Raspberry pi Playback failed due to a fatal player error.

[Zraner]

I am migrating my movie collection from Plex to Jellyfin, and it’s been quite a challenge. After managing to get the folders to appear in the libraries, it is not reading all the movies I have. It only detected 102, but I have quite a lot more (around 350).

In addition to this issue, when I try to play any of the files it does recognize, I get an error message: "Playback failed due to a fatal player error."

I have searched through forums and the internet and tried several things, for example, installing Jellyfin's ffmpeg6, but I haven’t been able to get it to work in any way. It won’t play on the computer or any device I’ve tested.

I have managed to get all the series to appear, every time I identified one, the next one appeared, but now all the ones I have identified appear without seasons or episodes, I have checked that everything is well named, for example The Magicians/Season 01/The Magicians s01e01.

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.
