Report listening data on offline tracks

[FrenchGithubUser]

First of all, thanks for the amazing work done here !

I often times have hole albums on my jellyfin server but only download locally the tracks from the playlists (my favorites), and listen to them. I like to see the latest playlist additions by setting all my playlists to auto-download, turn on offline mode, and go on the tracks tab, sorted by addition date. But this way, when I listen to the tracks, the amount played isn't updated.

Would it be possible to store this data temporarily, and then report it once offline mode is off ? Or, allow to see the offline tracks all at once, sorted by addition date, without having to turn on offline mode ?

It is somewhat possible to submit offline plays to the server, but only to the playback plugin. That isn't used to calculate the play count though. If we manually mark a track as played in Jellyfin, the play count is updated, but using the current time, which is wrong. Maybe we could add an option for this at some point, but it would be highly inefficient (it requires one request per listen).
