Update: Since a while,
youtube-dl
isn’t as powerful as it is. Fortunatelly another fork exists :yt-dlp
. Use this instead
Youtube recently got this “chapter” concept where it fragment a long video with chapters. I think this data might be parsed from the description of the video done, as they already parse any timestamp available for a while now.
Thanks to youtube-dl
, we can download thena video and the metadata which now contains this chapter data.
