Unstable transcoding and Linux file permissions

Plex Media Server Desktops & Laptops
1

Server Version#: 1.32.5.7349

I migrated my Ubuntu to Debian 12 following @ChuckPa 's tutorial.

I applied the following permissions (the server rights on ubuntu were too permissive because I hadn’t set them up)
chown -R plex:plex "/var/lib/plexmediaserver

find /var/lib/plexmediaserver -type d -exec chmod 755 {} ;

find /var/lib/plexmediaserver -type f -exec chmod 644 {} ;

here I am with linux-compliant rights, but my plex no longer works properly when it needs to perform transcoding. The Dashboard says it’s transcoding, but I can’t see an image on the screen.

After searching and comparing with my plex on ubuntu, I realized that it was a file rights issue that was causing problems. I changed the rights of the /var/lib/plexmediaserver -type f files to 755, as for the directories, and it started working again.

Can this situation be improved or are my file rights, although not strictly compliant, still correct?

2

what does ‘groups plex’ and ‘ls -la /dev/dri’ show?

also what is the CPU?

I will also need the DEBUG logs ZIP file.
There must be something significant in there.

Here’s the zip of the logs

They were recorded yesterday with the d 755 and f 644 rights.

The last movie played is Patriots Day, and the transcoding worked, the one before that is Balde Runner and the transcoding was active but no image was playing.

Where is the transcoder temp directory ?

Is it on a local device or using network storage
-OR-
Did you move the PMS default directory ?

I ask because:

This type of error occurs when:

  1. The inotify table is full. The default on current linux kernels is 8192 → 65536 (dependent on memory). I do not see evidence of table full in your logs
  2. The transcoder temp directory (or remapped TEMP) directory is on a network location where file locking & notify does not work.
5

The transcoding directory is located on a 1 TO partition on a second SSD disk. The transcoding home directory is owned by plex :plex

The PMS default directory has not been changed.

I’ve just redone a transcoded playback of a movie with file rights at 644 (it doesn’t work) 19H38

Then the same film with file rights at 755 (it works) 19H45

6

  1. Show me the exact pathname please where you set ‘644’ permissions (ls -la)

  2. What is ‘19H45’ ? timestamp 19:45h?

This is the failure I find; playing the dolby vision content.
Now must know where you set 644 file permissions.

supplemental: Permissions for /tmp must be 777 so all system usernames can use the /tmp partition.

Yes, is timestamp

find /var/lib/plexmediaserver -type f -exec chmod 644 {} ;

This is not a /tmp partition in use for transcode, this a specific partition, only for plex transcode

It is from here that we find the files in 644. Currently they are in 755. I cannot modify them for the moment, I have two users viewing on the server.

Please look again.

The transcoder is attempting to use /tmp

Does user plex:plex have 777 permissions to /tmp (or appropriate ACL)?

10

Yes with 644 permission, The transcoder attempting to use /tmp
but with 755 permission , the transcoder use /transcode

I will setup a Debian 12 VM to test this.

I have never seen this behavior before

I think you’re focusing on the transcoder VIDEO files.
You want to be focusing on the AUDIO files I show above.
“chunk” and “media” are all video. There is no audio there.

13

to understand well,
you want me to test only with audio files?
I’ll do that tonight, I’m going to work

14

Where is this path please?

Is /transcode in a docker container or a real path on your server ?

I recognize we are having language difficulties.

I don’t want you to focus on audio.

The problem you’re showing me is with the audio

are video files. There is no audio in them.

We need to focus on why /tmp fails.

/transcoder is not in a container, it is a second ssd disk entirely dedicated to this task. it is mounted as directory in linux /transcode at the root

This is going to sound VERY strange.

  1. umount /transcode
  2. chmod 777 /transcode
  3. mount /transcode
  4. now set permissions to their normal plex:plex 755

If the base filesystem directory mount point doesn’t allow access correctly, mounting on top if it will behave very strangely. It is likely a Linux bug but has always been this way

Wow!
It worked.

Great job, thanks for your help

I’m glad it’s solved.

I apologize for not spotting it sooner.
