精确控制视频播放进度/生成剪辑脚本的工具栏
It requires you to have `youtube-dl` (and also `ffmpeg`, I think) installed on your computer.
On Windows you may need to replace "youtube-dl" to the path to your youtube-dl.exe. Also, you may need to add "--ffmpeg-location [path to your ffmpeg.exe]".
How can I export the generated clip?
ex:
youtube-dl -f bestaudio "https://www.youtube.com/watch?v=saZIa1wYStg" \
-x --audio-format mp3 --audio-quality 192k \
--postprocessor-args "-ss 2950 -to 3000 -af loudnorm=I=-16:TP=-2:LRA=11" \
-o "output-%(id)s-2950-3000.%(ext)s"
I'm not sure how to paste this in cmd(yt-dl)
