Vu les logs je suppose que tu as Plex d'installé. Il y a beaucoup de mention du plex transcoder, essaye de désactiver les taches de fond de plex (création de vignette, détection d'intro, etc).

I just applied the specific settings in the XML form view and now it works, see attached file for an example.
