I ran into what I belive is the same issue with xineliboutput not starting because of missing "decoder plugins" mentioned in logs
Nov 20 20:58:48 MLD-rpi4 user.debug vdr: [25266] [vdr-fe] Using xine-lib config file /etc/vdr/plugins/xineliboutput/config
Nov 20 20:58:48 MLD-rpi4 user.err vdr: [25266] [vdr-fe] FATAL: Required xine video decoder plugins are missing! Please install plugins.
Nov 20 20:58:48 MLD-rpi4 user.err vdr: [25266] [vdr-fe] (ERROR (xine_frontend.c,173): File exists)
I am unable to find a libxine2-plugins package, but not sure I am looking in the right place. I assume there is a "developer" or "bleeding edge" repo clausmuus added it to, but not sure how to pull from it.
Currently from "testing"
