Bonjour,
J’utilise Debian Squeeze avec KDE4 sur mes postes de travail. Ma principale machine est une 64bits. Jusque-là, je suis très content de tout ça. Il me reste quelques broutilles à voir. Une chose après l’autre.
Voici ma Webcam :
[kikinovak@alphamule:~] $ lsusb
Bus 002 Device 002: ID 046d:0928 Logitech, Inc. QuickCam Express
...
Lorsque j’essaie de tester ce que ça donne, je n’obtiens pas de vidéo, juste la série de messages que voici :
[code][kikinovak@alphamule:~] $ mplayer tv://

Exiting… (End of file)[/code]
Et là, je n’ai pas la moindre idée de ce que je peux faire. Quelqu’un a une suggestion ?
Remarque : la machine tournait sous Ubuntu 10.04 64bits avant, et la webcam fonctionnait.
