pip install --user numpy Matplotlib scipy opencv-python pytesseract
不过我不得不说一句，作者的依赖管理观念着实不强，版本号 requirements.txt 和 venv 都没有 🤔
而且也没用 argparse，直接 sys.argv[1] ……

今天来给大家分享个脚本…… 是我从 https://github.com/shawnsky/extract-subtitles 重构的版本
原版几乎不能用（滑稽
经由本苏久坐劳累后妙手回春就又可以用了（跑

其实这个项目本来就不适合用 Python 写
原作者内存优化得太垃圾，把所有帧都放内存里…… 我这 4G 处理个 4 分钟压缩后 4M 的小视频都撑不过 1:00
我正在考虑是添加一个 gc 内存压力提示呢，还是用其他语言重写呢，还是换 pypy 呢 🤔
反正最后一部分 cv 是不可以继续用 Python 的，内存压力实在是太大了……

我觉得可以做一个 GUI，来支持时轴框选歌词区域。

horizontalLayout {
  TextureView,
  Sidebar(verticalLayout {
    playerTime,
    horizontalLayout { playerControl, btnNewCrop }
    ListView(crops/*time rect*/),
    TextView /*current_subtitle*/,
    TextArea /*time_subtitles*/
  })
}

……是应该进一步学习 GUI 了
