解析视频分辨率和时长

下载工具

使用的工具是：FFmpeg 分为win 和 linux
需要提前安装 FFmpeg

windows版本

linux版本

有道笔记

windows 安装

将下载的进行解压，配置系统环境变量

CMD命令行解析视频信息

配置结束后，可以使用

ffmpeg.exe -version查看是否安装成功

解析视频信息：ffmpeg.exe -i D:\\test\\视频\\00aad32fff808081465a.mp4

Linux安装

具体安装步骤可以参考：https://cloud.tencent.com/developer/article/1711770
