Certain files are being analyzed on every scan

It seems that files–especially duplicates, that are already recognized/matched/analyzed are being analyzed again during a library scan, which is seemingly slowing down the scanning process.

These appear with the words, didn't exist, can't skip which is rather ambiguous because these already exist in Plex.

~ $ tail -f /var/lib/plexmediaserver/Library/Application\ Support/Plex\ Media\ Server/Logs/Plex\ Media\ Server.log|grep "didn't exist"

Which corresponds to FFMPEG processes:

I’m seeing the same issue

I think this should improve when using the recommended file naming & organization conventions. I’m not sure which combination of things triggers it specifically.

Hrmph. Maybe not. I had a couple movies that were behaving that way, and renaming them to be correct addressed the problem.

But I also have a couple of movies that are named correctly, and they’re still exhibiting the “can’t skip” log message.

And renaming some other problem files, even slightly, was enough to stop this from happening.

So it seems like naming isn’t the (primary? only?) issue. Perhaps something to do with the file modification tracking in the database, and/or multi-version detection.

So I’m not sure!

Are there other video files in the same directories as the files getting this message?

OR

Do you have other Versions of these movies?

OR

Do you have other (empty) directories that would match these same movies?
