1. 背景
使用迅雷影音的“截取视频” 功能得到的视频片段在某些播放器下无法拖拽进度条，甚至无法播放，撰写此批处理实现视频无损修复（调用 ffmpeg ）。
2. 功能
- 列出批处理所在文件夹内的所有视频
- 检查视频存在的问题
- 依次修复（需要用户确认，“y” 执行“n”跳过）
- 使用快速修复模式
- 快速修复失败会使用重编码方式修复
3. 使用方法
- 下载 ffmpeg.exe 和 ffprobe.exe 并放到视频所在的文件夹
- 将本文下面提供的批处理源码拷贝并存到视频所在的文件夹
- 修改文本名称为：“修复视频.bat”
- 双击运行
- 根据控制台提示操作，你只需要3个动作：敲回车，敲"y" 或者 “n”
4. 批处理源码
