Description

yt-dlp is not outputting 'dislike_count' / 'average_rating' for Youtube (This happened after YT had hidden public dislikes count).
However Chrome extension "Return YouTube Dislike" is able to retrieve dislikes count. So I assume the count is still available through some alternative API.

From the extension's description:

Starting December 13th 2021, YouTube removed the ability to see dislikes from their API.
This extension aims to restore power to users by using a combination of archived like and dislike data, as well as the likes and dislikes made by extension users to show the most accurate ratings.

MinePlayersPE, thanks for the explanation.

[pjta]

Well, that Chrome extension has a public API https://github.com/Anarios/return-youtube-dislike
Maybe consider using it ?

[MinePlayersPE]

Doesn't really make sense to fetch from a 3rd-party API for an extractor

[pjta]

I understand the reluctance to use a 3d-party API.
But in the current situation when there are no other options, there is still some sense. The 'average_rating' (even approximate) is nice to have when bulk/playlist/channel downloading and filtering by best rating.

(Not trying to push you, just sharing my reasoning. So totally up to you.)

[pukkandan]

Totally understand where you are coming from. But I agree that it doesn't make sense in the core program, especially considering we have the ability to load plugin Postprocessors.

I personally use a custom PP to do this. I'll clean up the code and release it as a plugin
