Python实现视频片头和片尾添加（不实用）
参考的原代码，运行提示：
RuntimeError: imageio.ffmpeg.download() has been deprecated. Use 'pip install imageio-ffmpeg' instead.'
直接删除掉这行：imageio.plugins.ffmpeg.download()
改为：

剪辑过程调用了 python安装目录下的\Lib\site-packages\imageio_ffmpeg\binaries\ffmpeg-win64-v4.2.2.exe
选择了一个大约400M的mp4，测试拼接，结果发现这个代码不实用!
想像中应该是这样：读一个mp4的尾，读另一个mp4的头，将头和尾连接越来，几秒钟完事。
现实是这样的：代码运行了10分钟以上，预计完成时间在不停增长，似乎永远停留在4%进度上。
