buffers, it
will break the compatibility if we just add venc_vsi in AP-Kernel
but not in firmware, so add a new venc driver interface to
distinguish the sigle_core_mode and frame_racing mode.

The new driver interface can be used for different codecs in
the future.
