[Gelöst] Interne Webcam Probleme uvcvideo faile to query, qtcam-git, videoencorder veraltet


#1

Hallo,
meine Webcam hatte mal funktioniert, mit der Software wxcam. Wollte wxcam neu installieren. also wxcam deinstalliert und wollte neu installieren, wxcam erscheint aber nicht mehr im Paketmanager.

Cheese meldet: Fehler beim Abspielen des Webcam Videosignal.
Video und optical ist unter Benutzer als Gruppe aktiviert.

Dann mit qtcam-git versucht. Da kommen viele Fehlermeldungen “veraltet”.
Im Netz, im Wiki und hier nach Lösungen gesucht.

Cam geht wieder. Was genau die Lösung war, weiß ich nicht.
Ich habe jedenfalls in /etc/modules-load.d/modules.conf
Die Kamera zusätzlich eingetragen.

Die Datei sieht jetzt so aus:

# List of modules to load at boot
nouveau
nvidia
#Kamera
uvcvideo
