Tengo Logitech c920 configurado. Con la ayuda de un usuario experimentado de AskUbuntu, instalé GUVCview, el panel de control de Video4 linux y el probador de utilidades QT V4L2 aquí. Puedo cambiar de la cámara web incorporada de mi Toshiba a mi cámara externa usando GUVCview.
Sin embargo, cuando comienzo un videochat en Hangouts de Google, selecciona automáticamente la cámara de mi computadora portátil incorporada de manera predeterminada. Me gustaría cambiar mi configuración predeterminada para usar siempre una cámara externa, pero no puedo encontrar dónde está esta opción. Estoy ejecutando Windows 7 y Ubuntu 12.04 LTS en Toshiba Satellite L755
memoria: 3.8 Gib
procesador: CPU Intel® Core ™ i5-2410M @ 2.30GHz × 4
gráficos: Intel® Sandybridge Mobile
Tipo OS de 64 bits
disco: 40,2 GB
EDITAR: Intenté Gstreamer-properties
en la terminal y cambié la entrada predeterminada en video a la cámara externa Logitech. Aún sin suerte. Cuando "pruebo" no obtengo ninguna imagen, y sigo teniendo la cámara del portátil cuando abro GUVC.
2nd EDIT: después de instalar el selector de medios múltiples en la terminal, todavía no pude encontrarlo en Dash. Aquí está la lectura después de ejecutar el comando:

Si corro Gstreamer-properties
en la terminal obtengo el selector multimedia. Cambio la entrada predeterminada a externa, la luz azul en la cámara externa se ilumina (cuando presiono "probar"), pero no aparece ninguna imagen. Aquí hay una captura de pantalla de ajustes
3rd EDIT: después de ejecutarlo como root con la sudo gstreamer-properties
entrada predeterminada que cambié a cámara web HD (la misma configuración que la captura de pantalla anterior) y aún cuando abro GUVC, se abre como una cámara portátil. Aquí está la lectura después de ejecutar SUDO

4ta EDICIÓN, al día siguiente:
Seguí el enlace de abajo a Dumindu's
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
y corrió eso a través de la terminal. Después de unos minutos, el guión se realizó y no noté ningún error o falla (pondré una copia a continuación). Sin embargo, cuando ejecuté sudo gstreamer-properties
, recibí los mismos mensajes de "Saltar el complemento no disponible" que el anterior ^. La entrada predeterminada en el selector de sistemas multimedia está configurada en c920 HD cam, pero acabo de abrir GUVC y abre la cámara del portátil. Aquí está la lectura después de sudo apt get install

Primero debe instalar la aplicación Selector de sistemas multimedia
Luego ábralo y en su
Video
sección, puede cambiar la cámara web predeterminada.** Esta aplicación se puede abrir con Terminal ejecutando:

Bueno, este tipo de cayó muerto en el agua. No sé si debería publicar otro hilo o qué. Simplemente estoy tratando de hacer que mi cámara web externa sea mi cámara web predeterminada. Tengo instalado Gstreamer (en la imagen) Tengo instalado el selector de sistemas multimedia. Tengo la configuración predeterminada en el selector de sistemas multimedia para configurar en Webcam c920 y, sin embargo, cuando abro el chat de video o GUVC, abre la cámara del portátil. Obtuve algo de ayuda en esto, y lo seguí. Pero todavía parece que no puedo hacer que funcione. ¿Alguien tiene alguna idea, o debería publicar en otro lugar? Gracias

Creo que tengo una solución. No sé si puede hacer que la cámara de su computadora portátil vuelva a funcionar, pero al menos pude hacer un USB por defecto.
Lo hice así:
sudo rm /dev/video0
Después de esto, no pude iniciar Camorama Webcam Viewer en absoluto.
sudo chmod -R 777 /dev
Esto le da permiso para cambiar los nombres de los archivos.
mv /dev/video1 /dev/video0
Esto cambia el nombre de tu cámara usb a dev0
Después de eso, pude ver mi cámara USB automáticamente cuando abrí Camorama Webcam Viewer. Espero que esto ayude.
