[PATCH 7/9] media: mtk-vcodec: Add frame racing mode encode process
Irui Wang
irui.wang at mediatek.com
Mon Aug 16 03:59:32 PDT 2021
The frame_racing mode encoding is try to use the two venc cores:
frame#0 use core#0, frame#1 use core#1, frame#2 use core#0...,
Lock the device and enabe the clock by used core, for sequence
header encoding, it always used core#0.
