App does not report playback duration to Jellyfin

Issue description:

Hello,

I’m using a Jellyfin server (10.11.6) with the Listebrainz plugin (scrobbler).

While the “now playing” functionality works, when a track is finished Symfonium reports that the track was played for 0 ms, which causes the listen to be dropped and generates no scrobble.

I’m attaching Jellyfin server logs. They indicate that the app reports “playback stopped” three times (which already seems odd), but each time with a duration of 0ms.

Duplicate of many :wink:

Use the alternative mode in the plugin.

Sorry, I must have not searched properly then ; I didn’t find any duplicates.

Is this not a workaround though? In particular, I’d want to check if other players can still scrobble if I turned this on.

Can’t symfonium simply report playback duration as intended by the API?

No, because 1) Symfonium controls and expose the settings for marking played or not. 2) Symfonium properly report plays that happens offline and would be missed.

I don’t really see why that means the API call for playbackStopped( trackID, 0ms )

cannot be

playbackStopped (trackID, actualElapsedTimeInMS)

I’m afraid of other players not marking items as played (since that typically does nothing for music), which would break scrobbling from those players.

Again playcounts are managed by Symfonium + offline playbacks …

And yes play counts are important data for most users, and reporting the time would lead to invalid and uncontrolled playcounts between server and Symfonium.

Again there’s plenty of threads here explaining all that. The way scrobbles are handled in Jellyfin is very limited. A scrobble should occur when increasing playcount independently of how the playcount is generated (from the position or from the API).

This is something to be handled internally better in Jellyfin and the plugins to properly handle all cases and not just basic online only playback and uncontrolled playcount increase value.
