Can't create optimised version "unable to convert"

Plex Media Server NAS & Devices
1

Server Version#: 1.21.1.3830

This has me stumped. The server can write to the movies’ folder, because the “Plex Versions” directory gets created.

And I stumbled across an error in the log:

transcode-error
transcode-error1640×242 113 KB

Any ideia what could be going on?

I’m still trying to solve this issue, even tried to link the devices onto the docker-compose file, but so far it still won’t convert:

version: '3.2'

services:
  plex:
    image: plexinc/pms-docker:latest
    container_name: plex
    restart: always
    network_mode: host
    environment:
      - PLEX_CLAIM="${PLEX_TOKEN}"
      - ADVERTISE_IP="https://plex.${DOMAIN_NAME_2}/web/"
      - PLEX_UID=1000
      - PLEX_GID=1000
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /dev/rtc:/dev/rtc:ro
      - /mnt/hdd/Plex/transcode:/transcode:rw
      - /mnt/NAS/hdd/Tv Shows:/data/tvshows:rw
      - /mnt/NAS/hdd/Movies:/data/movies:rw
      - /mnt/NAS/hdd/Music:/data/music:rw
      - /mnt/NAS/hdd/Podcasts:/data/podcasts:rw
      - /mnt/NAS/hdd/Videos:/data/videos:rw
      - /mnt/hdd/Plex/:/config:rw
    devices:
      - /dev/dri/card0:/dev/dri/card0
      - /dev/dri/renderD128:/dev/dri/renderD128

    labels:
      - traefik.enable=false

It always seems like the command can’t find a codec. Should I be linking to it from outside as well?

The fix for this problem seemed to be adding the exec flag to the fstab file, since this case uses a USB HDD to store the library and the transcode folders. All other media was saved in a NAS shared folder.

…adding the exec flag to the fstab file…

I’m having similar issues. I’m not sure if this fix will work for me, but I’m willing to give it a try. Could you please explain where, exactly, the exec flag goes in the fstab file? And which fstab file (host or Plex container)?
