Zhao Zhili 287e22f745 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.

Fix #10689

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation
