Jellyfin ratings

[Druidblack]

Updated to the second version.

The new version adds additional ratings from AniList, Kinopoisk, AlloCiné, Douban, and certifications from Metacritic and Rottentomates.

Differences between the second version and the first:

1. Getting more ratings and additional certifications from Metacritic and Rottentomates sites

2. Due to additional data sources, the data takes a little longer to load than in the first version.

3. Due to technical limitations, the code that integrates into the jellyfin page has a number of limitations. Such as unstable downloading of additional ratings from AlloCiné, Douban sites and obtaining certificates from Metacritic and Rottentomates sites. This is due to the use of free proxy servers.

4. Additional ratings (AniList, Kinopoisk, AlloCiné, Douban) will be uploaded only if the title and release year are found on the websites. Otherwise, there will be no data.  This is done to avoid receiving erroneous data.
