Programma per registrare con webcam

Fedora Linux Programmi
#1

Ciao
vorrei perfavore chiedervi cosa dovrei installare per registrare video con webcam.

Cheese scatta foto ma ha difficoltà (non va) a registrare un filmato.

Vi ringrazio per informazioni.

Grazie MarioS
questo programma va meglio di Cheese ma nel suono si sente
