Describe the bug

I installed the plugin and ran the "Detect Intros and Credit" tasks. After I started the series (I tested two series, same thing happened) it immediatly crashed with the error message along the lines of "The web player had a fatal error". After I ran the "Clear Intro Skipper cache", it started working again.

From the look of the error, the bug is not the plugin per-se but the plugin having an issue with how the file is being recorded. Is there actually a file in your library with the name -1.mp4?

[C0RR1T]

I don't think so (I currently don't have access to my file structure since Im on mobile, I can look at it in like 2-3hrs). I think its in correlation to the intro skipper plugin since the native player in the android app works as intended and the webplayer doesn't... (and the webplayer works when I clear the intro skipper cache aswell, as mentioned in the issue).

Just to clarify, “per se” means it is related to the plugin, but not necessarily directly caused by the plugin. What i was trying to diagnose was whether the issue was related to how the plugin is interpreting the file names. It has been known to struggle with special characters and the name of the file it is listing seems a bit unusual.

[C0RR1T]

Alright, thanks for the clarification :) I'll look at the file names and report any that could cause the issue.

So this is the file structure I have for my tv shows: I didn't notice any weird characters in the show name, could be because sonarr renamed them for jellyfin. The files are all .mkv if that helps aswell

[C0RR1T]

It seems like it's an issue with hardware decoding, which is pretty weird since it worked fine until now. Anyway, thanks alot for your help.

Interesting. Perhaps we may need to investigate the parameters being used to analyze the files and either align with or deviate from the playback settings if it only happens with the plugin cache. It is also possible that was just coincidence, though.

I think it was a pure coincidence, it totally runs fine now. Thanks for your help :)
