Preface

video id

Set a video id for the video

defined as

xxxxxxx/video/xxx
# video 后面的内容定义为视频id

ffmpeg

Download the video from station b. The audio and video are separated. You can also use PR or the like to merge the two. I chose to use this ffmaeg

This is mainly to download -------FFmpeg

It can be used in combination with python third-party libraries, or directly from the command line.

I chose to use the command line

other

Others are third-party libraries, just pip them
