Trakt plugin scrobbles, but wrong video length on trakt.tv

[aptalca 70]

Hi, I've been having some issues lately with partially watched TV episodes reverting to unwatched after a trakt sync. I kept wracking my brains and finally figured out what's causing it.

While I'm watching the episode, scrobbling works and trakt.tv website shows the episode as being watched, but it shows the total video length as "3:00" (3 hours) even though the actual length is about 45 minutes. So when I stop it at about 17 minutes in, trakt.tv thinks I'm only at a very low percentage and I'm guessing it discards the partial watched state. The next time trakt plugin does a sync, it reverts the watched status on emby to unwatched, losing my spot in the episode.

It only happens on some media, not all. I'd be happy to provide some details if you let me know what exactly you need.

Here's one episode it happens to every time:

And there are 6 embedded DVDSUB subtitles.

The length of the video is 45 minutes, but Trakt.tv website displays 3:00 as the length while scrobbling.

 

Thanks

And here's a screenshot of Trakt.tv while scrobbling:

Hi, that's really odd because we don't actually send the runtime over to trakt. We send the playback progress percentage.

Huh, that's really weird then. Thanks for the reply. I'll do a little more troubleshooting with that in mind.

[aptalca 70]

A couple of observations:

1) It doesn't look like trakt api is updated when I seek in the video, because if I start the episode from the beginning and seek to the half way point and start again, trakt.tv still shows the playback in the beginning.

2) If I stop playback at the halfway point, and then start playback again (resume), trakt.tv shows the playback at the halfway mark of a 3 hr video.

That all confirms the percentage is sent by emby correctly.

I also tried playback on a different media server with an external app called plextraktsync doing the scrobbling and trakt.tv displays the runtime as 47 minutes, which is also what the trakt.tv website lists the episode length as: https://trakt.tv/shows/v/seasons/1/episodes/3

I'll try to see how plextraktsync scrobbles and whether they send the runtime info or not

[aptalca 70]

Ugh, this is really dumb. Trakt.tv has duplicate listings for the show and its episodes:

https://trakt.tv/shows/v/seasons/1/episodes/3

https://trakt.tv/shows/v-1984/seasons/1/episodes/3

In one of them, the episodes are listed as 47 minutes long, and that's what plex scrobbles to.

The other one lists the episodes as 180 minutes long and that's what emby scrobbles to.

It is clearly a trakt.tv issue and I'm reporting it to them.

That's interesting. Thanks for the update. Let us know what they say.

[aptalca 70]

I reported the duplicate entries to trakt.tv and they merged them. Now the runtime is correct on trakt.tv and the scrobbles and partial watched status syncs are done properly.

Thanks so much for pointing me in the right direction.

Thanks for the feedback !
