Raspberry pi Playback failed due to a fatal player error.

The way you have your movies organized is problematic.  While having movies "loose" in the movies root folder is fine, the file names are problematic.  EVERY part of the file name is used for querying for metadata.  The movie name also needs to pretty closely match TMDB (the default metadata provider) if there are movies with similar names.

For example.

Code:

/media/pi/Peliculas/Jurassic.park.3.(2001).(Spanish.English.Subs).BDrip.1080p.x265-AC3.by.JJ.mkv

I'm not sure if this is a movie that isn't being added, but everything after (2001) should be removed.  Ideally, you'd also add the TMDB ID to the end for consistent, reliable, identification.  And the movies should be in their own folder.  But this isn't required if you don't intend to add extras.

Code:

/media/pi/Peliculas/Jurassic.Park.3.(2001).[tmdbid-331]/Jurassic.park.3.(2001).[tmdbid-331].mkv"

Regarding the playback errors.  I see some permission issues.

Code:

[2025-03-30 06:21:39.971 +02:00] [ERR] Error processing request. URL "GET" "/Videos/3b3a950331bcd9e7a2391870cc4994c7/stream.mkv".
System.UnauthorizedAccessException: Access to the path '/media/pi/Peliculas/Jurassic.park.3.(2001).(Spanish.English.Subs).BDrip.1080p.x265-AC3.by.JJ.mkv' is denied.

I am pretty sure exit code 243 is a permission error.

Code:

MediaBrowser.Common.FfmpegException: FFmpeg exited with code 243

Permission issues could possibly explain your issues identifying shows.
