If you know, you know. The `ffmpeg` command line options. 🤨

Let me collect some function definitions on this page. I'll be adding more over the years to come, for sure.

function video-resolution
    ffprobe -v error -select_streams v:0 -show_entries stream=width,height -of default=nw=1 $argv
end

# remember to download lower resolutions for smaller laptops
yt-dlp --list-formats URL
yt-dlp --format N URL

# download audio only
yt-dlp --extract-audio --audio-format mp3 URL

# extract audio without converting
ffmpeg -i input.mp4 -vn -acodec copy output.aac

# convert to mp3
ffmpeg -i input.mp4 output.mp3
