Quote from kfb77

Aus dem Backtrace kann ich nichts erkennen, installiere doch mal die Debug Version von markad. Falls das die Ursache sein sollte, sieht man vielleicht mehr. Was ich aber nicht glaube, weil bei mir geht das ohne Crash (allerdings mit VDR 2.7.3).

die Ausgabe bleibt identisch, wenn ich die markad debug Version installiere.

Aber der Segmentaion fault wird vom vdr-tvscraper-plugin (vdr-tvscraper-1.2.10-1.fc41.x86_64) verursacht, habe es deinstalliert.
Die Frage ist nun, was passt da nicht ?

Aufgrufen wird das Plugin mit diesem Parameter

--plugin=tvscraper --dir=/var/cache/vdr/plugins/tvscraper/

wenn ich aus der Konsole heraus starte mit

martin@fc41:~$ /usr/sbin/vdr -v /video -D1 -u vdr --vfat --userdump -s vdr-shutdown.sh --plugin='dvbhddevice' --plugin='softhddevice -g 1680x1050+100+100 -a pipewire -d :1 -v vdpau' --plugin='tvscraper'

mit dem tvscraper startet der vdr erst gar nicht.

Quote from MarkusE

Warum machst Du nicht den von mir vorgeschlagenen Test (nur tvscraper, sonst kein Plugin)?

Du kannst dazu in /etc/vdr/conf.d die Links zu allen Plugin-Konfigurationsdateien (außer tvscraper) löschen.

> mit dem tvscraper startet der vdr erst gar nicht.

Dann gibt es bestimmt Fehlermeldungen. Welche?

ich bin hier unter Fedora unterwegs, da gibt es kein conf.d

und eine Fehlermeldung gibt es auch nicht, das Kommando beendet sich einfach.

Bei Fedora wird über die /usr/sbin/runvdr im Verzeichnis
/usr/lib64/vdr nachgeschaut, welche Plugins existieren und die werden dann auch geladen, so interpretiere ich es zumindestens.

ich habe mal die Ausgabe von "journalctl --unit vdr -b" nach dem Ausführen von "vdr --version" angehängt.

ich habe mal die Änderungen von Thread segmentation-fault-bei-aufruf-von-vdr-help-mit-installierten-plugin-tvscraper
übernommen, weis nur nicht, ob die passen.
Damit jedenfalls tritt bei mir der Segmentation fault ebenfalls nicht mehr auf.

Ja, passt.

Danke für deine Rückmeldung.

Übernimmst du diese Änderung im git ?
