Chapter Skipping for SponSkrub Chapters in downloaded YT Videos

Summary Ask:

Skip SponSkrub - SponsorBlock Chapters in downloaded yt videos via Chapter Titles

---

The Command Line Application: yt-dlp allows users to easily/automatically use SponSkrub to create video Chapters based on the SponsorBlock API.

Because of this, downloaded videos can have chapters for: Sponsors, Introductions, Outros, Interactions, Self-Promos and Non-Music sections.

I haven't been able to get the lua script of chapterskip to automatically skip these Chapters, but I think it would be cool to integrate SponSkrub Chapter titles into the type of content that is skipped with the mpv_sponsorblock lua script.

Thanks :)

Type of chapters that could be skipped:

[po5]

chapterskip definitely can skip those, but I can look into adding support in this script.
Could you send me list of chapter names that sponskrub generates for start & end times of various categories?

The plugin already has all the parts needed for skipping sponsored sections, since it works fine when streaming files.

Both youtube-dl and yt-dlp adds the url of the source to the PURL field in the files metadata. (you can check it with mediainfo)

so around https://github.com/po5/mpv_sponsorblock/blob/master/sponsorblock.lua#L397, you could change it to something like

local purl = mp.get_property("metadata/by-key/PURL", "")

youtube_id = nil
for i,url in ipairs(urls) do
   youtube_id = youtube_id or string.match(video_path, url) or string.match(video_referer, url) or string.match(purl, url)
end

and it should work, does for me with downloaded files
