Subject: [PATCH v2, 10/14] media: mtk-vcodec: Add core thread
Date: Sat, 17 Jul 2021 16:12:29 +0800 [thread overview]
Message-ID: <20210717081233.7809-11-yunfei.dong@mediatek.com> (raw)
In-Reply-To: <20210717081233.7809-1-yunfei.dong@mediatek.com>
Core thread:
1. Gets lat_buf from core msg queue.
2. Proceeds core decode.
3. Puts the lat_buf back to lat msg queue.
Both H264 and VP9 rely on the core thread.
Signed-off-by: Yunfei Dong <yunfei.dong@mediatek.com>
