J'ai installé Logitech c920. Avec l'aide d'un utilisateur expérimenté d'AskUbuntu, j'ai installé GUVCview, le panneau de contrôle Video4 linux et le testeur d'utilitaires QT V4L2 ici. Je peux passer de la webcam intégrée de mon Toshiba à ma webcam externe en utilisant GUVCview.
Cependant, lorsque je démarre un chat vidéo sur Google Hangouts, il sélectionne automatiquement ma caméra pour ordinateur portable intégrée par défaut. Je voudrais modifier mes paramètres par défaut pour toujours utiliser une caméra externe, mais je ne trouve pas où se trouve cette option. J'utilise Windows 7 et Ubuntu 12.04 LTS sur Toshiba Satellite L755
mémoire: 3,8 Gib
processeur: CPU Intel® Core ™ i5-2410M à 2,30 GHz × 4
graphiques: Intel® Sandybridge Mobile
Type de système d'exploitation 64 bits
disque: 40,2 Go
EDIT: J'ai essayé Gstreamer-properties
dans le terminal et changé l'entrée par défaut sous la vidéo en caméra externe Logitech. Toujours pas de chance. Lorsque je "teste", je n’obtiens aucune image et je reçois toujours une caméra pour ordinateur portable lorsque j’ouvre GUVC.
2ème EDIT: Après avoir installé le sélecteur multimédia dans le terminal, je ne pouvais toujours pas le trouver dans Dash. Voici la lecture après l'exécution de la commande:

Si je cours Gstreamer-properties
dans le terminal, j'obtiens le sélecteur multimédia. Je change l'entrée par défaut en externe, la lumière bleue sur la came externe s'allume (lorsque j'appuie sur "test"), mais pas d'image. Voici une capture d'écran des paramètres
3ème EDIT: Après l'avoir exécuté en tant que root avec sudo gstreamer-properties
j'ai changé l'entrée par défaut en webcam HD (mêmes paramètres que la capture d'écran précédente) et stil lorsque j'ouvre GUVC, il s'ouvre en tant que caméra d'ordinateur portable. Voici ce qu'était la lecture après avoir exécuté SUDO

Lorsque j'ai essayé de fermer Terminal, il a indiqué que le processus était toujours en cours d'utilisation.
4ÈME ÉDITION, le lendemain:
J'ai suivi le lien ci-dessous vers Dumindu
sudo apt-get install gstreamer-dbus-media-service gstreamer-tools gstreamer0.10-alsa gstreamer0.10-buzztard gstreamer0.10-buzztard-doc gstreamer0.10-crystalhd gstreamer0.10-doc gstreamer0.10-ffmpeg gstreamer0.10-ffmpeg-dbg gstreamer0.10-fluendo-mp3 gstreamer0.10-gconf gstreamer0.10-gnomevfs gstreamer0.10-gnonlin gstreamer0.10-gnonlin-dbg gstreamer0.10-gnonlin-doc gstreamer0.10-hplugins gstreamer0.10-nice gstreamer0.10-packagekit gstreamer0.10-plugins-bad gstreamer0.10-plugins-bad-doc gstreamer0.10-plugins-bad-multiverse gstreamer0.10-plugins-base gstreamer0.10-plugins-base-apps gstreamer0.10-plugins-base-dbg gstreamer0.10-plugins-base-doc gstreamer0.10-plugins-cutter gstreamer0.10-plugins-good gstreamer0.10-plugins-good-doc gstreamer0.10-plugins-ugly gstreamer0.10-plugins-ugly-doc gstreamer0.10-pocketsphinx gstreamer0.10-pulseaudio gstreamer0.10-qapt gstreamer0.10-sdl gstreamer0.10-tools gstreamer0.10-vaapi gstreamer0.10-vaapi-doc gstreamer0.10-x
et a couru à travers le terminal. Après quelques minutes, le script a été fait et je n'ai pas remarqué d'échecs ou d'erreurs (je mettrai une copie ci-dessous). Cependant, lorsque j'ai couru, sudo gstreamer-properties
j'ai reçu les mêmes messages "Ignorer le plug-in indisponible" que ci-dessus ^. L'entrée par défaut sur le sélecteur de systèmes multimédias est définie sur c920 HD cam, mais je viens d'ouvrir GUVC et d'ouvrir la caméra pour ordinateur portable. Voici la lecture après sudo apt get install

mv /dev/video0 /dev/video1.bak
pour renommer le premier appareil photo (commeroot
ofc) - l'appareil disparaît, il n'y en a pas/dev/video0
ou/dev/video1.bak
plus. Je ne peux donc pas utiliser cette solution de contournement. D'autres idées?Je ne sais pas si c'est la meilleure façon, mais avec la même webcam et le même problème que j'ai trouvé, l'utilisation de la commande
sudo rm /dev/video0
supprime ma webcam. Il est parti jusqu'au redémarrage. Vous devrez peut-êtrecd /dev
et assurez-vous que votre webcam estvideo0
ma c920video3
.la source
Vous devez d'abord installer l'application Multimedia Systems Selector
Ensuite, ouvrez-le et dans sa
Video
section, vous pouvez changer la webcam par défaut.** Cette application peut être ouverte avec Terminal en exécutant:

sudo
Eh bien, ce genre de mort dans l'eau. Je ne sais pas si je devrais poster un autre fil ou quoi. J'essaie simplement de faire de ma webcam externe ma webcam par défaut. J'ai installé Gstreamer (photo) J'ai installé un sélecteur de systèmes multimédias. J'ai des paramètres par défaut dans le sélecteur de systèmes multimédias à définir sur la webcam c920, et pourtant, lorsque j'ouvre le chat vidéo ou le GUVC, il ouvre la caméra portable. J'ai obtenu de l'aide à ce sujet et j'ai suivi. Mais je n'arrive toujours pas à le faire fonctionner. Quelqu'un a-t-il des idées ou dois-je poster ailleurs? Merci

Je pense que j'ai une solution. Je ne sais pas si vous pouvez faire fonctionner à nouveau votre propre appareil photo, mais au moins j'ai pu créer une clé USB par défaut.
Je l'ai fait comme ça:
sudo rm /dev/video0
Après cela, je n'ai plus pu démarrer Camorama Webcam Viewer.
sudo chmod -R 777 /dev
Cela vous donne la permission de changer les noms de fichiers
mv /dev/video1 /dev/video0
Cela renomme votre caméra USB en dev0
Après cela, j'ai pu voir ma caméra USB automatiquement lorsque j'ai ouvert Camorama Webcam Viewer. J'espère que ça aide.
