Bonsoir,
j'ai une webcam intégré a mon portable acer 9920. Lorsque je lance Studio Webcam Cheese, la cam s'allume, mais aucune image apparait dans le cadre. J'ai regardé sur la doc Fedora pour l'install des cam mais je ne comprends pas tout sauf que j'ai cette ligne: 
Bus 002 Device 003: ID 064e:a101 Suyin Corp. Laptop integrated WebCam
J'ai effectué une recherche sur le web mais je tombe sur des post qui parlent de clef USB .. ou autre, ou alors pas vu.
Merci pour votre aide
le nouveau kernel ne comprend plus de "blobs" les firmware sont disponible séparément peut etre te manque t'il ça(celui pour ta webcam).
lance ton logiciel en console et regarde si il sort des erreurs.
ben j'ai pas d'erreur, c'est ca le soucis..
Il me dit pour tant dans la config :
ACER CRISTALEYES WEBCAM (/dev/video0)

Un truc bizarre est que des que je ferme la fenêtre le carré fond noir ou il doit y avoir la photo (image de la cam) apparait 1 seconde le temps que ça ferme..
je vais tenter avec ma webcam meme si ce n'est pas la meme
ta webcam utilise uvc...

beaucoup de changement avec 2.6.26 et 27 pour la gestion des firmwares
merci
je pense aussi que peut etre mes codecs video (et audio) sont pas du tout a jour

Heu, je crois que l'on s'eloigne du sujet. C'est un support pour une webcam en particulier, donc une autre webcam
Chez moi la webcam est reconnue automatiquement (portable Asus) et cheese fonctionne très bien.

@yatoula
Sinon Est ce que tu as le retour de la commande "dmesg"
c'est pas les codecs c est le fait qu'il y a eu une décision de n'inclure plus de trucs binaire dans le kernel maintenant

certaines webcam ont besoin de "blob" externe non?
tu peux coller ça ici avec la balise code, disponible dans le menu juste après la petite bulle pour les citations

c'est un liveusb?

pour avoir le dmesg au complet
dmesg > dmesg.txt
il se trouvera(le fichier texte) à l'endroit où "ton bash est".

c'est une clef usb kingston qui fait toutes ses erreurs? m'enfin aucun rapport avec ton soucis.
je suis allé dans préférences et sélectionner 176x144
pour avoir l'image, une autre résolution et c'est l'ecran noir.
Un pote a pareil sur son HP dv6000, ça ne marche qu'en résolution minimale.
idem pour un acer 5710z et aucun message d'erreur ni dans dmesg ni dans cheese
Effectivement, en mettant la plus petite résolution ça fonctionne, c'est dommage quand même... Il y a pas une solution ?
sans doute que ça sera regler dans une mise à jour ou le prochain kernel si le probleme a été reporter.
