I’m running Plex v 1.25.3.5385 on a Ubuntu 20.04.3. I was using and enjoying the intro skip for a few months and then I noticed it stopped working. I’ve kept up on the newest version and none have fixed the issue. I’ve unchecked the “Generate intro video markers” and rechecked it, analyzed media in my TV library, but nothing has fixed the issue.
Do you have the library task enabled under Settings → Library → Generate Intro Video Markers?
You mentioned a check box; that’s to enable it for the specific TV Shows library, but the path I just gave above controls whether the server does it at all.
I’m having the same types of issues. Some episodes will work just fine, while others I cannot get Plex to detect intros on whatsoever. When trying to force w/ a manual analyze, I get things like this in the logging:
IntroDetector: Less than half of episodes have an intro. Clearing intros for [222485]
Updating part with ID=190439 [<Show directory & Name redacted>.mkv]
Doing expensive tags write for [Show title redacted] because something changed.
Activity: updated activity 9fbbfb91-50e2-4f7b-ac9f-3db79cdefe0d - completed 100.0% - Detecting intros
Then, when I go and look at the XML file for the show, nothing has changed.
No idea what is going on, but something isn’t right.
