From: Zhao Zhili <zhiliz...@tencent.com>
>From AOSP doc, these values are device and codec specific, but lower
values generally result in more efficient (smaller-sized) encoding.
For example, global_quality 50 on Pixel 6 results a 1080P 30 FPS
HEVC with 3744 kb/s, while global_quality 80 results 28178 kb/s.
Fix #10689
