Aggregate content from other streaming services into Jellyfin library

[TOMillr]

Alongside my local media files, I have bought licenses to a lot of movies and tv shows across different different streaming services like iTunes, Prime Video and Vudu over the years. However, I sometimes lose track of what content I already own and where I bought it from.

There should be a way to add content bought on services like Vudu or Apple TV to the Jellyfin library. Movies or tv series I have access to should show up in Jellyfin like native files, but for playback Jellyfin would deep link to the corresponding app.

Both Channels and Infuse have implemented this feature with the help of what they call "Stream Links":

With Channels DVR Server, you can import movies and TV shows from streaming services right into your library.
This is a simple way to aggregate content from other sources into your Channels library.

Stream Links are simple plain text files with URLs pointing to content on other services. They import into your Channels library just like Local Content. (...) Instead of a video that is played back, Channels knows that they are links and will open the appropriate streaming app to play them.
