avcodec/mediacodecenc: set quality in cq mode >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.
